Epidermal Tissues - GCSE Biology Definition

Epidermal tissues are the outer layers of cells that cover the surfaces of plants and animals, acting like a protective skin. In plants, they cover leaves, stems, and roots, helping to protect them from damage and disease. They also help to reduce water loss. In animals, like humans, the epidermal tissues form the outermost layer of the skin, shielding the body from harmful environmental factors, pathogens, and dehydration. In both plants and animals, these tissues are crucial for protection and maintaining the right balance of substances inside.
