4th Grade Science
What things do
every plant need to
survive?
Basic Needs of Plants
•
•
•
•
Water
Sunlight
Carbon Dioxide
Space to Grow
What are the parts
of a plant?
Plant Structure
• Roots: collect water &
nutrients from the soil
• Stem: carries water &
nutrients from the roots to
the leaves & plant; holds
the plant up
• Leaves: make food for
the plant through
photosynthesis
• Flowers: make fruit and
seeds; responsible for
plant reproduction
• Seeds: opens in ground
and forms a new plant
What do you know
about the life cycle
of a plant?
Plant
Life
Cycle
Plant Life Cycle
• Seed: the seed contains an
embryo that will grow in the
ground
• Germination: the seed begins
to grow roots that will soak up
water and nutrients from the soil
to help the plant grow
• The plant begins to grow a stem
and more roots to help it take in
water and nutrients.
Plant Life Cycle Continued
• Leaves: The leaves begin to grow. They
take in water, sunlight, and carbon dioxide.
They already have chlorophyll (that stuff
that gives them the green color). With all
of those things, the leaves can make food
through what process?
Photosynthesis!
• Plants make
their own food
through the
process called
photosynthesis

Life Cycle Continued
• After filling up on food,
the plant begins to grow
flowers. The flowers may
turn into fruit or may grow
seeds on their own.
• Flowers will be pollinated
so that they can grow
seeds or fruit.
• Some plants grow fruit,
such as apple trees and
pumpkin plants.
Why do plants need to live in
specific environments? For
example, why can’t a cactus
live in Antarctica?
Plant Environments
• Plants must live in
environments that meet their
needs. Each biome supports
the needs of different plants.
• For example, a cactus is
adapted to live in the desert.
Whereas, a cone bearing tree
is adapted to live in colder
climates.
• All living things have
adaptations that help them
survive in the environment
that they live in.
Why does one plant look
like another plant?
Hint: Why do you look like
your parents?
Heredity!
• One plant looks like another because, like
all living things, plants inherit the same
characteristics of their parents.
• The offspring (new seeds) will share the
same characteristics as the adult plant
