Germination of Seed Class 5

Define Germination 

The process by which a seed grows into a young plant, or seedling, is called Germination. 

 

  • A seed germinates only when it gets enough light, air, water, and warmth.
  • During the early stages of germination, the seedling uses the food stored inside the seeds for its growth.
  • When the seed receives adequate light, water, air, and warmth, it becomes soft and spongy.
  • The seed coat then breaks and the young plant comes out.
  • The young plant develops roots and shoots.
  • Tiny leaves develop on the shoot and start making food. This young plant is called a seedling.
  • The seedling absorbs water and nutrients from the soil with the help of its roots. As the plant grows in size, it develops more leaves
  • . The seed then shrinks and disappears.
  • The seedling grows to become a new plant.
  • All seeds do not grow into new plants because some are eaten by animals, some get destroyed by rain or wind, while some get insufficient air, water, or warmth.
