Question

Gametic meiosis occurs in
A. Higher plants
B. Algae
C. Animals
D. Bacteria

Answer 1

Hint: Gametic meiosis is the process which occurs during gamete formation and results in the formation of haploid gametes.

Complete Answer:
Let us first understand what meiosis is, it is the process by which the single cell divides as produces four cells. In gametic meiosis, the following steps takes place,
It occurs during gamete formation which results in haploid gamete formation
The gametes fuse during fertilization forming a zygote (diploid)

Option A: In higher plants meiosis occurs, but not gametic meiosis. Therefore, this is the incorrect option.

Option B: Algae has sporic meiosis and not gametic meiosis. Therefore, this is the incorrect option.

Option C: In animals, gametic meiosis occurs. This can be understood using the following explanation,
In animals, egg cells and sperm cells are haploid cells but when they fuse they form a single cell known as zygote which is a diploid cell. Therefore, this is the correct option.

Option D: Bacteria reproduces by binary fission which is an asexual mode of reproduction. There is no mitosis or meiosis involved. Therefore, this is the incorrect option.

Thus, the correct option is C) Animals.

Additional information: The difference between gametic meiosis and zygotic meiosis is as follows,

Sl.No	Gametic meiosis	Zygotic meiosis
1.	The meiosis occurs during gamete formation	The meiosis occurs in the zygote
2.	The division leads to formation of haploid gametes	The division leads to formation of haploid individuals
3.	During fertilization, the gametes fuse to form diploid zygote, i.e. they have diplontic life cycle	The division of zygote leads in formation of haploid organisms i.e. having haplontic life cycle
4.	Example includes sexually reproducing organisms	Example includes lower plants

Note: Cell division is the process by which a parent cell divides into two or more daughter cells. Cell division usually occurs as part of a larger cell cycle. There 2 types: 1) Mitosis 2)Meiosis.
