  • Our topic for today is Seed Germination.

  • It's time to work.

  • I know.

  • I will get the seed.

  • The life of a plant begins from a tiny seed.

  • The seed is protected by an outer covering called a seed coat.

  • The seed contains a small baby plant called an embryo.

  • Let's sow the seed.

  • Wait, I have some conditions.

  • Conditions required for the growth of a seed are:

  • Moisture.

  • Warmth.

  • Nutrient rich soil.

  • Sunlight.

  • Good quality seed.

  • Once these conditions are satisfied, the seed begins to grow.

  • The seed absorbs water from the soil and provides moisture to the embryo.

  • The plant cells inside the seed start duplicating.

  • Enzymes get activated.

  • Embryo starts getting nourishment.

  • The first sign of growth is a tiny root which comes out of the seed.

  • Hey, I am Mr. Root.

  • Let us study the process of germination.

  • With more and more nourishment, the embryo starts growing.

  • Sunlight.

  • It's time for photosynthesis.

  • Eventually, the growing plant bursts open through the seed coat in search of sunlight to start its own process of photosynthesis.

  • Once the seed coat falls off, the root starts growing downwards to anchor the seed and to search for more food and nutrients from the soil.

  • Meanwhile, the shoot also starts growing upwards towards the light.

  • Soon, we see a baby plant with tiny leaves.

  • This process of the growth of a seed into a plant is called germination.

Our topic for today is Seed Germination.
