Photosynthesis happens when a plant gets energy from the sun or ATP and the hydrogen and oxygen from water go up the xylem. The molecules enter the leaves and are separated by chlorophyll. Then the plant releases oxygen into the air.
Cellular respiration happens all the time. Any living thing has cellular respiration, and what happens is that the living thing breathes in oxygen, and then the cells convert sugar into carbon dioxide and water, which also releases ATP.
Plants use light energy to convert it into chemical energy that fuels that living organism.
A plant uses light energy to produce glucose from carbon dioxide and water.
Plants breathe in carbon dioxide while we breathe out carbon dioxide, so it's a good relationship.
Stomp is any of the pores in the leaf or stem of a plant which allows the movement of gases.
The plant separates molecules with chlorophyll.
Chloroplasts separates the light energy from the sun into sugars.
