Iteru [2.4K]

<h3>Answer:</h3>

Stomata

<h3>Explanation:</h3>

Photosynthesis refers to the process that takes place in green plants and some algae.
During the process, water and carbon dioxide are converted to nutrients or organic compounds using energy from sunlight.
The process takes place in the chloroplast on the leaves of green plants.
The water used during photosynthesis comes from the soil and then transported by xylem tissue to the leaves where the process takes place.
Carbon dioxide enters the leaves through the stomata which are the sites for gaseous exchange.
Sunlight is trapped by green pigments on the leaves known as chlorophyll.
