Plant Experimental Design
i) PURPOSE: To determine whether added nutrients speed up seed
germination.
HYPOTHESES: "The plants with the nutrients will grow better."
ii) EQUIPMENT:
1. 10 pinto beans
2. 1 500 ml jar
3. distilled water
4. 1 refrigerator
5. liquid plant fertilizer (5-10-5)
6. 1 4 litre plastic milk jug
7. 1 marking pen
8. masking tape
9. paper towels
10. paper towels
11. 2 straight sided drinking glasses
12. 2 sheets of black construction paper
13. 1 stapler
iii) METHOD:
1. Put the beans in the jar and cover them with distilled water.
2. Place the jar of beans into the refrigerator, and let them soak
overnight.
3. Prepare 4 litres of the liquid plant fertilizer by following the
instructions on the package. Use the distilled water to mix the
fertilizer in the milk jug.
4. With the marking pen, write ''Nutrients'' on a piece of masking
tape and tape this label to the jug of liquid fertilizer.
5. Prepare two separate containers of beans as follows:
a. Fold one paper towel and line the inside of a glass with it.
b. Put together several paper towels and stuff them into the glasses
hold the paper lining against the glass. c. Place five beans between
the glass and the paper towel lining, evenly spacing the beans around
the perimeter of the glass.
6. Use the marking pen and tape the label one glass ''Water'' and to
the second glass ''Nutrients''.
7. Moisten the paper towel in each glass with either distilled water
or plant fertilizer as indicated. Keep the paper towels in the glasses
moist, but not dripping wet, during the entire experiment.
8. Cover the outside of each glass with one sheet of black
construction paper. Fold and staple the top and sides of the paper.
9. Each day, until the bean grows , remove the paper covering from
Materials: 3 400 ml glass beakers, 3 whole tablets of Alka Seltzer, thermometer, stopwatch/timer, thermal glove, hot plate, ice bath
2. Drop a gummy bear into each of your prepared beaker or cup and place the beaker or cup
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
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.
After the addition of the media, we insert an aeration tube inside and cover the lid with a cotton plug and start giving them aeration. This preparation has to be put on for 3 days under proper sunlight and 25-30 degree Celsius to observe if the culture is healthy/ potent or not depending on the color each culture portrays (The nanochloropsis culture should have a grass-green color to be seen as potent and the isochrysis culture should have a dark brown color to be seen as potent), if the colors seem dull and light, then that might mean that the culture is impotent.

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.
* Count the number of bubbles seen in 1 minute which is a way of
7.) After you have heated them to the right temperatures, pour the excess water into a dry evaporating dish. ( Be sure not to get any of the substance in your solution. )
The plants that we know today as terrestrial organisms were not always on land. The land plants of today can be linked back to aquatic organisms that existed millions of years ago. In fact, early fossil evidence shows that the earliest land plants could have arisen some 450 million years ago (Weng & Chappie 2010). Plants that used to reside strictly in water were able to adapt in ways that allowed them to move onto land. It is speculated the need for plants to move onto land was created by water drying up, causing plants to have less room and pushing them to move onto land. Although the exact cause of plant’s need to move to a terrestrial environment is unclear, it is known that plants had to undergo several adaptations to be able to live on land. These adaptations include: lignin, cellulose, suberin, and changes to plant’s surface, including the formation of a waxy cuticle.
1. Obtain a clean, dry crucible and lid, then heat them for approximately 5 minutes over a Bunsen burner
2. In the large beaker, put water and boil it completely. After that, remove the beaker from heat. 3. Sample tubes (A-D) should be labeled and capped tightly.
...lute the perceived concentration of ABA. As ,mentioned before, I purposely didn’t go into too much detail here because most people know about soaking seeds in water and scarification. I just included it here to give a scientifically explanation as to exactly HOW these methods work. It still all boils down to ABA.
Asexual propagation is the process through which reproduction without passage through the seed cycle occurs. The advantages of asexual propagation are that it preserves genetic makeup, propagates seedless plants, disease control, rapid production, the plants are identical, cheaper, faster and easier reducing or avoiding juvenility. The disadvantages of asexual propagation are that it increases disease and insect susceptibility, plants are bulky, and the mother plants could become contaminated. The goal of this experiment was to determine the development of adventitious roots and shoots, and observe these plants over a period of five weeks. Due to auxin being produced in the tip, tip cuttings should root faster than any other cuttings. Auxin is a plant hormone that is responsible for cell elongation and enlargement, root formation, and growth. There are two forms of auxins; phototropism, which is produced in the tip and moves downward on the side away from the light and gravitropism, which is where plant roots grow downward and plant shoots grow upward.(Plant Auxin 201...
Prepare silica gel column. Add 6 g of silica gel in 20 mL of hexane to make a slurry. Block column with small piece of glass wool, add 5 mL of hexane and then add the silica slurry up to the 10 cm mark.
