1
Transport System in Plants
- Transportation is the process in which substances absorbed or made in one part of a plant are moved to other parts.
- A vascular bundle is formed by xylem and phloem together.
- Xylem transports water and mineral salts from roots to aerial parts of the plant.
2
Xylem: Structure and Function
- Xylem forms a tubular passage for water and mineral salts.
- Xylem tracheids are elongated dead cells with tapering ends and pitted thickened walls.
- Xylem vessels are tube-like dead structures open at both ends and placed one above another.
3
Phloem: Structure and Function
- Phloem transports food manufactured by leaves to all parts of the plant.
- Translocation of solutes refers to the transport of food.
- Glucose produced during photosynthesis is stored as starch and transported as sucrose solution through phloem.
4
