Understanding Xylem and Phloem – Simple Explanation
Plants transport water, nutrients, and sugars through specialised tissues known as xylem and phloem. While both play vital roles in plant survival, they differ in structure, function, and the substances they transport. Understanding the difference between xylem and phloem helps explain how plants grow and stay healthy.
What is Xylem?
Xylem is the plant tissue responsible for transporting water and minerals absorbed by the roots to the rest of the plant. It mainly moves substances upward from roots to leaves.
Structure of Xylem:
Tracheids and vessel elements (transport cells)
Lignified walls for support and strength
Non-living tissue at maturity
What is Phloem?
Phloem is the tissue responsible for transporting food (sugars) produced by photosynthesis from the leaves to all other parts of the plant. Phloem transport can occur in both upward and downward directions.
Structure of Phloem:
Consists of living cells (sieve tubes and companion cells)
Flexible transport direction (upward and downward)
Plays a role in nutrient distribution

FAQs on Difference Between Xylem and Phloem: NEET
1. What is the primary difference between xylem and phloem?
Xylem transports water and minerals upwards; phloem transports sugars and nutrients throughout the plant.
2. Is xylem living or non-living tissue?
Xylem is non-living tissue at maturity.
3. Can phloem transport nutrients both ways?
Yes, phloem moves sugars and nutrients both upwards and downwards.
4. What types of cells form xylem?
Xylem mainly consists of vessels, tracheids, and fibers.
5. Which tissue provides structural support to plants?
Xylem provides structural support due to its thick, lignified walls.
6. Do phloem cells remain alive?
Yes, phloem cells remain alive even after maturity.
7. Does phloem need energy to transport substances?
Yes, phloem transport requires energy (ATP).
8. What substances do xylem cells transport?
Xylem cells transport mainly water and dissolved minerals.
9. Is phloem tissue found in all plants?
Phloem tissue is found in all vascular plants.
10. Why is understanding xylem and phloem important?
Understanding xylem and phloem helps explain how plants grow, survive, and distribute essential nutrients and water throughout their systems.
