Place 25 dormant peas into a plastic cup. Keep pouring non-chlorinated into the plastic cup until it’s about 3 times the height of an dormant peas. Allow the peas to germinate overnight.
2. Drain the non chlorinated water from the plastic cup. Place the germinated peas on a saturated paper towel of non chlorinated water and put inside a ziplock bag. Place the bag in a dark place overnight.
3. Add 25 mL of nonchlorinated water to the 100-mL graduated cylinder.
4. Slowly drop 25 germinating peas into the graduated cylinder.
5. Observe the final volume (VF) after adding the peas to the graduated cylinder. Record this value in Data Table 1 for germinating peas.
6. Determine the volume of water that has been displaced, by subtracting the initial volume of water from the final volume (VF) after adding 25 germinating peas. The difference in volume is

Remove the germinating peas and place them on a paper towel saturated with non chlorinated water.
8. Refill the graduated cylinder with 25 mL of non chlorinated water.
9. Slowly drop 25 dry, dormant peas into the graduated cylinder.
10. Gradually add beads to the graduated cylinder containing dormant peas so that the final volume equals the final volume measured previously for the germinating peas. 11. Remove the dormant peas and beads, and place them on a dry paper towel (keep them separate from the sample of germinating peas).
12. Record the volume of the dormant peas and beads in Data Table 1. The volume should be the same as that entered for the germinating peas.
13. Refill the graduated cylinder with 25 mL of water.
14. Gradually add beads so that the final volume equals the final volumes of the germinating peas and the dormant peas plus beads. All three groups should have equivalent volumes at the start of the experiment.
15. Remove these beads and place them on a dry paper towel (keep them separate from the sample of dormant peas plus
Cellular respiration is the process by which energy is harvested involving the oxidation of organic compounds to extract energy from chemical bonds (Raven & Johnson, 2014). There are two types of cellular respiration which include anaerobic respiration, which can be done without oxygen, and aerobic respiration, which requires oxygen. The purpose of this experiment is to determine whether Phaseolus lunatus, also known as dormant seeds or lima beans, respire. You will compare the results of the respiration rate of the dormant seeds, and the Pisum sativum, or garden peas. In this experiment, you will use two constants which will be the temperature of the water and the time each set of peas are soaked and recorded. Using these constants will help
2. Drop a gummy bear into each of your prepared beaker or cup and place the beaker or cup
In separate test tubes 6. Cut each celery piece into 5 cm cubes and place into test tubes 7. Leave for 30 mins at room temperature 8. And collect the strips out of the test tubes, dry them and record the mass of each strip Prediction I predict that as the concentration of sucrose increases, The cell will firstly become turgid, as since the concentration is low the water potential outside the cell will be higher than inside to water will diffuse in. Then as the concentration gets higher the water potential outside will become lower than inside the cell so water will diffuse out and the cell will become plasmolysed.
In my experiment, I will use an overall volume of 50 cm³ of 2moles of
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.
At point A the graph shows that no change in mass, of the potato, would have have occurred had we used a 0.2 (m) sucrose solution. This suggests that the concentration of water inside the potato would have been equal to the solution outside the potato. At point B (plain water), there is no indication that the cell is increasing in mass. This is because the cell is fully turgid and no more water can enter.
Garden pea plants have some traits that are easy to see, which made it possible for Mendel to produce observable results. Mendel studied seven traits. Each of these traits is unusual in that it has only two distinct forms. For example, the pea pods are either yellow or green. There is no intermediate or blended color. The height of the plant is tall or short, never medium. Distinct traits like this are rare in nature, as you will see later in this unit. The distinct traits in pea plants allowed Mendel to see his results without guesswork. Another important feature of pea plants is that most plants reproduce in about 90 days. The short reproductive cycle gave Me...
3.) Divide your 30g of white substance into the 4 test tubes evenly. You should put 7.5g into each test tube along with the water.
6. Unscrew cap on Penicilium italicum culture tube with one hand and flame the mouth of the tube.
Every student in a lab section planted eight seeds, two in each cell in a quad, to make sure that we had at least one plant for each week for 4 weeks. After planting the seeds we put the plants on a water mat tray to make
We then cut our potato tubes with the cork borer and cut them with the scalpel so they were the same length and weighed them. We then put one potato tube in each test tube and then added the same amount sugar solution in to each tube. The concentration of sugar solutions varied in each test tube.
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.
4. Put each group of potato discs in one of the 6 test tubes and watch
