Transcript Life Cycle of a Plant

Plants
& Trees
Revised by Miss Pflaumer
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.
•The seed leaf has a bit of food or
energy to help the seed to germinate.
When the seed gets the right amount of
water, sun, and air, it can begin to
grow.
When it starts to grow, it is
“germinating”.
•If conditions remain just right, after a
time, the little seed will sprout.
•The little sprout is called a “seedling”.
•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.

Written Assessment
Finally, you will write a paragraph or
paragraphs telling me as much as you
know about plants. You are allowed to
use any of the pages in your “Plant
Folder” to help you. Make sure you
include the parts of trees and plants as
well as their life cycles.
