Answer 1

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Plant leaves have a special structure, a bean shaped part in leaf, known as the stomata. The role of stomata is seemingly similar to that of a human nose. Stomata plays a key role in the exchange of gases between the plant and atmosphere. It also has a major role in transpiration which is the process through which the excess water is released through stomata in the form of vapour.
