EVERYDAY SCIENCE

Detailed explanation-1: -Carbon dioxide and oxygen cannot pass through the cuticle, but move in and out of leaves through openings called stomata (stoma = “hole"). Guard cells control the opening and closing of stomata. When stomata are open to allow gases to cross the leaf surface, the plant loses water vapor to the atmosphere.

Detailed explanation-2: -Carbon dioxide enters the leaves through tiny pores present on the surface of the leaves called stomata. Note: Photosynthesis occurs during the day time. Thu stomata are open mostly throughout the day for supplying the carbon dioxide to the plants. Respiration occurs throughout day and night.

Detailed explanation-3: -Stomata are the small pores present on the leaves of the plant. Carbon dioxide enters the plants through these openings.

Detailed explanation-4: -Carbon dioxide from the air enters the leaf through the stomata.

Detailed explanation-5: -Final answer: Carbon dioxide enters the leaves of the plants through stomata and helps in photosynthesis.
