Introduction
Observations: Many variations and species of plants can be found all around the world and in different habitats. These variations and characteristics are due to their adaptations to the natural habitat surrounding them. In three of many climatic zones, the arid, tropical and temperate zone, plants that vary greatly from each other are found in these locations. In this experiment, we’ll be observing the connection between the adaptations of the plants to their environment at the Fullerton Arboretum. The arboretum is a space containing numerous plants from different environments. The plants are carefully looked after and organized into their specific habitat. Therefore, we’ll be able to take a look at the plants within multiple

Depending on the biomes, rainfall and soil can vary. However, the rainfall is typically ranges from 30 cm to 200 cm. In mountainous regions and forest biomes, there would be plenty of rainfall. While in the grasslands, there’s little rainfall. In the temperate zone, there are two main types of trees, coniferous and deciduous. The deciduous trees, in the South, drop their leaves in the winter. Generally, the trees are usually small in height unless in the forest areas. The forests tend to have wide leaves and tall, large trees. The soil in deciduous forests is found to be very fertile. The different amount of rainfall in the forest areas and the grasslands cause the difference between the trees and plant height. The rainfall in forest regions can lead them to be very common with the rainforests. Furthermore, the changes and variation of weather could be the reason as to why the forests shed or don’t shed their leaves. The leaves show a correlation between the fair amount of sunlight during the summer causing the leaves …show more content…
Some sources of error in my experiment can be found mainly in my research of the tropical trees. In the tropical zone and temperate zone, most trees were too tall to reach and examine their leaves. Furthermore, it was hard to get the entire tree within our pictures. Therefore, this caused little information about the large trees in the tropical zone, giving our information less variation. This error was also implemented throughout all the zones. Another source of error was with the light shining upon the leaves. During our experimentation, there were moments in time where the sun was hidden and the sun was shining brightly. Therefore, possibly affecting the color of our leaf color. The sunlight may cause our leaf to look lighter than they possibly are. This could cause false information to compare the leaf colors for each biome. To improve my procedure, there are plenty of different ways to do so now that I have an increased experience with working with a large selection of trees. A major flaw with my research is by having to record the different types of trees in the zone, mainly height. Therefore, having to examine trees that vary greatly from each other. By having trees that represented the whole zone, instead of part of a zone, it would give more accurate information. To achieve even more accurate information, looking at the largest leaf for each tree would give a better
The “Fast Plant” experiment is an observation of a plants growth over the span of twenty-eight days. The objective is to observe how plants grow and use their resources throughout the span of their life. In our lab we observed the Brassica rapa, a herbaceous plant in the mustard family which has a short cycle which makes it a perfect plant to observe in this experiment. Like other plants the Brassica rapa must use the resources in the environment to create energy to complete itʻs life cycle and reproduce. By observing the plant it is easy to see in what organ or function the plant is using itʻs energy and resources and if overtime the resources switch to other part of the plants. By conducting this experiment we are able to observe where and how plants allocate their resources throughout their life by harvesting plants at different points in their life.
The fast plant seeds were planted in a terrarium and a variable was added to see what happened when the variable was added to compare the regular growth of plants without and with the variable. There was a land part of the terrarium where the fast plant seeds were planted and a bottom part where there was water which was to water the plants through a rope. The plants without the variable grew pretty quickly and almost always grew up. The one time their average dropped was because one of the plants’ necks got snapped which dropped the plant from 13.5cm to 10 cm causing the average to drop from 11.3cm to 10.5cm. The fast plants grew pretty steadily and the final average height was 19.5 cm. The variable that got put into the
My science fair project is about comparing sun leaf and shade leaf. The purpose of my project is to find out the answer of these questions: Do leaf size and shape according to their position on the tree? What are the differences between sun and shade leaves? How does photosynthesis work on plants? In this experiment I compared leaves of the same plant that grows in high light and low light environments, and observe that the low light plant has adapted to increase its efficiency of light capture for photosynthesis.
The trees of Heiberg Forest vary greatly by area. One area could be heavily shaded by huge mature trees, with rich, cool and moist air. Another could be a much sunnier area, with younger trees and sapplings. Just a few steps can take you to a completely different atmosphere. There is a reason why certain areas are the way they are. Factors contributing to the trees of an area can range from land use history, soil quality, or human intervention. One leading component, perhaps the most important, is seed regeneration. The way a tree species disperses seeds to reproduce will affect its success in certain areas. Some trees disperse their seeds in a close range, some are carried by the wind, and others are carried by animals.
Have you ever wondered if a plant knew it was about to be dinner? Heidi Appel and Rex Cocroft were perplexed with whether or not plants could communicate with, not only themselves but also other plants, about chemical defenses. According to new research, plants may have their own “cell”-phones. When a hungry caterpillar starts chowing down on a bitter leaf that might just be the case.
