AP BIOLOGY

Detailed explanation-1: -This stage is referred to as Imbibition. It starts the growth process by activation of enzymes. The seed activates its internal physiology and starts to respire and produce proteins and metabolizes the stored food.

Detailed explanation-2: -When a dry seed comes into contact with moist soil or growing media, the seed begins to take up water through the seed coat. As it takes up more water, the seed expands and the seed coat cracks open. The embryo inside the seed is made up of a small shoot and a small root. The root is the first to emerge from the seed.

Detailed explanation-3: -germination, the sprouting of a seed, spore, or other reproductive body, usually after a period of dormancy.

Detailed explanation-4: -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.
