MICROSCOPY UK - MICSCAPE ARTICLE: Stomata |
 | | Stomata are microscopic pores found on the under-surface of leaves and on stems. |
| | The alteration in the size of the stomata occur in response to a variety of the external stimuli such as light, carbon dioxide concentration and water. |
| | The stomata are important for the exchange of gases by diffusion between the outside air and intercellular spaces for respiration and also for the evaporation of water by transpiration. |
