GENERAL KNOWLEDGE

Detailed explanation-1: -Lenticels permit the exchange of gases between the environment and the internal tissue spaces of the organs (stems and some fruits) (Fig. 6.2). They permit the entrance of oxygen and simultaneously the output of carbon dioxide and water vapor. In apple fruit, lenticels account for up to 21% of the transpiration.

Detailed explanation-2: -Leaves of plants have tiny pores called stomata, which is used for the exchange of gases.

Detailed explanation-3: -Lenticels are present on peridermis. Stomata are having guard cells that have presence of chloroplast, so can perform photosynthesis. Lenticels do not have chloroplast and are unable in performing photosynthesis.
