provide Hypothesis and conclusion linking your observed trend with the functioning of the light reactions in plants. How does the amount of light received affect the light reactions of photosynthesis?
SUBJECT: GENERAL BIOLOGY 1 / CAM and C4 Photosynthesis
Plant adaptation is varied among all organisms present on Earth’s fauna. Also,
we can’t deny the fact that as time goes by, the amount of carbon rises making it
more complicated for the rest of organisms to adapt and survive.
In relation to their specialized features, predict how C4 and CAM plants will each respond to a doubling
of the concentration of CO2 in the atmosphere.
Based on the graph below, what can
you infer?
Absorption and Action Spectra
400
500
600
700
Wavelength of light (nm)
photosynthesis is most active between 400-
475. That is why plants are green
photosynthesis is most active between 450
-550. That is why plants are green
photosynthesis is most active between 600-
700. That is why plants are green
both a and c are correct
There is not enough evidence in the graph
to infer any of the above

- Which of the following is a correct step in the light-dependent reactions of the Z system? a. Light is absorbed at P700, and electrons flow through a pathway to NADP+, the final acceptor of the linear pathway. b. Electrons flow from photosystem II to water. c. NADP+ is oxidized to NADPH as it accepts electrons. d. Water is degraded to activate P680. e. Electrons pass through a thylakoid membrane to create energy to pump H+ through the cytochrome complex.arrow_forwardIt is possible that you recently discovered a new species of plant in the Amazon Rainforest. It is surprising that this plant can survive with limited sunlight in the diverse ecosystem of the Amazon. The plants unique quality has the potential to have a significant impact on both the realm of ecology and diverse sectors. Your main goal is now to investigate the efficiency of photosynthesis in this plant, specifically analyzing the structure of the chloroplasts and the distribution of pigments (chlorophyll and carotenoids) utilizing microscopy techniques. Both conventional fluorescence microscopy (FM) and CSM possess the capability to identify the distribution of pigments, specifically chlorophyll and carotenoids. How does the process of stimulating fluorescence and detecting fluorescence differ between these two microscopy techniques? Given these disparities, which approach is more likely to yield superior outcomes for your research? Could you please explain, taking into consideration…arrow_forwardIt is possible that you recently discovered a new species of plant in the Amazon Rainforest.

She filled two test tubes with distilled water and placed a piece of Elodea in each of the tubes. She added a drop of phenol red, which turns red in a basic solution and yellow in an acidic solution. She blew in each tube before placing the volumeters on the top of the tube.
