Answer:
The constituents of phloem are:
- Companion cells: It appears to check the activity of the adjacent sieve element and participates in loading and unloading of the sugar in the sieve element.
- Sieve tubes: These elongated living cells, conveys carbohydrates, chiefly sucrose from leaves to roots and fruits.
- Phloem fibres: They are commercially useful as they posses great pliability and tensile strength.
- Phloem parenchyma: Also known as transfer cells, they are found near the finest branches, ends of sieve tubes and leaf veinlets, functional here in conveying food.
