 Stomata are epidermal structures formed by two guard cells located on leaf pores. The other epidermal structure is an impenetrable waxy layer. Consequently, stomata have important roles in regulating the flow of gases (like CO2 and O2), hormones (like ABA), and water out of and into the leaves. As a result, they also influence plant productivity and resistance towards drought and flooding. Stomata are also the point of entry for pathogenic bacteria, so they also have a role in resistance toward biotic stresses. Therefore it is reasonable to suggest that stomata have significant contributions toward improved plant productivity. |
