Every living thing begins, can reproduce, and dies. In many plants, this life cycle begins with a seed.
Packet of Life
Have you ever planted seeds?5
A seed holds the beginnings of a plant’s first roots, stem, and leaves.
6
A tiny plant waits inside each seed.
A seed ready to grow.
Roots grow bigger.
Roots begin to grow.
7
Now a stem begins to grow.
Stem
Leaves
8
Some plants begin from a bulb. Bulbs grow roots, stems, and leaves, too.
9
An onion plant begins
from a bulb.
10
The tiny plant grows. Roots make a strong base. They take in water and nutrients from the soil.
Life Unfolding
11
Roots grow.
The first shoot becomes a strong stem. The stem carries water and nutrients to the plant and holds up the leaves.
12
Leaves grow from
plant stems.
13
Stem
Leaves use sunlight, air, and water to make food for the plant.
14
Leaves are food factories for plants.
15
Leaves
Flowers
16 Marigold seeds
Some plants make flowers. Plants make seeds inside their flowers.
17Marigold flowers make
marigold seeds.
18
When they are ready, some seeds fall to the ground. Animals or the wind will carry other seeds to new places to grow.
19
The wind blows
dandelion seeds to a
new place.
At the end of the life cycle, plants die. Their bodies decay. New plants will grow in their place.

1. The acorn sprouts.
4. The tree makes flowers and acorns. After many years, the tree dies.
213. The tree grows bigger.
2. A young tree grows.
1. How does each plant part help the plant grow?
2. What role do flowers play in a plant’s life cycle?
3. Can you think of some plants that grow from bulbs?
