Question

The shoot of a baby plant is called?
a. Plumule
b. Radicle
c. Seed coat
d. Endocarp

Answer 1

Hint: A seed germinate when a plant grows upward and leaves will develop. In the spring season, new shoots in the plant grow, new stems or flowers on woody plants.

Complete answer:
> Plumule: - when a plant is developed, it emerges from the seedling. Plumule is another word for young shoot and it is said to be negatively geotropic as it moves away from soil, its extension rises from hypocotyls, when hypocotyls grows, the cotyledons are grown out of the soil, but, when epicotyls grows, the cotyledons still remains in the soil.

> Radicle: - It is the first part of seedling, the process of germination emerges from the seed. Embryonic root of the plant is Radicle and it grows downward in the soil. Cotyledon is supported by embryonic stem or hypocotyls, above radical. Ridicules are grown out of seed from micropyles.

> Seed coat: - It is one of the three parts of seed, endosperm is the food storage area of the seed, and the plant embryo. A seed coat helps to protect seeds from the extreme weather like heat, freezing and sometimes water which also help it to mature into a plant. It also helps to prevent excess water entrance in seed structure. It also stops the structure from dying.

> Endocarp: - It is the innermost layer and the seed is directly surrounded by it. It can be very hard and non-edible for some fruits like peach, cheery, plum, but it can be edible for some fruits.

Hence, The correct answer is option (A).

Note: Plumule is formed in embryo at the time of germination. It helps in forming a baby plant that develops into an adult plant. It also includes stem apex and the plant's first leaves. In short you can say it gives rise to shooting.
