Question

What are the constituent of xylem and phloem?

Answer 1

The constituents of xylem are --
1> Xylem Parenchyma
2> Xylem Fibres
3> Tracheids
4> Vessels
 
the constituents of phloem are --
1> Sieve Tubes
2> Companion Cells
3> Phloem Fibres
4> Phloem Parenchyma

Answer 2

Xylem and phloem are two vascular tissues which play a role in transportation of food and water. These are the constituents of phloem and xylem tissues.

- Xylem tissues has  

- Tracheids

- Vessels

- Xylem parenchyma  

- Xylem fibers  

In xylem tissues tracheids and vessels transport water from roots to other parts of the plants.  

Phloem tissue has

- Sieve tube  

- Companion cells  

- Phloem parenchyma  

- Phloem fibers  

In phloem tissue sieve tube and companion cells transport food from leaf to other parts of the plant.
