Life Cycle of a Plant
How living things grow, live, and die
2nd grade Science
A plant’s life cycle starts with
a seed.
•Inside the seed is a tiny new plant.
•The outside of the seed has a special covering
called a seed coat.
•When the seed gets the right amount of water, warmth, and air, it
can begin to grow.
•If conditions remain just right, after a time the little seed will
sprout.
•The sprout will grow to look like the plant it came from
As the sprout
continues to develop,
it will grow roots, a
stem, leaves, and
flowers which 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.
When this happens, it is called a sprout.
The Cycle Continues
•Later, leaves begin to form on the plant
stem.
•Now it is called a seedling and can make
its own food.
•Finally, the seedling develops into a plant
which will look like the plant it came from.

What Am I ?
Using the vocabulary worksheet, help your
partner learn the names of plant parts by
giving clues. For example, “I take in water
and minerals from the soil. What am I ?”
Give your partner one clue for each
vocabulary word. Once you have
completed the list with your partner,
switch.
