Questions & Step-by-Step Solutions
What role do C4 and CAM pathways play in photosynthesis?
Correct Answer: C4 and CAM pathways help plants photosynthesize efficiently in hot and dry conditions.
Step 1: Understand that photosynthesis is how plants make their food using sunlight, water, and carbon dioxide.
Step 2: Know that some plants live in hot and dry environments where they can lose a lot of water.
Step 3: Learn that C4 and CAM are special pathways that help these plants use water more efficiently.
Step 4: Realize that C4 plants capture carbon dioxide in a way that allows them to keep their stomata (tiny openings) closed during the hottest part of the day, reducing water loss.
Step 5: Understand that CAM plants take in carbon dioxide at night when it's cooler, and store it for use during the day, which also helps them save water.
