• Photosynthesis is the process by which light
energy is utilized to convert carbon dioxide
and water into food to be used by plants.
– Oxygen is released into the air during the
process. (O2)
– Light or solar energy is captured by chlorophyll
(CHLOR-oh-phil), the green pigment in leaves.
– It is then converted into chemical energy which is
stored as starch or sugar.
– These starches and sugars are stored in roots,
stems and fruits. They are available to the plant
as food or fuel.

• Plants can get their energy from the sun
by just sitting there, we have to go search
for it, hunt, etc. We didn’t we evolve to be
green and get our energy from the sun.

• Answer! Because photosynthesis only
produces a small amount of energy.
– We need lots of sugar to run, jump, and live our
very busy and active lives.
