Question

Monocot seeds have
A.Embryo with a single cotyledon.
B.Plumule also called shoot tip is present on the upper side and is protected by leaf-like covering called coleoptile.
C.Radicle is found on the lower side of the embryo.
D.All of the above.

Answer 1

Hint: Monocot plants also called monocotyledons are grass or grass like plants. It includes Corn, wheat and rice, ginger, banana, sorghum, onion, coconut and garlic.

Complete answer:
The monocot seed is made up of following parts:
1.Seed coat: It is the outermost layer of the seed which is usually brownish in colour
2.Endosperm: The major part of the seed is the endosperm which helps in storage of food.
3.Embryo
Let us analyze the options to find out the correct option.

Option A, B & C: The embryo of the monocot seed contains a single lateral cotyledon which is called scutellum.The scutellum is generally shield-shaped and is located laterally towards a side of the embryo axis. At its two ends the embryo axis with plumule and radicle are present. The plumule is protected by coleoptile which is a protective sheath while the radicle is surrounded by coleorhiza. Root cap protects the tip of the radicle

Option D: Since all of the above options are correct.

Hence, the correct answer is option (D)

Note: When the seeds germinate on the cotyledon become the first leaves of the seedling that is why monocots have only one cotyledon.Coleorhiza and coleoptile are absent in dicot seeds.
