How plants grow
Created by Miss Castillo
Can you think of what a plant
might need in order to flourish
and grow?
What plants need
 Plants are living
things and they need
some things in order
to survive.
 Plants need water, air,
soil, and light so that
they can grow and
thrive.
Plant Parts
 All plants have the
same parts.
 The roots are found
underground.
 The stem connects
the leaves and roots
and gives some
support to the plant
above ground.
 Leaves grow out of
the stem.
The stem carries
water from the roots
to other plant parts.
The leaves take in
the air and light a
plant needs.
Roots hold a plant in the
ground. They help take in
minerals and water from the
soil.
How does the water in the soil
get to a plant’s leaves?
Leaf shapes
 Leaves help a plant
get the air and light
that it needs to
survive.
 Leaves come in
different shapes and
sizes.

branches of a tree?

indoor plant?
Growing plants from seeds
What are seeds?
 The seed is the first
stage of growth for
many plants.
 Seeds look different
than the plants they
come from, but they
will eventually grow
into that very same
type of plant.
What seeds need
 Seeds need water in order to grow.
 Once a small plant has broken out of a seed, it has
germinated.
 When the seed sprouts, roots begin to grow from it.
 When a young plant, or seedling appears, it begins to
form parts that it will need as an adult.
Some plants make seeds
 Two groups of plants
grow seeds.
 One group is the
plants grow flowers.
 The second group is
the plants that have
cones.
 Some plants can be
grown from plant
parts.
 What do both plants and seeds
need in order to grow?
Seed Parts
Seedling: A seedling
lives inside of every
seed.
 Seeds come in
different shapes,
sizes, and colors; but
they all have the
same parts.
Stored food: Most of the inside
of the seed contains stored
food. The plant uses this food
to grow when it begins to
sprout.
Seed coat:
Protects the
plant inside
of the seed.
How seeds are spread
 Seeds are scattered
and moved to new
places.
 Some are shot out of
adult plants like
cannonballs!
 Others are spread by
air, water, and
animals.
QUIZ TIME!!!
 What is a seedling?
 What are some ways plants make new plants?
 Describe some ways an animal can carry a seed
from one place to another.
How Plants Make Food
Making Food
 Plants can make their
own food.
 This food-making
process is called
photosynthesis.
 Chlorophyll helps plants
get their green color and
it helps plants use
energy from the sun to
make food.
 Plants also need light,
water, and carbon
dioxide to make food.
Chlorophyll
During photosynthesis, a plant takes in
sunlight, water, and carbon dioxide. The
chlorophyll in the leaves lets the plant use
all of these elements to make food. The
plant makes sugar and then gives off
oxygen.
How Plants Use Food
 Plants use some food
to grow larger.
 Some food is used to
make seeds.
 Some store food in
their roots and stems
to save it for later.
 Some plants store
sugar in fruit. This
makes for a delicious
snack for us!
QUIZ TIME!!!
 What happens during photosynthesis?
 Why gives plants their green color?
 How does chlorophyll help in photosynthesis?
 How does the photosynthesis process help
make food that people and animals can eat too?
