Basic presentation of the parts of a plant and of the life cycle of plants. Pitched at about the 2nd, 3rd or 4th grade level. Lots of descriptive pictures and diagrams.

1. Parts of a Plant
and
The Life Cycle of a
Plant

2. Parts of a
Plant

3. Parts of a Plant
• Roots hold the plant in the soil so it doesn’t blow away.
They also take in water.

4. Parts of a Plant
• The stem holds up the plant and carries
water from the roots to the leaves.

5. Parts of a Plant
• The leaves use light from the Sun, carbon
dioxide from the air and the water taken in by
the roots to make food for the plant.

6. Parts of a Plant
• The plant’s flowers make seeds.

7. • Dandelion flower and seeds.

8. Parts of a Seed
• Seed Coat– protects seed • Embryo (baby plant)
—beginning leaves,
• Cotyledon—stored food stem and root
Embryo
—baby
plant

9. Seeds
• Seeds are formed in the center part of
the flower or in the fruit. Fruits come
from flowers.
• Seeds come in many shapes and sizes.
• Plants grow from seeds.

10. If a seed receives water and gets warm, the
baby plant (embryo) inside it starts to grow.
The process of a baby plant beginning
to grow is called germination. We say
the seed germinates or sprouts.
The first part of the
plant we see
pushing its way out
of the seed coat is
the root.

11. Here we see
pictures of a
bean seed and
a corn seed
germinating
(sprouting) and
growing into
plants with
roots, stems
and leaves.

12. Here is a
speeded up
picture of a
bean seed
germinating
and
growing.

13. After the seed
germinates (sprouts)
and grows into an
adult plant, the plant
flowers.
It is the flower that
makes seeds for
new plants to grow
and develop.
This process from seed to adult plant to
flower to seed is called:

18. How a Seed Grows into a New Plant
• The life of a plant begins as a seed.
• Once a seed is watered and warmed, it germinates.
• The root pushes through the seed coat.
• The roots of the seedling grow down into the soil
and the leaves and stem push out of the ground.
• The stem and its leaves grow toward the sunlight.
• The leaves make the plant’s food.
• The flowers form and bloom.
• New seeds are formed inside the flower or within
the fruit that comes after the flower dies
• The seeds are scattered and wait to start growing.

This next one is a exercise on the things that are necessary for a seed
to germinate.

20. Remember…
When the embryo (baby plant) inside
the seed begins to grow, we say the
seed sprouts or germinates.
The young plant that grows from
a seed is the seedling.
The seedling grows into an adult
plant and flowers.
The flowers produce seeds.
