What are the constituents of phloem?

Phloem is the food conducting tissue in plants. It is made up of four components: 

(i) Sieve tubes 

(ii) Companion cells 

(iii) Phloem parenchyma 

(iv) Phloem fibres 

The constituents of phloem tissue are:

(i) Sieve tubes (tubular living cells with perforated end walls)

(ii) Companion cell (living cells)

(iii) Phloem parenchyma (living cells)

(iv) Phloem fibres (non-living and sclerenchyma cells)

Phloem consists of sieve tubes, companion cells, phloem fibres and phloem parenchyma.

The constituents of phloem are:
`rarr`Sieve tubes
`rarr`Companion cells
`rarr` Phloem parenchyma
`rarr` Phloem fibres

Phloem is a complex tissue of the angiosperm plants. It serves as a conducting tissue and is made up of four types of elements: (i) Sieve tube, (ii) Companion cells, (iii) Phloem fibres (bast fibres), and (iv) Phloem parenchyma.
