Question 1

Your friend Bill says that all food on Earth ultimately comes from photosynthesis. Your friend Tom disagrees, saying that, "Cows and pigs don't photosynthesize, and they are food." Who do you think is correct, and why?

Accepted Answer

The answer of Your friend Bill says that all food...

Question 2

You perform an experiment using an aquatic plant called elodea to determine which color of light is most effective at driving photosynthesis. You take three plants, immersed under water, and place plant A under blue light, plant B under red light, and plant C under green light. You notice bubbles coming off the leaves. More bubbles are coming from plants A and B, and few are coming from plant C. What is producing the bubbles? How do these results determine which color of light is most effective at driving photosynthesis?

Accepted Answer

The answer of You perform an experiment using an aquatic...

Question 3

Question 5

Photosynthesis forms ATP using oxidation-reduction reactions similar to those seen in the electron transport chain of respiration.

Accepted Answer

Photosynthesis does indeed use oxidation-reduction reactions to create ATP, just like respiration. These reactions involve the transfer of electrons, which creates a gradient of energy that drives the production of ATP in both processes.

Question 6

If something is oxidized, it loses electrons.

Accepted Answer

Oxidation is the process where a substance loses electrons, resulting in an increase in its oxidation state.

Question 7

Plants and animals are mutually dependent on each other. Explain the energy-producing metabolic processes used by plants and animals, and name the products that result. Describe how animals benefit from the products of plant metabolism and how plants benefit from the products of animal metabolism.

Accepted Answer

The answer of Plants and animals are mutually dependent on...

Question 8

Match the following.
A) mesophyll
B) grana
C) stomata
D) stroma
E) thylakoids
-These allow carbon dioxide to enter the leaf and oxygen to exit

Accepted Answer

The answer of Match the following.
A) mesophyll
B) grana
C) stomata
D) stroma
E)...

Question 9

Up until the 1930s it was assumed that the carbohydrates plants produced resulted from the combination of carbon atoms with water, and the oxygen released came from the splitting of the carbon dioxide molecule. You are a scientist testing this hypothesis. You have available to you water labeled with radioactive oxygen atoms and carbon dioxide labeled with radioactive oxygen atoms. Design an experiment to determine whether the oxygen produced during photosynthesis comes from the splitting of carbon dioxide or the splitting of water.

Accepted Answer

The answer of Up until the 1930s it was assumed...

Question 10

Unlike animals, plants are able to obtain ATP through two processes. What are the two processes? Now consider deciduous trees, which drop their leaves in the fall. Do deciduous trees continue to use both these processes during the winter? If not, how do they stay alive during the winter until they grow new leaves in the spring?

Accepted Answer

The answer of Unlike animals, plants are able to obtain...
