What are the constituents of phloem?

Verified Answer

Phloem is a plant tissue responsible for transporting food, especially sugars, from the leaves to other parts of the plant. It is made up of four main components:

  • Sieve tubes – Transport food throughout the plant.

  • Companion cells – Help sieve tubes in the movement of food.

  • Phloem parenchyma – Stores food and assists in transport.

  • Phloem fibres – Provide mechanical strength and support.

Together, these tissues ensure that nutrients produced during photosynthesis reach all parts of the plant for growth and development.
