🌷Photosynthesis and Cellular Respiration~ Natalie🌷 By: Natalie Zulaica

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.

***Carbon Dioxide (CO2), Water (H2O), and Light energy are essential for Photosynthesis to happen.***

Leaves trap energy from the sun, this energy is called light energy.

The process the plant undergoes is the plant absorbs water, oxygen, and light energy. The plant rearranges the molecules and forms a sugar called glucose.

Leaves gather 6 molecules of water and 6 molecules of carbon dioxide.

Leaves use the suns energy to break apart molecules of H2O and CO2.

Leaves reorganize the elements to form glucose (sugar), which is food for the plant.

When the photosynthesis process occurs, here is what's happening: Carbon dioxide, sunlight energy, and water react with each other to create sugar (glucose(C6H12O6)) and Oxygen (O2), which is what we breath in!

Chloroplasts work to convert light energy of the Sun into sugar that can be used by cells. Chlorophyll are molecules found in chloroplasts.

Cellular respiration is the process of which animals take in food and use it to create ATP, a chemical which the cell uses for energy. Usually, this process uses oxygen, and is called aerobic respiration.

Using the chemical formulas... here is the chemical equation for cellular respiration.

Cellular respiration is photosynthesis backwards.

We breathe in oxygen and breathe out carbon dioxide.
