Why do some submerged aquatic plants use CAM photosynthesis?

Describe in detail photosynthesis as a redox process. What gets oxidized? What gets reduced?

What special adaptation has evolved in CAM plants such as cacti and stonecrops that allows CO2 fixation and the Calvin cycle to occur in the same cell, but still occur separately? Briefly describe how this separation of events works.

What is the waste product is generated in plants during photosynthesis?

What is the source of carbon for making glucose in photosynthesis?

if mutation makes photosystem I function less efficiently, which of the following is most directly affected? rate of ATP sythesis by ATP sythase in cholorplast? Rate at which protons are transported into thylakoid? Rate at whinch NADPH is produce? a mount of O2 produced?

Is the water also used in the phototsynthesis in the leaves, like are some of the H ions used in the Electron transport chain? Or is it purely transpired?

How does light color affect the rate of photosynthesis?  Why does the color of light matter?      Clear Red Green Blue Number of Bubbles  (1 Min) 6 12 6 15

How is the photic energy absorbed by chlorophyll transfered to ATP molecules in photophosphorylation? How will be the resulting ATP used?

Which of the following best summarizes the strategy used by CAM plants, which live in hot and dry climates, in order to conserve water? O These plants use a different electron donor so that they won't consume water O These plants keep stomata closed day and night to avoid evaporation O These plants collect carbon dioxide at night, but then use the carbon dioxide during the day O These plants are heterotrophs, so they do not need to rely on light reactions that consume water
