How Sunflower Seeds Get Spread?
A seed is simply an underground stem enclosed within an outer protective covering. The actual formation of this seed inside a plant is a complex part of plant reproduction, the sperms, which includes both the x and the y chromosomes. In order for the plant to grow, one or both of these chromosomes must be present in the pistil. The seeds will then germinate and begin to grow. Seeds are released from the plant at a fixed rate and on an individual basis. The faster the seed grows, the bigger it is; whereas, the slower the seed grows, the smaller it is.
Seeds are not necessary for flowering plants to grow. Flowering plants obtain their food through pollination by bees and other insects, which are facilitated by the presence of floral buds. Through flowers, a flower opens up to expose more seeds, which in turn are sown and new plants are created. In such a way, seeds are part of a plant’s reproductive system. So far, we have been discussing the role that seeds play in the creation of a new plant; but seeds are also a component in the distribution of matter from a plant.
Seeds are contained in an ovule, which is a tiny fruit or flower that contains no seed. An ovule is enclosed within an ovary, which is a sac full of fluid. When the female fertilizes an ovule with her own pollen, this process causes the ovule to swell and the seed to be released. The ovule then travels through the uterus and out of the body.
There are many seeds in the plant. In the ovary, the ovule contains one seed. The testa contains many seeds, usually eight in number. These are held together by a thin and flexible cords called the testaceous glands. These cords transfer the seed to the lower parts of the plant, where it is nourished and grows. When the plant is ready to flower, these cords are expelled along with the seed.
Another type of seed dispersed by wind is cereal grains. These seeds are used to make cereals such as corn, wheat, barley, and rice. Many people like to grow them for their consumption and for making flour for baking breads and desserts. Other people like to grow these grains for ornamental purposes, for example, they are sometimes used to make petals on flowers.
A third type of dispersal of seeds is by means of fungi. Fungi reproduce seeds by means of division and multiplication. It is therefore not surprising that mushrooms and other fungi grow seeds. This happens at a rapid rate, so that the gardener may notice that some of his or her plants are growing much sooner than others. Most of these fungi produce a crop of different fruits after repeated divisions.
One kind of fungi produces a crop of new plants every year, and this is by means of a process called transpiration. This process occurs when the roots of a plant to draw water from the atmosphere. As the water evaporates, so does the plant stem and part of its roots. These roots go into the ground, where they secrete water and nourish the new plant that grows from these roots. This is the basic process by which seeds are dispersed by sunflower plants during the growing season.
One type of fungi that is particularly efficient in getting seeds to sprout is the fungus myopia. It coats young plants with a special coating that keeps the seeds protected until they are established. This coating, called a mycohydra coat, is produced by the myopia itself. This mycohydra coat prevents the seed from becoming wet when it passes through the plant’s leaves. This coating also makes it easier for seeds to germinate.
