Plant Location Lab
Background: This investigation involves with dependents of plants around the world growing constantly. Recently, plants have been growing at a slow ate without any sunlight. According to scientists, plants are now growing without light and effects the development stages. The longer the measurement of the seeds to bloom, the longer the estimating growth rates between 2 weeks to 2 months to evolve.
Scientists pointing out saying that plants will grow rapidly without sunlight. The plants are supposed to be grow with photosynthesis and respiration. Without the photosynthesis, then the location of the biome would depended the outcome of plant growth. For the research question, how does changing the concentration of plant growth

Some plants have different shapes and sizes of the plants’ growth while others do not.
Independent variable: Light
- Sunlight and light classrooms will only affect the plants at a certain time limt because the plants are place inside the building and near the windows.
Controlled variable: Methods, plant samples, temperature
- Methods on trying to figure out where to put each plant sample near from the back, the front or in the center of the inside. Each plant sample will be given a letter and the name of the plant named on the cup. The temperature will be running inside the building to collect data of the results and the amount of water given will determined the plants from growing.
- There will be two groups of 3 different type of plants that will be measure on how long the stomata is growing, the amount of water each day and the location.
Uncontrolled variable: The locations of the inside of the classroom and light.
- Light will only be inside and outside of the classroom.
Materials:
● Three medium transparent cups with the sizes of 1 to 3 inches
● Three large non-transparent cups with the sizes of 1 to 3

The hypothesis states the plants will grow faster under the sunlight and their growth rate would increase. The data shows that each plants growth and how the temperature effects them from growing. Photosynthesis, transpiration and respiration play a basic part of the plant growth. Yet, there are issues behind plant growth is lack of water, weak soil, and over watering plant. Over watering affects the plants from growing when the soil absorbs the water too fast, and the nutrients won’t have the time to absorb it rapidly. Lack of light could also affect the plant’s growth becomes slow and plants fails to bloom. The solution would be to reduce room temperature by amount 3 Celsius and pour water less frequently. These growing problems are the reason why both group included samples B and C (1st group) and samples A and B (2nd group) were not
Two members of the group were instructed to visit the laboratory each day of the experiment to water and measure the plants (Handout 1). The measurements that were preformed were to be precise and accurate by the group by organizing a standardized way to measure the plants. The plants were measured from the level of the soil, which was flat throughout all the cups, to the tip of the apical meristems. The leaves were not considered. The watering of the plants took place nearly everyday, except for the times the lab was closed. Respective of cup label, the appropriate drop of solution was added to the plant, at the very tip of the apical meristems.
The reason the plant will grow taller and at a faster rate is because of the properties that plant food has. Plant food provides crucial nutrients to the plant that will make it stronger. It also gives the plant energy to
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
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.
Investigating the Effect of Light Intensity on the Size of a Plantain Leaf Title: To investigate the effect of light intensity on the size of a plantain leaf. Hypothesis: I predict that the size of the plantain leaves would increase as the light intensity decreases. Therefore, plantain leaves found in the shade will have larger surface areas than leaves found in an open area. Theory: Sunlight is an essential factor need to complete the process of photosynthesis.
... photosynthesize. Without the vital factors of; carbon dioxide, water, sunlight and chlorophyll, plants would not be able to photosynthesize and therefore would not be able to produce their own food and thus would die. Without plants there would be no life on earth as basically all animals are directly or indirectly reliant on plants for their food as they are not able to produce their own food like plants. It is therefore crucial that plants get all these factors that they need in order to photosynthesize because, they are so important for the well being of the whole world, not only for food but also giving us the oxygen we need to breathe and stay alive, as they let off oxygen as a bi-product. To further improve this experiment one could test how the amount of carbon dioxide influences the rate of photosynthesis and therefore the speed at which a plant can grow.
To develop techniques of measuring the size of plant fibers under microscope using stage micrometer and eyepiece graticule.
the effect light has on the growth of pea plants. It will take place in an environment with controlled light, with equal amounts of plants being grown in the light and in the dark. All elements of the experiment other than light will be kept the same, such as amount of seeds in each pot, amount of soil in each pot and amount of water given to each plant each day. This will ensure a fair experiment. Prediction: I predict that in general, the plants grown in the light will grow better than those grown in the dark.
C4 plants are will grow more in warm weather. Warm weather causes a plant to close their stomata to save water in warm temperatures. When this process occurs
It controls the direction of growth in stem tips in response to different stimuli including gravity and light. The way the plant grows depends on the distribution of auxin in the plant tissue. Auxin is made at the tip of the stem, and then flows downwards. Auxin is vital to the survival of plants because it allows the plant to photosynthesize as much as possible. Light destroys auxin, so when it strikes the stem it kills the auxin on the side nearest the light source, causing an imbalance of auxin. Because more auxin is present on the side facing away from the light source, that side grows faster causing it to tilt and bend towards the light. That process is phototropism. Gravity pulls auxin to the lower side of the stem, therefore the lower side of the stem grows faster. That means that the plant will grow upwards and against gravity. For example, if a plant were placed horizontally, the force of gravity causes the auxin to move to the underside of the stem. Because of the increased amount of auxin, the cells on the bottom side of the stem grow more than the cells on the top side of the stem, causing the stem to bend upwards. A study, done by Ken Haga and Tatsuya Sakai proved that phototropism and gravitropism occur because of
The investigation was completed over a period of a week for a wide range in the results to base experimental conclusions. From the primary data obtained, the pattern of the results supported the hypothesis and followed the trends of the theory discussed earlier and also the reflection spectra (Figure 2). The vertical growth of height table and graph (Table 1 & Figure 3) demonstrates the effects isolated colours of light have on the vertical growth of plants via mung beans. In the experiment of this investigation, vertical growth of the specimens of mung beans under the different colours of light was measured in response to time in days. From the results collected, all the values were expected and assisted to validate the findings of secondary experiments conducted by previous researchers.
Plant growth is the enlargement or the increase in height of a plant. From the seeds that was planted under the soil and in to a plant that emerge from the soil. The growth of plants is a natural process that occurs every time a plant is being planted. Plants have cells that help them to grow or increase in size, mass or the other parts of the plants. Not all plants grow as tall as a tree it is according to their origin or type of plant that the seeds came from, for example, mongo seeds do not grow as tall as trees like bonsai, the shrubs and flowers. Some plants grow as tall as trees as or more than the size of it, like the bamboo they grew as three feet tall.
Competition for scarce resources can decrease or retard growth and development. Up to a point, plants respond to competition by modifying form and size.
Microclimates nurture wide varieties of plants and animals. Preivously it was established that microclimate is important to plant for different activities like germination, growth and reproduction.Necessary to plant species for germination, growth and ecological processes, such as photosynthesis, evapotranspiration, nutrient cycling (Rosenberg et al., 1983). Biotic and abiotic process rates are effected by soil temperature and moisture, such as nutrient availability, soil carbon sequestratio, and microbial activity (Fisher and Binkley, 2000). Active microbes and invertebrates along with high temperature and moisture, can also lead to a faster litter decomposition and thus enhance vegetation (Godefroid et al., 2006).
Plants use sunlight in the same way food is used by humans. People and animals get their food by eating it. Plants make their own food by using air, water, nutrients and energy from the sun (Rissman, 2009, p.5). While plants take care of their survival, it is worth noting that if the habitat changes in anyway this may present a challenge to the life of a plant.
