Photosynthesis: How a Plant makes Food
Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae (Kingdom Protista).
Plants need only light energy, CO2, and H2O to make sugar and release waste oxgen (O2). The process of photosynthesis takes place in the chloroplasts, specifically using chlorophyll, the green pigment involved in photosynthesis.

Stomata on the Underside of Leaves
Stomata: the "pores" in leaves (and stems) through which CO2 is taken in and O2 is released during photosynthesis. Plants control when stomata are open or closed and the width of the opening (formed by two guard cells that expand and contract to open and close the space between them).
Transpiration: the water that evaporates out of stomata when they are open. This pulls more water and nutrients up to the top of the plant, but causes the plant to lose water and potentially dehydrate.
