What are the characteristics of epidermal tissue explained?

Epidermal tissue has the following characteristics.
Epidermal tissue has the following characteristics.

  1. Generally epidermal consists of one layer of cells. An example is the velamen cells in the orchid root.
  2. Epidermal having cells that are tightly arranged without intercellular space.
  3. The shape of cells varies, for example tubular shape on dicot leaf leaves, elongated shape on epidermal cells of monocot leaf leaves and hexagonal shape on Aloe cristata leaf strands.
  4. Cells epidermal have many vacuoles and protoplasts which store various metabolic products.
  5. The thickness of the epidermal cell wall varies. The seeds and leaves of coniferous plants have very thick cell walls.
  6. There are epidermal cell walls that contain lignin, cuticles, and pectin. In plants that live in dry habitats, epidermal cell walls have thick cuticles. On the cuticle surface there are wax deposits, causing the leaves and fruit to look shiny. The waxy coating is very important to keep the organ moist.
  7. Epidermal initial cells can partially develop and modify into other additional devices called derivatives, epidermis, such as stomata (leaf mouths), trichomes (hairs), emergencies, spines (thorns), germ cells (germ cells) silica), velamen, and litokis.
