A main function of a plant's seed is to?
Solution
A seed is an embryonic plant with a protective coating around it. Seed development is a phase of the reproduction process in seed plants, known as spermatophytes, which include gymnosperm and angiosperm plants. After pollen fertilisation and some growth within the mother plant, the mature ovule produces seeds. The zygote produces the embryo, while the integuments of the ovule produce the seed coat.
Complete answer:
Seeds are, at their core, methods of reproduction, and the vast majority of seeds are the result of sexual reproduction.
Seeds serve a variety of purposes for the plants that make them. The embryo's feeding, dispersal to a new place, and hibernation in unfavourable conditions are all important tasks.
The embryo or young plant is also protected and nourished by seeds.
The most basic function of a seed is to ensure the survival of a species. All of the functional systems work together to keep the plant embryo alive inside the seed until the conditions are right for the seed to germinate and the seedling to survive. Seed germination is influenced by a number of elements, including the amount of sunlight, moisture, and temperature. When seeds fail to develop seedlings that blossom and generate seeds, a species becomes extinct.
Plants that grow in harsh environments can take years, if not decades, to reach suitable germination conditions for a specific species. Seeds are like programmed time capsules in these situations, laying dormant in the earth, waiting for the right conditions to blossom. Seed longevity is demonstrated by annual desert wildflowers.
Seeds supply enough sustenance for the embryos they contain to survive germination. Carbohydrates, lipids, and proteins can all be found in endosperm. Small, quick-sprouting, fast-growing seeds typically have little endosperm.
A substantial supply of endosperm permits seeds and seedlings to survive under difficult circumstances for long periods of time. Coconuts survive thousands of miles of floating to reach coastal shores, where they might take months to germinate. To get it through this phase, the seed provides plenty of endocarp in the form of coconut meat and milk.
Note:
The seed coat serves to protect the embryo while also transmitting information about the external environment. While an impenetrable seed coat may help to keep the embryo safe, it also prevents the embryo from sensing environmental stimuli. The seed coat is made up of the ovule's two integuments, or exterior layers of cells.
