Cellular Respiration & Photosynthesis Overview
1. Define cellular respiration.A process that releases energy from food, such as the simple sugar glucose, when there is oxygen present.
2. Define photosynthesis.
Photosynthesis is the process by which photosynthetic organisms convert solar energy into chemical energy stored in sugars.

3. Name several organisms that undergo cellular respiration
Nearly all living things undergo cellular respiration*.
Exceptions include a few microscopic marine animals (Loricifera) and some bacteria.
4. Name several photosynthetic organisms.Trees Algae Cyanobacteria
