Stomata Tissues Leaves Adapted Efficient Gas Exchange Lower

Leaf tissues facilitate gas exchange through stomata in the lower epidermis for CO2 uptake, guard cells controlling stomata, and air spaces in the spongy mesophyll for gas diffusion.

Les tissus foliaires facilitent l'échange de gaz grâce aux stomates de l'épiderme inférieur pour l'entrée de CO2, le contrôle des stomates par les cellules gardes, et les espaces d'air du mésophylle spongieux pour la diffusion des gaz.

Front How are the tissues of leaves adapted for efficient gas exchange?
Back
  • The lower epidermis is full off stomata which let carbon dioxide diffuse into the leaf
  • The opening and closing of stomata is controlled by guard cells in response to environmental conditions
  • The air spaces in the spongy mesophyll tissue increase the rate of diffusion of gases
