What are the 3 stages of germination?
There are three major stages in the germination process. These are the imbibition of water, increased metabolic activity, and swelling of cells. Germination begins with the seed's imbibition (absorption) of water.
What are the 3 steps of germination?
The Seed Germination Process :
- Imbibition: water fills the seed.
- The water activates enzymes that begin the plant's growth.
- The seed grows a root to access water underground.
- The seed grows shoots that grow towards the sun.
- The shoots grow leaves and begin photmorphogenesis.
What are the steps of germination?
The Seed Germination Process
- Step 1: Imbibition: water fills the seed.
- Step 2: The water activates enzymes that begin the plant's growth.
- Step 3: The seed grows a root to access water underground.
- Step 4: The seed grows shoots that grow towards the sun.
- Step 5: The shoots grow leaves and begin photmorphogenesis.
What is the stages of germination?
Once the seed is metabolically activated, germination proceeds according to the following stages: The seed coat (testa) ruptures and the embryonic root (radicle) grows into the ground to extract key nutrients and minerals. The cotyledon emerges and produces the growing shoot's first leaves.
What are the 4 stages of germination?

What are the stages of seed germination?
The process of seed germination includes the following five changes or steps: imbibition, respiration, effect of light on seed germination, mobilization of reserves during seed germination, and role of growth regulators and development of the embryo axis into a seedling.
What are 4 conditions for seed 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.
What are the 5 stages of germination?
The process of seed germination includes the following five changes or steps: imbibition, respiration, effect of light on seed germination, mobilization of reserves during seed germination, and role of growth regulators and development of the embryo axis into a seedling.
What are the 6 stages of germination?
Learn The Six Plant Growth Stages
- Sprout. Each seed contains a small parcel of nutrients that is all they need to germinate and begin growing their first pair of leaves.

What happens in each stage of germination?
During the first phase (Imbibition), the seed intakes water, swells, and extends its first root (radicle) During the second phase (Dormant) the seed digests the nutrition inside of it and sprouts. During the third phase (Growth), the seed continues to grow exponentially into adulthood.
