Answer 2

Answer:

(d)Photosynthesis, respiration and transpiration​

Explanation:

Respiration: As we all know, leaves have tiny pores called stomata, which is used for the exchange of gases.

Photosynthesis: Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close. They regulate carbon dioxide, oxygen, and water vapour exchange with the atmosphere.

Transpiration: Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves.
