<h3>⇝ <u>Epidermis</u> :</h3>

Protective tissues includes epidermis & cork. Epidermis is basically a simple permanent tissue, protective in function. It forms one-cell-thick covering over all the parts of plant.

<h3>⇝ <u>Characteristics of Epidermis</u> : </h3>
  • Epidermis is formed of living cells, arranged in a single layer.

  • In aerial parts, epidermis is covered with a waterproof and noncellular waxy covering called cuticle.

  • Cells form a continuous layer, but in leaves epidermis has small openings called stomata.

  • Each stoma is guarded by a pair of bean-shaped guard cells which govern opening & closing of stomatal aperture.

<h3>⇝ <u>Functions of Epidermis</u> :</h3>
  • Epidermis protects the underlying tissues from mechanical injury, chemicals & infection.

  • Cuticle of epidermis protects against water loss & desiccation. It checks the rate of transpiration & evaporation and prevents wilting.

  • Stomata in the epidermis of leaves help in gaseous exchange during respiration & photosynthesis.
