2. Gizmo Warm-up
The Cell Energy Cycle Gizmo™ illustrates two
processes that are essential to life: photosynthesis
and cellular respiration
Although both of these processes involve a series of
complex steps, the inputs and outputs of each process
are four relatively simple molecules.

Photosynthesis
Get the Gizmo ready :
 If necessary, click Reset .
 Check that the PHOTOSYNTHESIS tab is
selected. Check that Description is turned on.

Introduction: Photosynthesis occurs in the chloroplast , an organelle found in plant and algae
cells. Within the chloroplast, a green pigment called chlorophyll converts the radiant energy of
sunlight into chemical energy that the plant can use.
Question: What are the inputs and outputs of photosynthesis?
1. Predict : Of the molecules shown on the MOLECULES pane, which do you think are inputs
(ingredients) in photosynthesis? Which do you think are outputs?
