Question

Strophiole in gram seed is:
A. Seed coat
B. Cotyledons
C. Scar left by funicle out growth.
D. Micropyle

Answer 1

Hint :Before going through the question , let us first know about the very basic thing I.e. seed. A seed is an immature plant with a protective covering around it. Crop formation is a part of the reproduction process in seed plants, known as spermatophytes, which include gymnosperm and angiosperm plants. After pollen fertilisation and some development inside the mother plant, the ripened ovule produces seeds. The embryo is formed from the zygote, and the seed coat is formed from the ovule's integuments

Complete Step By Step Answer:
The gram seeds have a brown colour to them. On one hand, they're pointed, and on the other, they're round. These are found in a tiny fruit known as a pod. There are two or three seeds in each gram pod. A stalk known as the funiculus attaches the seeds to the pod's wall. The funiculus leaves a scar on the seed called the hilum when the mature seed is detached. Simply blow the hilum and the micropyle appears as a tiny pore. During seed germination, water is absorbed via the micropyle. Water oozes out of the micropyle when the soaked seed is squeezed. The tough seed coat protects the seed. The tough seed coat protects the seed. The outer brownish testa and the papery white membranous tegmen make up the seed coat. The seed coat serves as a protective layer. It shields the seed from desiccation, mechanical damage, and temperature extremes. It also protects the seed from bacterial, fungal, and insect attack.

When the seed coat is removed, two large and fleshy cotyledons are visible. The two cotyledons are connected to the embryonal axis laterally. In both sides, the embryonal axis extends beyond the cotyledons. The radicle is the lower pointed end of the axis, and it represents the embryonic or rudimentary root. The other end has a feathery appearance. It's known as the plumule. It is the future plant's first apical bud, which grows into the shoot. Only after separating the two cotyledons can the plumule be seen. The hypocotyl is the portion of the axis between the radicle and the point of connection of the cotyledons to the axis, and the epicotyl is the portion of the axis between the plumule and the cotyledons. The embryo is made up of the axis and the cotyledon.
Funicle outgrowth leaves a strophiole in the gram seed. Strophiole is a tubercle or excrescence found around the hilum of certain seeds. It is an outgrowth in gram seed.
As a result, choice: ( C) Scar left by funicle out growth is the correct answer.

Note :
Seeds are vital for both biological and economic reasons. They are high in protein, starch, and oil reserves, which aid in the early stages of plant growth and development. Many cereals and legumes are significant food sources for a large proportion of the world's population because of these stocks.
