Protective tissues:
They protect the plant body by forming an outer layer.
There are two types of protective tissues:
1. Epidermis Simple Tissues
Epidermis tissue covers the entire body of plant.
They protect plant from injury, germs and water loss.
Cells of epidermal tissue form a continuous layer without intercellular spaces.
Stomata are small openings on epidermal layer of leaf and soft part of stem to
facilitate the gaseous exchange and transpiration in plants. Each stomata is
composed of two guard cells which regulate the opening and closing of
stomata.
