What three things are needed for germination?
- The beginning of the growth of a seed into a seedling is known as germination.
- All seeds need water, oxygen and the right temperature to germinate.
- Dormancy is a state of suspended animation in which seeds delay germination until conditions are right for survival and growth.
What are the 5 stages of germination?
Such five changes or steps occurring during seed germination are:
(1) Imbibition (2) Respiration (3) Effect of Light on Seed Germination(4) Mobilization of Reserves during Seed Germination and Role of Growth Regulators
and (5) Development of Embryo Axis into Seedling.
How does germination start?
Germination begins
with imbibition
, a big word for taking in water. This is the major trigger to start the period of waking up from dormancy. As the seed takes in water, it gets bigger and produces enzymes. … The seed grows, and the radicle, or first stage of the root, emerges from the seed.
What are the 6 stages of germination?
For humans, the progression is infant, toddler, adolescent, young adult, middle aged adult, and senior citizen, while plants go from seed to sprout, then through
vegetative, budding, flowering and ripening stages

When conditions are right the
seed starts to take in water
. As water is taken in, the seed swells bigger and bigger until the coat splits apart. Air can then get to the seed.

What is germination explain with diagram?
1) Imbibition: water fills the seed. 2) The water activates enzymes that begin the plant's growth. 3)
The seed grows a root to access water underground
. 4) The seed grows shoots that grow towards the sun. 5) The shoots grow leaves and begin photmorphogenesis.
What are 2 types of germination?
- Epigeal Germination: In this type of germination, the hypocotyl elongates rapidly and arches upwards pulling the cotyledons which move above the soil. …
- Hypogeal Germination: In this type of germination, the epicotyl elongates and the cotyledons remain below the soil.
Why is germination important?
Seed germination starts with imbibition, when the seed takes in water from the soil. This triggers root growth to allow the seed to get more water. … Seed germination is
important for natural plant growth and growing crops for human use
.
What is not needed for germination?
Complete step by step answer: Development of plants from a single seed is called seed germination. Factors such as oxygen, water and temperature are required for seed germination, but
the light
is not an essential factor amongst other factors.
