• A. transpiration
• B. respiration
• C. reproduction
• D. photosynthesis

Answer 1

The correct option is A transpiration

It occurs due to 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.

Reproduction (or procreation or breeding) is the biological process by which new individual organisms "offspring" are produced from their "parent" or parents. Respiration is the biochemical process in living organisms involving the production of energy. This is done with intake of oxygen and this results in the release of carbon dioxide, water, and ATP (the currency of energy in cells). Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Therefore, the correct answer is option A.
