need help with photosynthesis experiments

Question

You have CAM, C3 and C4 plants. You should now investigate photosynthesis using these different plants. The light mentioned is photosynthetically active radition(PAR light), nutrients are nitrogen, phosphorus and minerals they need, carbon is CO2.

You have thought out a few different treatments and planned the experiment.. Equal amounts of algae should be added to all of the following treatments theoretically. Based on the treatments, the following questions must be answered-->

a, What do you think happens in the different treatments 1-5? explain briefly.

b, In which treatment will there be the greatest photosynthesis (*Treatment 1-5)? Why?

c, If you use a CAM plant, C3 plant and a C4 plant in treatments 1, 3, 5 and 6, would the photosynthesis of the different plants differ and if so, how? What do you base the answer on?

Treatment 1: The algae are in a cabinet at + 20 ° C without light but with nutrients and carbon

Treatment 2: The algae are under light conditions (PAR) which are much higher than what the algae are used to but have + 20 ° C and nutrition + carbon

Treatment 3: The algae have limited with carbon. They have + 20 ° C and nutrition and adequate light (PAR)

Treatment 4: The algae have plenty of nutrients + carbon and + 46 ° C, and enough light (PAR)

Treatment 5: The algae stand in limited light (PAR), with plenty of nutrients + a lot of carbon and + 22 ° C

Treatment 6: (*Just question "c" ) The plants have poor water, but they have nutrition + carbon and good with light (PAR).

Answer 1

a.Treatment 1: The algae will not undergo photosynthesis due to the lack of light.

Treatment 2: The algae will undergo photosynthesis at a high rate due to the high light intensity and presence of nutrients and carbon.

Treatment 3: The algae will undergo photosynthesis at a limited rate due to the limited amount of carbon, but the presence of adequate light and nutrients will still allow for some photosynthesis.

Treatment 4: The algae will undergo photosynthesis at a high rate due to the high temperature, abundance of nutrients and carbon, and sufficient light.

Treatment 5: The algae will undergo photosynthesis at a limited rate due to the limited light, but the abundance of nutrients and carbon will still allow for some photosynthesis.

Treatment 6: (*Answering c only) The photosynthesis rate of the different plants would differ due to their different photosynthetic pathways. CAM plants would likely have a higher photosynthesis rate than C3 and C4 plants under these conditions, as they are adapted to water-limited environments and can conserve water by opening stomata at night to take in CO2 and storing it as malate. C3 and C4 plants would likely have lower photosynthesis rates under these conditions due to their higher water requirements.

b. Treatment 4 is likely to have the greatest photosynthesis rate, as it has the combination of high temperature, abundance of nutrients and carbon, and sufficient light, which are optimal conditions for photosynthesis.
