Question

Which description properly describes the plant structures involved in photosynthesis? Stomata take in water, sunlight, and carbon dioxide and release oxygen. Xylem transports water, stomata take in carbon dioxide, and chlorophyll absorbs sunlight. Phloem transports water, stomata take in carbon dioxide, and chlorophyll absorbs sunlight. Xylem takes in water, sunlight, and carbon dioxide and releases oxygen.

Answer 1

The correct answer is that "xylem transports water, stomata take in carbon dioxide, and chlorophyll absorbs sunlight." The xylem is a vascular structure in plants that transport water, the phloem is another vascular structure in plants that transport nutrients. The stomata (singular; stoma) is the one responsible for the plants' gas exchange (takes in carbon dioxide, releases oxygen). The chlorophyll is what makes the green pigment of the leaves and mostly because of the presence of chloroplasts, the organelle in plant cells responsible for photosynthesis.
