PHOTOSYNTHESIS
Photosynthesis is howplants make
their food. Just like the water cycle
provides water for life,
photosynthesis provides glucose
for the plant and oxygen for us.
Both cycles show how God’s
creation works together to sustain
life.

STEP 1
Plant cellscontain
chloroplasts.
Chlorophyll, the green
pigment in chloroplasts,
captures and converts
sunlight into chemical
energy.

STEP 2
The energyfrom sunlight
is used to split water
molecules (H₂O) into
oxygen (O₂) and hydrogen
ions (H ).

STEP 3
The carbondioxide (CO₂)
taken in by the plant is
combined with other
organic compounds to
produce glucose through a
series of chemical
reactions.

oxygen
STEP 4
As aresult of photosynthesis,
plants release oxygen (O₂)
into the air.
This is the oxygen we
breathe and is essential for
all living things.
