The development of a plant or an organism from a seed or any similar structure. Let's see the stages of seed germination: Step 1: water fills the seed - Imbibition 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 starts respond to the light - termed as photmorphogenesis. Our topic for today is Seed Germination. 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 the embryo. Conditions required for the growth of a seed are Moisture, Warmth, Nutrient rich soil, Sunlight and 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 and the embryo starts getting nourishment. The first sign of growth is a tiny root which comes out of the seed. With more and more nourishment, the embryo starts growing. 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.
