Question

write any three differences between xylem and phloem

Answer 1

XYLEM

1) It conducts water and minerals .

2) Conduction is mostly unidirectional , I.e., from roots to apical parts of the plant .

3) Conducting channels or tracheary elements are Tracheids and vessels .

PHLOEM

1) It conducts organic solutes or food materials .

2) In it conducting may be bidirectional , I.e., from leaves to storage organs or growing parts or from storage organs to growing parts of plant .

3) Conducting channels are sieve tubes .

Answer 2

Plants have two different types of transport tissue. Xylem transports water and solutes from the roots to the leaves, phloem transports food from the leaves to the rest of the plant. Transpiration is the process by which water evaporates from the leaves, which results in more water being drawn up from the roots. Plants have adaptations to reduce excessive water loss.
Xylem and phloem
Plants have transport systems to move food, water and minerals around. These systems use continuous tubes called xylem and phloem.
Xylem
Xylem vessels are involved in the movement of water through a plant from its roots to its leaves. Water:
Is absorbed from the soil through root hair cells
Is transported through the xylem vessels up the stem to the leaves
Evaporates from the leaves (transpiration)
Phloem
Phloem vessels are involved in translocation. This is the movement of food substances from the stems to growing tissues and storage tissues.

Root - xylem and phloem in the centre of the root to withstand stretching forces.
