Photosynthesis
By: Cynthia Perez
Introduction:
In this newsletter you will learn how, when, and where photosynthesis occurs, and why it it is so important to us.
Photosynthesis Definition:
- Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight into chemical energy.
The Three Parts of Photosynthesis
Step 1
Chlorophyll and Carotenoids absorb light energy, water is split into hydrogen and oxygen.
Step 2
The movement of Hydrogen ions across the thylakoids provides energy to produce ATP and NADPH.
Step 3
In the stroma using electrons, carbon enters as carbon dioxide and leaves as sugar.
Importance
Photosynthesis can be considered the ultimate source of life for nearly all plants and animals by providing the source of energy that drives all their metabolic processes.

Chloroplast Description
Chloroplasts are the food producers of the cell. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells.
