1. PHOTOSYNTHESIS AND CELLULAR RESPIRATION
We will examine the exchange of oxygen and carbon dioxide between living things and the environment.
For: 6th Grade Science Students

2. Key Elements
Chloroplasts - Organelles found only in plant cells that carry out photosynthesis.
Mitochondria - Organelles found in plant and animal cells that carry out cellular respiration.

8. Lesson Summary
Photosynthesis and cellular respiration are related. How?
Photosynthesis occurs in the chloroplast of plant cells.
Cellular respiration occurs in the mitochondria of plant and animal cells.
Whenever you see an arrow in our equations, think “produces”.
Reactants produce products. Remember, what one produces the other one needs. It is a cycle.
