Question

Which of the following is an example of a dicotyledon seed?
(a)Maize
(b)Mustard
(c)Banana
(d)Garlic

Answer 1

Hint: Dicotyledons are often classified as dicots. The term dicotyledons refers to the two embryonic cotyledons in the seed. A plant native to the Mediterranean region and linked to nutrient-rich vegetables such as broccoli, cabbage, and brussels sprouts is an example of dicotyledon seed. Both its seeds and leaves are edible, making your dishes a versatile addition.

Complete answer:
There are two groups of flowering plants (angiosperms), namely monocots and dicots.
Monocots- Monocots are called plants which have only one cotyledon in the seeds. For instance, maize, banana, garlic, etc.
Dicots- In their seeds, plants that produce two cotyledons are called dicots. A few examples of dicots include mustard, beans, legumes, and apples.
One of the two classes from which all the flowering plants or angiosperms were formerly split is the dicotyledons, also known as dicots. The name refers to one of the group's typical features, namely that two embryonic leaves or cotyledons are present in the seed. There are about 200,000 species within this group.

Additional Information: A Dicotyledonous Seed Structure:
The embryo consists of an embryo axis and two cotyledons in the dicotyledons. Cotyledons normally have a swollen appearance since the growing seedling serves as a food reserve. There are two ends to the embryo axis. The one forming the shoot tip is called the plumule, and the radicle is called the part at the lower end forming the root tip. The entire material is contained inside a protective cover called the seed coat. An outer layer called testa and an inner layer called tegmen constitutes the seed coat. Moreover, through a structure called the hilum, the seed is attached to the fruit.
So, the correct answer is, ‘Mustard’.

Note: In plants, seeds are an important part of sexual reproduction. It is produced in plants as the final result of sexual reproduction, and is unique to angiosperms and gymnosperms only. Gymnosperms have no fruit or flowers, so their seeds are "naked" or exposed. Angiosperms, on the other hand, have matured ovules that form after fertilization inside the fruits. It consists of an embryo called the seed coat that is wrapped in a protective outer coating. It has been reported that certain seeds have triploid endosperm. There are three parts of an embryo such as a radicle, an embryo axis, and cotyledons. Seeds have been categorized into two such as monocotyledonous and dicotyledonous seeds based on the number of cotyledons.
