Q. 3. What are the components of the transport system in highly organised plants?
In highly organised plants the transport system consists of the following two components.
(i) Xylem: The xylem consists of a network of vessels and elongated cells called tracheids. The xylem tissues transport the water and other minerals absorbed from the soil by the roots to different parts of the plant.
(ii) Phloem: The Phloem tissue transports the soluble organic compounds (food) synthesized during photosynthesis from the leaves to other parts of the plant.
