Question

C4 and CAM photosynthesis evolved because

A. Even though they require more ATP, they prevent Rubisco from binding to the wrong molecule
B. They are more efficient in their production of ATP, so plants can grow faster, making them the preferred way to photosynthesize for all plants
C. They allow oxygen (O2) to be used to create sugar, in addition to CO2
D. They do not use Rubio, which does not operate well in high heat

Answer 1

C4 and CAM photosynthesis have evolved as adaptations to different environmental conditions. C4 photosynthesis is more efficient in terms of water use and is favored in drier regions. CAM photosynthesis allows plants to conserve water during hot daytime temperatures.

Step-by-step explanation:

C4 and CAM photosynthesis evolved to help plants adapt to different environmental conditions. C4 photosynthesis is more efficient in terms of water use and is favored in drier regions. It allows plants to keep their stomata open for CO2 capture while conserving water. On the other hand, CAM photosynthesis is selected in evolution to allow plants to conserve water during hot daytime temperatures. Stomata in CAM plants close during the day to minimize water loss and open at night to take up CO2. CO2 is fixed and stored as malic acid during the night and then released and used for photosynthesis during the day.
