FutureStarrGermination of Seed
The water drains out and the seed threatens to die, or perhaps it already has. The seed there hesitates among murky depths, held precariously in limbo between two worlds. Liberty, the sky, and gardening supplies are an ambiguous mix, while nature itself must also be negotiated if one is to bring the seed to fruition. As with so much else, the seed must see to it that it finds its way through this murky, perilous passage of the uncanny.I don't know about you, but I love fruit! Sweet, delicious fruit, though, is actually ripened plant ovaries, or female reproductive organs. The seeds inside the fruits are designed to spread throughout the environment and grow into new plants in a process called seed germination. So if you're a fan of ripened plant ovaries, too, check out this lesson to learn how they grow from tasty snacks into full grown 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.
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.In summary, seed germination is the process of a fertilized plant ovary, or seed, developing into a mature plant. 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. Several factors influence this process, such as water availability, temperature and sunlight. Seed germination is important for natural plant growth and growing crops for human use.
