Seed Germination
Seed Germination – Types:
Seed germination is the process of a seed turning into a plant. It occurs when the seed coat splits and the embryo is released. The embryo then begins to grow and develop into a plant. The process of germination is controlled by the environment and by the embryo itself.
The environment controls the germination of a seed by providing the necessary water and nutrients. The embryo also controls the germination of a seed. It releases enzymes that break down the seed coat and the food reserves in the seed. This allows the embryo to begin to grow.
The germination of a seed is a complex process. It involves the activation of the embryo, the growth of the embryo, and the development of the root and the shoot. The process of germination can take several days or weeks, depending on the species of plant.
Seed germination is an important process for the survival of plants. It allows plants to grow and produce new plants. Seed germination is also important for the reproduction of plants.
Seed Germination – Types, Process & Diagram
- One of the most important steps in the life cycle of a plant is seed germination. This is the process by which a seed starts to grow into a plant. The process of seed germination can be broken down into three steps: water uptake, activation of the embryo, and the growth of the embryo.
- The first step in the process of seed germination is water uptake. The seed must absorb water in order to start to grow. The water enters the seed through the hilum, which is the point where the seed was attached to the plant. The water travels through the seed coat and the endosperm to the embryo.
- The second step in the process of seed germination is the activation of the embryo. The water that was absorbed by the seed causes the embryo to start to grow. The embryo is made up of the cotyledons and the radicle. The cotyledons are the leaves of the plant that will grow out of the seed. The radicle is the part of the embryo that will become the root of the plant.
- The third step in the process of seed germination is the growth of the embryo. The embryo starts to grow and become a plant. The cotyledons grow out of the seed and the radicle grows down into the soil. The embryo starts to produce its own food and grows larger.
