Epidermal Tissue System in Plants

The epidermal tissue system is the outermost layer of the primary plant body, protecting the plant from water loss, pathogens, and mechanical damage.
It is composed of epidermal cells, trichomes, and root hairs.

Components of the Epidermal Tissue System

Epidermal cells: tightly packed, flat, and rectangular cells that form the outer layer of the plant.
Trichomes: hair-like structures that provide defense against herbivores and reduce water loss.
Root hairs: thin, hair-like extensions of root epidermal cells that increase the surface area for water and nutrient absorption.

Functions of Trichomes

Provide defense against herbivores and insects.
Reduce water loss by creating a barrier to water evaporation.
Shade the surface of the plant, reducing temperature and transpiration.

Role of Root Hairs

Increase the surface area for water and nutrient absorption, enhancing the plant's ability to absorb nutrients.
Improve the plant's ability to anchor itself in the soil.

Ground Tissue System in Plants

The ground tissue system is composed of parenchyma, collenchyma, and sclerenchyma cells.
It performs functions such as storage, support, and photosynthesis.
It is the tissue system that provides the plant's internal structure and supports the plant's growth and development.
