Question

Seed develops from?
A. Embryo
B. Ovule
C. Embryo sac
D. Ovary

Answer 1

Hint A seed is an embryonic part of the plant. It is enclosed in a protective outer covering. The seed is formed during the process of reproduction in plants. These include seed plants, the spermatophytes, gymnosperm, and angiosperm plants.

Complete answer:
> Option A- The plant embryo also known as the seed embryo, is the part of a seed or bud. It contains the earliest forms of a plant's roots, stem, and leaves. The embryo develops after fertilization. It is generally contained within a seed or bud.

> Option B- Seeds are the product of the ripened ovule. These are formed after fertilization by pollen and when some growth occurs within the mother plant. The seed coat is formed from the ovule

> Option C- The embryo sac is known as A large cell that develops in the ovule of flowering plants. It is similar to the female gametophyte of lower plants, but it is very much reduced. Usually, it contains eight nuclei formed by the division of the megaspore mother cell.

> Option D- the ovary in plants is a part of the female reproductive organ of the flower or gynoecium. Specifically, it is the part of the pistil. Ovary holds the ovule. It is located above or below or at the point of connection of the petals and sepals at the base.

So the answer is option B, 'ovule'.

Note: Seeds produced by the plants serve several functions for them. These functions are the dispersal to a new location, nourishment of the embryo, and dormancy during unfavorable conditions. But mainly, Seeds are means of reproduction. Most of the seeds are produced from sexual reproduction. They produce a remixing of genetic material and phenotype variability on which natural selection acts.
