Why do plants need a transport system?
- To provide a way of carrying water and ions from the root to the leaves.
- To provide a way of carrying sugars and amino acids from the leaves to other parts of the plant.
- If necessary, from storage organs to the leaves when it is not photosynthesizing.
What tissues of the plant make the transport system?
The two vascular tissues of flowering plants involved in transporting materials around the plant are:-
1. Xylem – transports water and dissolved minerals from the roots up the stem and leaves. (Also xylem gives support to the plant).
2. Phloem – transport food (mainly sugar and amino acids)
