What is germination in simple words?
Germination occurs when a spore or seed starts to grow. It is a term used in botany. When a spore or seed germinates, it produces a shoot or seedling, or (in the case of fungi) a hypha. The biology of spores is different from seeds.
What is the science definition of germinate?
germination, the sprouting of a seed, spore, or other reproductive body, usually after a period of dormancy. The absorption of water, the passage of time, chilling, warming, oxygen availability, and light exposure may all operate in initiating the process.
What is germinate and example?
The definition of germinate is to start to grow, develop or sprout. When a plant first begins to sprout buds, this is an example of a time when it germinates. When an idea comes up and then starts to be developed and grow, this is an example of a time when the idea germinates.

What are the main stages 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.
