Question
Describe the transport system in plants in detail.
✓

Answer

→ Think of xylem as the plant's plumbing system for water and minerals.
→ Xylem tissue transports water and dissolved minerals from the roots to the stems and leaves.
→  The flow in the xylem is primarily unidirectional (upwards from the roots).
→ Now, phloem is like the plant's food delivery service.
→ Phloem tissue transports sugars (produced during photosynthesis) from the leaves to other parts of the plant.
→ The flow in the phloem can be bidirectional, meaning it can move sugars both upwards and downwards to reach all parts of the plant.
