The main functions of stomata are:
- Gaseous exchange- Stomatal opening and closure help in the gaseous exchange between the plant and surrounding.
- It helps in transpiration and removal of excess water in the form of water vapour.
- Stomatal closure at night prevents water from escaping through pores.
- It maintains the moisture balance according to weather by opening and closing.
- Stomata facilitate carbon dioxide uptake and release of oxygen during the process of photosynthesis.
