Question
Identify the phloem component which provides mechanical strength to this tissue.

Answer

The various components of phloem are:

  1. Sieve tubes.
  2. Companion cells.
  3. Phloem parenchyma.
  4. Phloem fibres.

Functions are:

  1. Sieve tubes: It conduct food materials prepared in the leaves and greener young stems to all parts of plants.

  2. Companion cells: It helps sieve tubes in conduction of food materials.

  3. Pholem parenchyma: It helps to store food.

  4. Pholem fibres: It provide mechanical strength to plants.