The Exploratorium was a great experience, there was a lot of things to do and experiment with. There was things like a smoke ring maker and a voice modulator that could make your voice higher or lower. There was this one invention that blew out air and a ball would float in mid air and it would hover in the air as long as the wind was blowing. Also there was this tube that was filled up with water. There was also this knob that controlled sound that would be eliminated in the tube, and the more high pitched the sound was the the more the water would move. Also this one exhibit had a shredded magnets in a bigger tube and then there was two magnets. One on each side and the tube was filled up with water and when you took some of the shredded
Plants in a Temperate Forest can survive because rain falls all year long. They can also survive because when the leaves drop from the deciduous trees, it enriches the soil with nutrients, allowing the trees to continue to grow. Because of this, the enriched soil the plants and trees have deep roots. The plants have broad-leaves to catch and store sunlight. They store sunlight not only because they need it to do cellular respiration at night but also because in a Temperate Forest the winters are cold. These types of trees are mostly found in North America, Asia, and Europe. They can also be found in Australia and South America
In the lab exercise regarding plant structure and function, we examined slides containing the different kinds of roots (monocot, dicot). We labeled the parts and pointed out the different roles of each in the plant structure. Also, we examined monocot stems and dicot stems in order to familiarize ourselves with its external and internal structures. We sketched and labeled the parts of the stem and looked closely at the positions of each part. In the last part of the lab, we classified leaves into different kinds according to their leaf venation, bases of leaves, and apices of leaves. As an additional exercise, we sketched 20 animals and classified them according to phylum and class. We were also able to discover the scientific and common names of the animals. Overall, the exercises we did enabled us to familiarize ourselves with plant structure thus, gaining a better understanding for plant life and its importance.
There have been solid connections between tree distributions, and its abundance to the soil nutrient that it inhabits4. Other factors such as Accessible light, water supply and temperature also influences the success and growth of tree species1. One difference why Oldfield showed more percentage of species covering the ground is because Oldfield is abundant in grass fine leaved and flat leaved while that is not common in
My honors biology project is creating a closed vivarium that will eventually be able to support itself. I am conducting this experiment for my honors biology project. I will include a small African Violet , a Lemon Button Fern , and an earthworm to decompose and generate the nitrogen cycle. This ecosystem will have to be able to maintain strong carbon, nitrogen, and water cycles to survive. A few organisms in a small container can work together to maintain a stable environment.
2. Characteristics of this family typically resemble the harsh conditions the Australian environment offers the plants. Tall trees of Myrtaceae are coated with a smooth bark, which shed annually for their protection against fire sensitive areas. The leaf surface has tiny dots called oil glands and their flowers form in groups. Research has also shown that they also have multiple stems arising from the surface. These stems appear to be new adaptations measures against their high fire prone habitats (Peter G. Wilson, 2011). Some species of Myrtaceae family found in rainforest habitats are usually are broad and mesophylls, with the presence of acuminated tips as their leaf morphology; whereas species of arid or coastal regions often have smaller, narrower leaves which sometime have a scale like sensation, whilst keeping the leaves simple and non-vascularized tooth like projections adaptations (Peter G. Wilson, 2011).
Trees have fascinated humans for thousands of years and have played a major role in mythologies all over the world, largely because of their utility, longevity, and often impressive stature. Additionally, trees play a major role in the ecology of the Earth by reducing erosion and moderating the climate by removing CO2 from the atmosphere and storing large amounts of carbon in their tissues (Kozlowski 1971). Trees have copious uses for all different types of plants and animals; food, shelter, fuel, and timber being a few of the most common uses. There is no universally recognized precise definition for trees. They are not a distinct taxonomic group, but rather a collection of plant species that have independently evolved similar traits. The most characteristic of these traits is a wooden trunk and branches which are used as a way to tower above other plants. One of the broader definitions of trees classifies them as: “any plants with the general form of an elongated stem or trunk, which supports the photosynthetic leaves or branches some distance above the ground,”(Tokuhisa). More generally, trees are often defined by height, with smaller plants being classified as shrubs, though the minimum height varies widely. Another specification used to differentiate between trees is the presence of a wooden trunk, although this excludes herbaceous trees such as bananas and papayas (What is a tree?). Despite being herbaceous and never producing wood, palms and bamboos may produce a wood-like substance by lignifying cells produced through primary growth, and are able to stay tall and rigid due to cellular water pressure called “turgor” (What is a tree?). Trees exist in two different groups of vascular plants, the gymnosperms and the angiosperm...
The rainforest is full of forests and trees, dripping with water, hence the name.There are swampy parts and there are very few plants that can survive under the canopy layer. The rainforest can be found in between the tropic of Capricorn and the tropic of Cancer. It appears only on 6% of the Earth’s surface and around the equator. The largest rainforest today is the Amazon Rainforest is 2.1 million miles and would rank the 9th if it was a country. There is no fertile soil because it is washed out with rain. The first layer is the ground layer and is filled with bugs and a few plants. Next comes the lower layer and then the understory. Following is the canopy and that is which most lives thrives. It can release about 200 gallons of water a year. Then the emergent layer is where the sunlight is the most.
It often rains over 100 inches however there is usually a season of less rain. The average humidity is between 77% and 88%. The rainforest is made up of four levels. The top level is the emergent. (3) This is the tops of the highest trees where the branches are spread far apart. (1) The emergent layer is high up and in direct contact with the sunlight, making it very hot and windy. (3) The next level is the canopy. (1) The canopy is very dense and receives lots of water from the frequent rain showers. It has the most animal activity. (3) The level below the canopy is the understory. (3) Because it receives very little sunlight, the understory is cool and shady. (3) The forest floor is the level below the canopy. (3) It also receives very little sunlight and has very few plants. (3) It is home to some of the largest as well as some of the smallest creatures of the tropical
