Question:
What is the role of xylem tissue?
Answer:
Xylem tissues are specialized for the conduction of water and mineral substances in the plant body.
- Tracheids and vessels form tubular structures to transport water and minerals vertically (unidirectional).
- Xylem parenchyma stores food and helps in the sideways conduction of water.
- Fibres are mainly supportive in function.
