What role do C4 and CAM plants play in photosynthesis under arid conditions?
Correct Answer: C4 and CAM plants enhance carbon fixation efficiency to minimize water loss in arid conditions.
Step 1: Understand that photosynthesis is the process plants use to make food using sunlight, carbon dioxide, and water.
Step 2: Know that in arid (dry) conditions, water is scarce, so plants need to be careful about how much water they lose.
Step 3: Learn that C4 plants have a special way of capturing carbon dioxide that allows them to photosynthesize efficiently even when it's hot and dry.
Step 4: Discover that CAM plants open their stomata (tiny openings on leaves) at night to take in carbon dioxide, which helps them save water during the day when it's hot.
Step 5: Realize that both C4 and CAM plants are adapted to survive in dry environments by being more efficient in using carbon dioxide and minimizing water loss.
