Epidermis:

The outermost layer of cells on the primary plant body includes seed, fruit, leaves, stem, and root. It is absent on the root cap.

Overview:

• Epidermis
• Types of Epidermis
• Root Cap
• Epiblema

Types of Epidermis:

1.      Shoot Epidermis:

Arise from the outermost cell of the apical meristem.

2.      Root Epidermis:

Arise from the epidermal cell of roots.

Root cap:

The outermost layer of the cortex is called the root cap.

Epiblema:

The abnormal epidermis that is present on the root hair is called epiblema.

3.      Multiple Epidermis:

The epidermis divides periclinal and forms many layers of epidermis called multiple epidermis.

4.      Hypodermis:

The sub-epidermal layer resembles multiple epidermis.

5.      Lithocyst:

Multiple epidermis inner layer expands more than the outer layer and has the largest mass of cells called lithocyst.

6.      Cystolith:

Lithocysts produce a classified body called cystolith.
