Question

Human gametes differ from all other body cells in being

• A. Haploid
• B. Diploid
• C. Motile
• D. Without cell wall

Answer 1

Answer: (A)

Haploid

Human gametes are haploid while the other cells of the body are diploid. The gametes are produced by the meiotic division of the parent cell in the respective gonads.

The large motile female gamete is the ovum which is produced in the ovary. The ovum is haploid and it is formed by meiosis of primary and secondary oocyte in the ovary. It has half number of the chromosome to that of the parent cell.

The small motile male gametes are known as sperm which is produced in the testis. It is produced by meiosis of primary and secondary spermatocyte. It has half number of the chromosome to that of the parent cell. The two dissimilar gametes fuse to form a diploid zygote by the process of syngamy.

So, the correct answer is option A.
