Question

Select the mismatched pair :-

• A. Microsporangium – Pollen sac
• B. Pollen grain – Male gamete
• C. Embryo sac – Female gametophyte
• D. Megasporangium - Nucellus

Answer 1

The correct option is B Pollen grain – Male gamete

In angiosperms, microsporangium is equivalent to pollen sac, megasporangium is equivalent to nucellus and embryo sac is equivalent to female gametophyte. Pollen grain or microspore represents immature male gametophyte.

The highly reduced male gametophyte of angiosperm plants is a two or three celled pollen grain, whose function is the production of two male gametes and their transport to the female gametophyte, the embryo sac, where double fertilization takes place.

So, the correct answer is "option C"
