Introduction to Plants: Lesson 2 Notes
1. What is photosynthesis?
The process by which plants make food
2. Where does it take place?
Photosynthesis takes place in the chloroplast inside the plant cell. The chlorophyll inside the
cholorplast is the green pigment which absorbs the light energy and it also causes them to appear
green.
3. What are the raw materials?
Carbon dioxide (CO2) , energy from the sun (light energy) and water(H2O)
4. How does photosynthesis happen?
The chlorophyll inside the cholorplast absorbs energy from the sun and uses it to help covnert carbon
dioxide + water into food.
5. What are the byproducts?
After the chlorophyll creates the food for the plant, glucose (sugar) and oxygen (O2) are released. The
oxygen (o2) is released into the environment for animals to breathe in or used by the plant to help
break down the glucose. Oxygen breaking down sugar is a
process called cellular respiration.
The Photosynthesis Formula: Water + Carbon Dioxide +light energy = sugar (glucose) + Oxygen
