Pavement cells

Pavement cells are a cell type found in the outmost epidermal layer of plants. They are simple cells with no specialized function. Together, the main purpose of these cells is to form a protective layer for the more specialized cells below. This layer helps decrease water loss, maintain an internal temperature, keep the inner cells in place, and resist the intrusion of any outside material. They also separate stomata apart from each other as stomata have at least one pavement cell between each other.
