How Seeds Are Stored Food?
Seeds are the reproductive part of plants. A seed is actually an embryonic plant enclosed inside a protective outer shell. The development of the seed inside the shell is also part of the process of vegetative reproduction in plants, which includes the sperms and the gymnosperm plants. The seeds that grow end up as food for the animals and eventually get expelled as the byproduct of pollination on the plants.
Seeds are the food source of certain animals like ants and bees. They contain proteins, carbohydrates, fats and lipids that are needed to nourish the new plants that will grow up. The process of making seeds and their developing inside an embryo is very complex. It is during the actual germination of seeds from the ovary that the complete lifecycle of a seed begins. This is why a new plant that is being grown is not complete without seeds.
There are different kinds of seeds for different plant life. The coat that a seed coat provides protects it against harsh weather conditions that may damage or even kill the seedling. This coat also helps the seeds sprout more quickly than without the coat and allows the seeds to be dispersed more broadly so that they have access to as many nutrients as possible before they die off. A plant needs to shed its outer coat to make way for a new seedling so that it can grow properly.
The actual germination of a seed involves two things. One is through the manual process of lifting the zygote out of the ovary. The second is through a chemical method called transpiration. Transpiration uses the suction of water through the seed coat to actively push the seeds out of the embryo. After the seeds are actively expelled, they are covered with a thin film of mineral substance called the nimbus that ensures the seeds do not float away.
Seeds are categorized according to whether they fall into one of three categories - ferns, gymnosperms, or seedling. Ferns are small plants with dense, hard leaves. The gymnosperm plant is the largest of all seed plants and is classified according to its tubular shape and short, stubby leaves. Most seed plants are ferns, but not all ferns can grow to become gymnosperm or seedlings.
Seedlings are plants that have already produced a set of reproductive cells, or seeds. These seeds are encased in an egg case that is capable of storing a few cells until the plant reproduction comes about. The actual process of germination happens at this point. The cells that are responsible for producing the plant's reproductive tissues -called zeaxanthin - are released from the egg case and begin reproducing. This starts a chain reaction that will help the plant to reproduce more seeds.
When you look at seed plants under the microscope, there are two types of cells you see. There are somatic cells which are responsible for creating the plant's future reproductive tissues. Somatic cells can be found both in the developing plant as well as in an adult plant. When the embryo is developing in the lab, a technician will use a microscope to examine the somatic cells. A piece of tissue will be inserted into a petri dish containing a culture medium. Over time, the cells in the petri dish will replicate and grow into the embryo that is contained in the middle of the petri dish.
An ovule is the immature form of a seed. It is a very small structure that resembles a bean with a hard cover. This hard cover, called a seed coat, is what will give the plant its seed capsule. The seed coat is important for seeds because it helps prevent the seeds from drying out while they are stored food. The ovule will continue to grow until the plant is ready to sprout seeds.
