What are the 5 steps 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.
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.
Why seed germination is 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. Then, the shoots develop and grow towards the sun above ground. … Seed germination is important for
natural plant growth and growing crops
for human use.

cotyledon, seed leaf within the embryo of a seed. Cotyledons
help supply the nutrition a plant embryo needs to germinate
and become established as a photosynthetic organism and may themselves be a source of nutritional reserves or may aid the embryo in metabolizing nutrition stored elsewhere in the seed.
What softens the seed coat?
Keep plants in warm moist soil or unsterilized sand for several months
to soften seed coats through microbial activity. Seeds may also be planted directly in the summer or fall while soil temperatures are warm. … It may be accomplished by running water over seeds in a container (mason jar) for 12 to 48 hours.
What are the six steps in germination?
