Germination is the process by which a seed begins to grow, where the root and shoot emerge from the seed to form a new plant. Seeds have different parts like the seed coat and hilum. After germination occurs, the radicle root emerges first followed by the splitting of the seed coat and expansion of the cotyledons which provide food for the new seedling. For germination to take place, seeds need proper conditions like water, oxygen, and the right temperature, and some seeds also require specific light levels.

GERMINATION
1. GERMINATION
GERMINATION is when a
ROOT
and a SHOOT
i begin
to grow out from the
SEED .
This is the beginning of a
new plant !!
2. SEEDS
SEEDS have different parts : SEED
COAT (which covers the seed) and
the HILUM (where the seeds was
attached to the mother plant)
After germination, the first root
emerges (RADICLE), the seed
coat softens and splits and the
COTYLEDONS (or seed leaves
which contain food for the new
seedling) begin to expand.
3. CONDITIONS NEEDED FOR
SEED GERMINATION
SEEDS remain dormant or inactive until
CONDITIONS are RIGHT for
GERMINATION.
All SEEDS need
WATER
OXYGEN
and proper TEMPERATURE
in order to GERMINATE.
Some SEEDS require proper LIGHT also.
SOME germinate better in FULL LIGHT
while others require DARKNESS to
germinate.
