(Entry 1 of 2) 1a(1) : the grains or ripened ovules of plants used for sowing. (2) : the fertilized ripened ovule of a flowering plant containing an embryo and capable normally of germination to produce a new plant broadly : a propagative plant structure (such as a spore or small dry fruit)
What is seed definition Class 8?
Seed refers to the fertilized, matured ovule that contains an embryonic plant, stored material and a protective coat or coats. A seed is a mature ovule that comprises an embryo or a miniature undeveloped plant and food reserves, all enclosed within a protective seed coat.
What is seeds in science?
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants.
What is the definition of seed agriculture?
Agricultural seed means the seed of any domesticated grass or cereal, and of any legume or other plant which is grown as turf, cover crop, forage crop, fiber crop, or field crop, and mixtures of such seeds. It does not, however, include any variety that is generally known and sold as flower seed or vegetable seed.
What is seed class5?
A seed is a small embryonic (baby) plant enclosed in a covering called seed coat. It is formed as part of reproduction in seed plants. Seeds grow into a new plant after germination.
What are seeds Class 6?
A seed is a basic part of any plant. The ovules after fertilization, develop into seeds. A seed is made up of a seed coat and an embryo. The embryo is made up of a radicle, an embryonal axis and one (wheat, maize) or two cotyledons (gram and pea).
What is a seed and their importance?
Seeds and their importance. Seeds are fertilised, mature ovules—the result of sexual reproduction in plants. Not all plants produce seeds, but those that do often rely on these seeds to replicate themselves over successive seasons and years. Seeds are of immense biological and economic importance.
What is true seed?
True seed means a mature fertilized ovule consisting of an embryo, with or without an external food reserve enclosed by a seed coat.
How is seed formed?
When pollen lands on the flower’s stigma, it germinates and forms a pollen tube, which then quickly grows towards the plant’s ovary. Once it finds an ovule, the pollen tube bursts to release sperm cells, which fertilize the ovule and initiate seed formation.
What is seed by Byjus?

What is a seed for kids?
Seeds are the small parts produced by plants from which new plants grow. In a flowering plant, three parts work together to help a seed develop and grow into a new plant.
What are seeds Class 9?
A seed is a fertilised, matured ovule of a flowering plant, containing an embryo. This tiny embryo enclosed within the seed devolves to form a new plant by the process of germination. Plant embryo in seeds have structures called cotyledons.
What is seed and its type?
There are two overarching categories of seeds: dicotyledonous and monocotyledonous. Seeds are placed into these categories based on how many embryonic leaves they have. Embryonic leaves are the leaves inside the unsprouted seed.
Why are seeds important?
Seeds are of immense biological and economic importance. They contain high protein, starch and oil reserves that help in the early stages of growth and development in a plant. These reserves are what make many cereals and legumes major food sources for a large proportion of the world’s inhabitants.
What are the 3 types of seeds?
Based on the type of food we get from seeds, there are three classifications: Grains, pulses, and oilseeds.
- Grains include rice, wheat, jowar, maize and ragi.
- Pulses include grams, peas and beans.
- Oilseeds include groundnut, sesame, mustard, coconut and sunflower seed.
