How Do Seeds Germinate?
Seeds are the end product of germination. A seed is simply an immature plant enclosed within an outer covering. The development of the seed inside the ovary is part of that process of sexual reproduction in seed plants, which includes both the gymnospermous and the angiosperm plants. Seeds are considered to be living organisms. Seeds are not like other living cells such as bacteria or viruses in that they reproduce themselves by means of the division and the division of asexually reproduced seeds.
Seeds are made up of a single cell - an organism. When the cell divides to form a grain, the cell is considered to be alive because it divides once again to form a new living thing. The sperm is present in the egg white through the female side of reproductive organs called a zygote. After fertilization, the zygote is sealed off from the outside world and kept in the follicle until the spores begin to germinate.
Seeds are the end products of a living thing. When a seedling is formed in nature the developing embryo grows into the desired plant. In nature, seeds are tiny organisms that float in water. The development of seeds involves the division of an organism that has already grown under the right conditions into a new living organism.
An embryo develops in nature by means of external factors. These factors include temperatures, lighting, nutrient sources, and physical stresses. The different external factors that initiate the development of seeds are referred to as the constituents of a seed coat.
External factors initiate the germination of seeds. When the embryo grows into a flower or a fruit of the process of division of cells occurs. At this point the external environment and the chemical composition of both the embryo and the plant to determine if the embryo will grow into a living plant or a dead one. The growth and development of the seeds require many components such as the nutrients Thiamin, N-acetyl-d Glucosamine, F-stearoyl-group, Zinc, and other nutrients. The nutrients serve as building blocks for the plant to grow and reproduce.
External environmental factors also influence the germination of seeds. A cold winter season can delay the germination of seeds. The temperature of an egg white makes a difference when it comes to making the difference between the growth and development of seeds. The temperature that is optimal for the growth of seeds in an oyster or chicken egg has been determined and is referred to as the critical temperature. This temperature ranges between seventy-five to eighty degrees Fahrenheit.
Plants that grow better when grown in areas with cooler temperatures have been developed and tested over years. New plants that produce more seeds when grown in warmer climates have been studied and have proven that they work best when grown in hot areas. Plant scientists understand that plant life begins with a seedling which becomes the embryo and then produces the plant's mature flower, leaves, and roots. The process is then repeated over again in nature. If the temperature inside of a plant is higher than seventy degrees Fahrenheit during the development of its seeds, the plant will not germinate.
The reasons why seeds do not germinate have to do with the temperature, external environment, and the quality of the egg. The temperature has been shown to influence the development of the seed coat which can be altered by planting the seeds too close together or not planting them at all. External environment plays a role in whether or not a seed will germinate. Sealing containers, using plastic garden pots instead of glass or making sure that the young plant has been placed within a shady area has helped many seeds germinate.
