Lower epidermis with guard cells

Principle

The leaf of a deciduous plant consists of various layers. Deep within are cells containing many chloroplasts. The external tissue layer protects the plant against evaporation losses, however, it must also enable an exchange of substances with the ambient air. The leaf needs to take up carbon dioxide and release oxygen and water vapor. There are specialized guard cells in the lower epidermis which make this happen.
