Germination of seeds

'

In the daytime the seed makes no effort to germinate or grow. But as soon as night falls, the seed begins to grow, sprouting as soon as dawn appears. That is because it has dormant powers, particles born with the seed which store the seed’s vital essence. It has them but is not capable of using them because a mutation to the germination process takes place during the night that transforms the seed’s dormant powers into life powers.Plants reproduce using eggs and sperm, just like people. However, they don't have physical sex! Male plants release pollen, which fertilize ovaries. The fertilized ovaries develop into seeds, which can then be distributed to make new plants. As the fertilized ovaries develop, a surplus of carbohydrates and proteins are stored inside the seed. This will serve as food for the plant until it can develop leaves. Next, the fertilized plant ovaries develop the hardened coat we see as the outside of seeds to protect them against harsh environmental conditions. The seeds then can be carried away by wind or animals to create new plants.

SEED

Plants reproduce using eggs and sperm, just like people. However, they don't have physical sex! Male plants release pollen, which fertilize ovaries. The fertilized ovaries develop into seeds, which can then be distributed to make new plants. As the fertilized ovaries develop, a surplus of carbohydrates and proteins are stored inside the seed. This will serve as food for the plant until it can develop leaves. Next, the fertilized plant ovaries develop the hardened coat we see as the outside of seeds to protect them against harsh environmental conditions. The seeds then can be carried away by wind or animals to create new plants. After the seed has made it to a new location and is covered with dirt, it can begin germination. 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. When water is plentiful, the seed fills with water in a process called imbibition. The water activates special proteins, called enzymes, that begin the process of seed growth. First the seed grows a root to access water underground. Next, the shoots, or growth above ground, begin to appear. The seed sends a shoot towards the surface, where it will grow leaves to harvest energy from the sun. The leaves continue to grow towards the light source in a process called photomorphogenesis.

Several factors influence if, and how, seeds germinate. The most important factors are water availability, temperature and sunlight. Water is crucial to seed germination. The seed must go through imbibition to activate root growth. However, too much water can be a bad thing, as most gardeners know. When a plant is still growing underground, during root formation, it cannot use the sun to make food like most grown plants do. It must rely on the stored food inside the seed, and oxygen from the environment to make energy. If the soil is too soggy, there will not be enough oxygen and the plant will not thrive. Think about a person being kept underwater. We wouldn't last too long! Seeds are formed and germinate as a natural process of plants in the wild. However, humans also can take advantage of this process to produce food, such as our tasty fruits, vegetables, and other needed products, like cotton or fresh flowers. Humans can grow crops outside, as in traditional farming, or crops can be started inside from seeds in a greenhouse. Seeds are planted in small containers of soil and given the right conditions based on the type of seed. Check out this indoor grow system. Plants are germinated in small cups of soil and water is provided through a plumbing system. The lights overhead ensure that the seeds' shoots grow directly upward. (Source: study.com)
