Why is transport needed in life processes?
Answer and explanation
Correct answer: To carry substances to different body parts
Transport is necessary because essential materials and wastes are not always located where they are needed. In animals, blood carries oxygen, digested nutrients, hormones, and wastes between organs. In plants, xylem transports water and minerals, while phloem distributes food. Therefore option A expresses the governing purpose. The other options would prevent, rather than support, cellular activities and do not describe transport.
