Plants
Produce
Food
Every organism on Earth
needs energy to live and grow.
The primary
source of all
life energy on
Earth’s is the
Sun.
But animals can’t eat
sunlight.
Animals can only get energy by
eating
(consuming)
other organisms
(plants or animals).
Animals are consumers.

Only green plants can

Plants are producers.
They make food.
Only plants
can make
food.
Plants
make
food in
their
leaves.
A green material in
leaves called
chlorophyll
(klor oh fil)
turns light energy
from the sun into
chemical energy
(sugar).
Producers convert
sunlight energy into a
chemical energy
(glucose; sugar; food)
that animals must
have to live.
Sugar made in the leaves
moves through tubes to
other parts of the plant.

Plants store the food they
make in different ways.

Plant leaves must
have three things
in order to make food.
Plants must have three things
in order to make food.

Plants must have

Plants must have
carbon dioxide
in order to make food.
CO2 (carbon dioxide)
is a gas that makes up about
1% of Earth’s atmosphere.

Plants get the light
they need from the
Sun.
Plants get the CO2,
carbon dioxide, they
need from the air.
Plants get the
water they need
from soil with
their roots.
Water goes
through tubes
in the stem to
get to the
leaves.
The process of plants
turning sunlight energy,
CO2, and water into

The process of plants
turning sunlight energy,
CO2, and water into
chemical energy
(food, sugar) is called
photosynthesis

photosynthesis
Photo means “light”

Synthesis mean “to put together.”
Photosynthesis mean “to put it

Photosynthesis mean
“to put together with light.”
Plants “put food together” using
light energy in the process called
photosynthesis.
Plants take (CO2)
carbon dioxide
into their leaves
and use it during
photosynthesis.
CO2
Plants release
(throw away)
oxygen as a
waste product as
they make food.
oxygen
Plants release
(throw away)
oxygen as a
waste product
as they make
food.
Oxygen is a gas that
makes up 21% of the air.
Plants can’t live
without CO2 and must
release oxygen.
Animals can’t live
without oxygen and
must release CO2.
This is a very important
balance for life on Earth.
Now, let’s see how much
you remember about
producers
and
photosynthesis.
Which type of organisms
must eat other organisms?
Consumers (animals)
must eat other organisms.
Which type of organisms
can make food?
Only
producers (plants)
can make food.
What waste gas is
released by plants
as they make food?
?
Oxygen is the
waste gas released by
plants as they make food.
oxygen
Review:
What waste gas is
released by animals
as they live
and breathe?
Review:
CO2
carbon dioxide
is the waste gas
released by animals
as they live and
breathe.
CO2
What gas is
needed by plants
as they make
food?
?
CO2 gas is
needed by plants
as they make food.
CO2
Carbon dioxide
What is the name of the process
in which plants (producers)
make food?
Photosynthesis
is the process in which
plants make food.
Review:
In what part of
the plant is
sunlight turned
into food?
(glucose; sugar)
Leaves are the part of
the plant where food is made
during photosynthesis.
One leaf
Three leaves
What is the name for the
energy chemical that
plants and animals
need to live and grow?
What is the name for the
energy chemical that
plants and animals
need to live and grow?
Hint:
Plants make it
in their leaves
from sunlight,
CO2 and water.
Sugar or glucose is the
name for the energy chemical
that plants and animals need
to live and grow.
What is the name of the
green substance that
converts sunlight energy to
make sugar in the leaves of
plants?
Chlorophyll is the
green substance that
converts light into sugar in
the leaves of plants.
What three things do plants
need in order to make food
during photosynthesis?

Plants must have these
three things in order to
make food in photosynthesis.

are produced by plants
during photosynthesis.

Plants move materials through a
system of tubes.
Xylem (zy lem)
tubes carry
water and
nutrients
from roots to
the leaves.
Phloem (FLO em)
are the tubes that carry
sap (sugar and water)
from leaves to every
part of the plant.
Organisms have system
of tubes
to transport materials.
