Detailed explanation-1: -During the beginning stage of germination, the seeds take up water rapidly and this results in swelling and softening of the seed coat at an optimum temperature. This stage is referred to as Imbibition. It starts the growth process by activation of enzymes.
Detailed explanation-2: -Light, water, oxygen, and temperature are essential conditions for seed germination.
Detailed explanation-3: -Seed germination starts with imbibition, when the seed takes in water from the soil. This triggers root growth to allow the seed to get more water. Then, the shoots develop and grow towards the sun above ground. After the shoots reach the ground, leaves form, allowing the plant to harvest energy from the sun.
Detailed explanation-4: -The process by which a seed produces a baby plant or seedling is called germination.
Detailed explanation-5: -Germination is the process of seeds developing into new plants. First, environmental conditions must trigger the seed to grow. Usually, this is determined by how deep the seed is planted, water availability, and temperature.
