Photosynthesis Encyclopedia by: Ashish Setty

How does photosynthesis happen? The process of Photosythesis happens when a plant gets energy from the sun or ATP to produce a type of sugar called glucose from carbon dioxide or CO2 and water or H2O. The plant gets the carbon dioxide from us humans and in return the plant gives us oxygen. Also chloroplast is already in the leafs and that's what makes chlorophyll. The formula for photosynthesis is CO2 + H2O -----> C6H12O6 + O2. The stoma is also a part of the plant which it controls gas exchange in the plant.

The plant is sending out oxygen from the process of Photosynthesis.
A human is breathing carbon dioxide to use to make glucose
The plant is absorbing the sunlight.

How does cellular respiration happen? Cellular respiration is the process in which a human, animal, or plant exchange oxygen and carbon dioxide to form energy. When we exhale carbon dioxide, we inhale oxygen caused by the plants. Our body breaks down the different atoms in the mitochondria and produce energy that used for daily activity such as running. The formula for cellular respiration is the complete opposite of Photosynthesis.

The human is breathing out a harmful waste product called carbon dioxide. The plant collects to make food for itself.
The plant returns the favor and releases oxygen and humans need to survive.
Then this becomes a continues cycle of exchanging carbon dioxide and oxygen.
