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 the process 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.

Essentials

• 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 is germination for Class 7th?

Ans. (i) The process by which a new plant grows and develops frohi a seed into a seedling under appropriate conditions is called germination. During germination various parts of seeds are formed that protect the growing embryo like seed coat.

What factors are needed for a seed to germinate?

Seed germination depends on both internal and external conditions. The most important external factors include right temperature, water, oxygen or air and sometimes light or darkness. Various plants require different variables for successful seed germination.

What three conditions needed for seeds to germinate?

Water – seeds need enough moisture to germinate. However,too much water can “drown” them by preventing the intake of oxygen.

How can you tell if a seed has germinated?

When you can see the sprout, you know the seed has germinated. It’s that simple-you know that your seeds have germinated when you can see the sprouts. Shoots from one batch of seeds often develop with different speeds, so don’t worry, if only few sprouts are up yet.

Starting seeds indoors is usually the fastest way to germinate seeds, but black mulch plastic can accelerate the process outdoors. A layer of black plastic spread over the soil and secured with landscaping pins can raise soil temperatures by as much as 10 degrees, hastening squash seed germination by a week or more.
