Question

Which part of the seed is used to protect the seed?
A. Seed coat
B. Embryo
C. Cotyledons
D. None of the above

Answer 1

Seeds are generated by numerous related plant species, and the angiosperms ("enclosed seeds") differ from the gymnosperms ("open seeds") ("naked seeds"). Angiosperm seeds are formed in a hard or fleshy structure known as a fruit, which protects the seeds and ensures proper development.

Complete answer:
A blooming plant's seed is an essential component. They produce a new plant as a result of their actions. They can come in a variety of forms, colors, and sizes. They come in a variety of shapes and sizes, including spherical, wrinkled, winged, and hairy. They will remain dormant until they acquire enough sunshine, water, and soil. Germination is the process of a plant growing from a seed. A seed is made up of three parts:
Endosperm: The endosperm is where the nutrients are kept. It gives the seed nutrition in the form of starch, carbs, and proteins to help the embryo germinate. It can be found beneath the seed coat. Until germination, the seeds can be kept alive by consuming nutrients.
Embryo: A seed's embryo is the most vital component. It is diploid, having been created from a fertilized egg. The embryo contains all of the cells necessary for it to grow into a mature embryo.
Seed Coat: The interior components of seed are protected by a seed coat. The seed coat is made up of two layers. The thick outer layer is known as the testa. Tegmen is the name for the thin inner layer.
Hence, Seed coat, endosperm, and embryo are the three components of a plant seed. The seed coat protects the seed from harm caused by physical, mechanical, temperature, and water. A cotyledon is an embryonic leaf found within a plant's seed. The embryo is made up of precursor tissues for various plant components.

As a result, The seed coat protects the seed so, option A is the right option.

Note:
The term "seed" has a broader definition that predates the above: anything that may be sowed, such as "seed" potatoes, "seeds" of maize, or "seeds" of sunflowers. The seed encased in a shell or husk is sowed in the case of sunflower and corn "seeds", but the potato is a tuber.
