Answer 1

Answer:

All plant leaves need to “breathe”. The exchange of atmospheric gases is essential to photosynthesis, the process by which plants use sunlight to convert carbon dioxide and water into oxygen and fuel (carbohydrates). Leaves have special pores called stomata that make gas exchange possible while helping to control the loss of water.

Guard cells swell, through the process of osmosis, to allow opening of the stomata (for CO2 to enter and excess O2 and H2O to leave), and they shrink in order to force the stomata shut (either partially or completely) to prevent dehydration.

In order  Plants must also permit the movement of water from the roots to the leaves through the process of evaporation/transpiration in order to make water available to the cells for photosynthesis.
