Why is phloem considered necessary for food transport in plants?
Answer and explanation
Correct answer: Because it carries food made in leaves to other parts
Leaves are the main sites of photosynthesis, so they produce sugars such as sucrose. These dissolved organic substances must be distributed to roots, stems, growing buds, fruits, and storage organs. Phloem sieve tubes and associated cells transport this food from source tissues to sink tissues, and movement can occur in different directions according to demand. Hence A is correct. Xylem carries water, stomata exchange gases, and urine formation is an animal function.
