Lesson Two Review
About Seeds
Inside every seed is a dormant baby plant.
Dormant means the baby plant is sleeping.
The baby plant is called an embryo.
When it begins to grow, the new plant is
called a seedling.
What does a seed need to wake up?
Warmth
Water
Air
What is the Testas?
The shell on the outside of a seed is the testa.
The testa protects the embryo like a coat.
The testa comes off when the seed becomes warm
and wet.
The belly button of the
seed, where it was once
attached to the plant, is
called the hilum.
What is Inside a Seed?
Cotyledons provide food the embryo as the
seed begins to grow into a plant.
Endosperm is the food absorbed by the
cotyledons to help the embryo grow.
The radicle is the embryo’s root which
becomes the root for the plant.
The hypocotyl grows and searches for light.
It is the stem for the plant.
The epicotyl is the top of the embryo, from
which the plumule sprouts and becomes
leaves.
What is Germination?
Germination is when water loosens the testa
and the embryo begins to wake up and
grow.
Two different kinds of
angiosperms.
Monocots
One cotyledon in the
seed
Veins run straight up
and down
Flower petals in
multiples of three
Dicots
Two cotyledons in
the seed
Veins branch outwards
from the midrib
Flower petals in
multiples of four or
five
