Stomata regulates transpiration and CO₂ intake by changing its size according to environmental signals.
Explanation:
- Stomata plays a vital role in plant development by regulating the exchange of gas with the atmosphere and controlling transpiration.
- Stomata regulates transpiration and CO₂ intake by changing its size according to environmental signals.
- In optimum conditions, the stomata are wide open, allowing a gas exchange with the atmosphere.
- Guard cells are responsible for changing the size of the pore, expanding or effectively contracting the opening and closing of the stomata.
- For stomata opening, water is rushed into the cells of the guard due to osmosis, which depends on the concentration of potassium in the cells.
