Plant Life Cycle
How living things grow, live, and die.
The Life Cycle of a Plant
• Seed
• Germination
• Stems and Roots
• Flowers
• Pollination
A life cycle of a Plant
• A life cycle shows how a living thing grows and
changes. Plants exists in different shapes, sizes,
and colors, but most share similar structures.
• While plants life cycles are continuous, the study
of one plant’s life begins with the seed.
What is a seed?
When you look
inside a seed. "You
wear a coat to
keep you from the
cold. Seeds from
flowering plants
have seed coats to
protect them."
Seeds come in all shapes and sizes
Most plants come from
seeds. Inside a seed
is a tiny new plant.
The outside of the
seed has a special
covering called a
seed coat.
What do seeds need to grow?
"What do children need to
grow?" Well plants in
order to grow, plants
need sunlight, water, the
right temperature
conditions, soil, or a
safe place. Plants adapt
in different ways to get
the things they need to
survive.
Germination
• When the seed gets the right amount of water,
warmth, and air it can begin to grow.
• The seeds begins to make a new life with
water, sunlight, and soil.
Stems and Roots
• Stems grow up towards
the light, leaves unfold
to take more sunlight
and produce food
• Roots push down to
anchor the new plants
while they take up
minerals and water from
the soil.
The seed will sprout
• If conditions remain just
right, after a time the
little seed will sprout.
• As the sprout continues
to develop, it will grow
roots, a stem, leaves,
and will form more
seeds.
• At this stage, the life
cycle of the plant begins
again.
It Starts With a Seed
• From a seed, a small
root grows down into
the soil.
• Then, the stem grows up
toward the surface of
the soil.
• Soon, the stem breaks
through the soil.
The Cycle continues
• Later, leaves begin to form on the plant stem.
• Now it is called seedling and can make its own
food.
• Finally, the seedling develops into a plant
which will look like the plant it came from.
Flowers
Many plants produce flowers.
Pollination
• Flowers are pollinated
in various ways– by
bees, birds, and other
animals or even by the
wind.
• At the base if each
flower, seeds are
formed.
• Remember: Bugs, wind,
birds, and other animals
pollinates a flower.
How do seeds travel?
The wind, animals
(bury and or
deposit seeds by
their droppings)
are just some of
the ways seeds
travel.
Can you put these steps in the order we did
them?
• Water the seed.
• Put soil in the cup.
• Put a small drainage hole in the bottom of the
cup.
• Place the seed only about it's own depth in the
soil and cover it up.
• Place the cup in the sun.
