Crassulacean acid metabolism (CAM) is a method of photosynthesis used by some plants that live in dry environments. A plant using CAM photosynthesis closes its stomata during the day but opens them at night to collect and store carbon dioxide. During the
day, the carbon dioxide is transported to chloroplasts photosynthesis can take place.
Why is CAM photosynthesis beneficial to plants that live in dry environments?
OA. It ensures that water absorbed by the roots and transported to the leaves is used for photosynthesis rather than being
released to the air.
OB. It prevents the movement of water from the roots to the leaves during the day, which ensures that the leaves can conduct
photosynthesis
OC. It allows the leaves to take up water during the night and transport it to the roots, where it can be stored for
photosynthesis
OD. It blocks water from being absorbed by the leaves during the day, which ensures that the process of photosynthesis will
not be disrupted by water.
