What is the advantage to a cell of having two photosystems that work together?

What do organisms need along with chloroplasts to perform photosynthesis? (Choose all that apply.) Sunlight Carbon dioxide OGlucose Water

Chloroplasts contain chlorophyll and carotenoids. Chlorophyll directly absorbs light for use in photosynthesis. Carotenoids absorb light and transfer the energy from light to chlorophyll. The efficiency of photosynthesis varies with the wavelengths of the light that illuminates the chloroplasts. In an experiment to study the relationship between the incoming light wavelengths and the chemical reactions of photosynthesis using a species of green algae, a researcher labeled the CO2 supply to the algae with 14C, and the H2O with 18O. Which of the following results is expected? More 14C is found in the algae when it is illuminated by green light than when it is illuminated by blue-violet and red light. More 18O is found in the algae when it is illuminated by green light than when it is illuminated by blue-violet and red light. More 14C is found in the algae when it is illuminated by blue-violet and red light than when it is illuminated by green light. More 18O is found in the algae when…

How are the processes of cellular respiration and photosynthesis related? The carbon molecules in glucose are converted to what molecule during respiration? What happens to the carbon dioxide molecules plants use in photosynthesis? Do plants have both chloroplasts and mitochondria? Why would this be?

Which of the following shows the path of electron flow during photosynthesis?   Question 5 options:   photosystem II → cyt b6f → photosystem I   cyt b6f → photosystem I → photosystem II   photosystem I → photosystem II → cyt b6f   cyt b6f → photosystem II → photosystem I   photosystem I → cty b6f → photosystem II

To understand photosynthesis, it is important to first understand the larger picture of what molecules the cell uses and generates and how the different molecules cycle between different reactions. The diagram shows a broad overview of the two stages of photosynthesis. Select the label that best corresponds to the lettered blanks in the diagram below.   The parentheses represent the choices for each label on the graph.   A. (ADP, ATP, O2, Co2) B. (NADPH, Sugars, NADP+, Sunlight) C. (H2O, Sugars, O2, Co2) D. (Sugars, Co2, O2)
