Gases for photosynthesis are exchanged through the stomata
|

Energy for cellular reproduction is absorbed through the stomata

|
Carbon dioxide enters the plant through the surface of the leaf for cellular reproduction

Detailed explanation-1: -Terrestrial plants have stomata on the surface of their leaves. A single stomata is surrounded by two guard cells that change shape in response to environmental factors and open or close the stoma.
Detailed explanation-2: -Stomata regulate gas exchange between the plant and environment and control of water loss by changing the size of the stomatal pore. This stomatal movement is affected by several environmental stimuli, such as relative humidity, CO2 concentration, and light intensity.
Detailed explanation-3: -Stomata are more numerous on the lower side of the leaf to prevent transpiration. Transpiration is the loss of water through stomata, so, more stomata are found on the lower surface to prevent excessive loss of water.
Detailed explanation-4: -In leaves, they typically open during the day to favor CO2 diffusion when light is available for photosynthesis, and close at night to limit transpiration and save water.
