How do multicellular organisms exchange gases
WebFeb 18, 2024 · A reason is that multicellular organisms need special organs for exchange of gases with the environment because of prokaryotic cells found in the body. The cells are not in contact with the environment and therefore diffusion would not work in the exchange of gases. The organs in the body therefore serve this purpose. WebThe mass flow systems of plants comprise xylem and phloem. Xylem transports water and mineral ions from the roots to aerial plant parts, whereas phloem transports products …
