Question

Give the examples of monocot and dicot.

Answer 1

Hint:The cotyledon is the part of the embryo of a seed from which the first leaves of a plant emerges. Seeds can have a single cotyledon or two cotyledons.

Complete answer:
The seed is the end result of sexual reproduction in angiosperms. It is also defined as a fertilised ovule. The seeds are produced within the fruit. Seeds usually consist of a seed coat, cotyledon and embryo axis. The cotyledons are simple structures, usually dense and enlarged due to the storage of food supplies (as in legumes).

The seed is an embryonic plant and is covered in a protective outer covering. Seed formation is part of the reproductive process in seedlings, including gymnosperm and angiosperm. Normally, the seed comprises two essential parts, the embryo and the seed coat. Monocots are the plants whose embryo has a single cotyledon. Examples of monocots include wheat, rice, maize, etc. In dicots, the embryo is made up of two cotyledons. Examples include peas, tomatoes, mango, etc. In most monocotyledons and dicotyledons, the endosperm supplies nutrients to the embryo. The seed coat protects the baby plant from damage or drying out. Matured seeds can be non-albuminous or exalbuminous. Non-albuminous seeds have no remaining endosperm so they are fully absorbed during embryonic growth. Albuminous seeds retain a portion of the endosperm when it is not entirely used during embryo formation.

Note: Cotyledons are not regarded to be true leaves and are often referred to as "seed leaves" since they are merely part of the seed or embryo of the plant. Seed leaves are used to obtain stored nutrients in the seed, nourishing it until the true leaves mature and start to photosynthesize.
