connect photosynthesis and respiration.

Activity: Gizmo - Cell Energy Cycle

Objective

Overview

Materials

● I can explain the cyclical nature of photosynthesis and respiration in the cell.

● Explore the processes of photosynthesis and respiration that occur within plant and animal cells. The cyclical nature of the two processes can be constructed visually, and the simplifed photosynthesis and respiration formulae can be balanced.
