Question

The fusion of male and female gametes results in the formation of
A. Zygote
B. Embryo
C. Sperm
D. Egg

Answer 1

Hint: Syngamy is the process by which organisms increase their genetic diversity. The renovation of genetic material is its primary purpose. The genotype of the newly created cell will differ from that of the gametes. Meiosis balances off the increasing amount of DNA caused by continuous syngamy.
The process of fusing of the male and female gametes is known as syngamy. It takes place in the fallopian tube and leads to the formation of fertilised egg cells or zygotes. To produce a new human, this zygote proceeds through cell division. Fertilization is another name for it.

Complete answer:
Option A: The zygote is formed when a male gamete, sperm, and a female gamete, egg, fuse. The zygote matures into an embryo.
So, option A is correct.
Option B: At the micropylar end of the embryo sac, the zygote develops into an embryo. It is generated when a male gamete unites with an egg cell during syngamy.
So, option B is not correct.
Option C: In anisogamous forms of sexual reproduction, sperm is the male reproductive cell, or gamete. Animals generate spermatozoa, which are motile sperm with a flagellum tail, but red algae and fungi produce spermatia, which are non-motile sperm cells.
So, option C is not correct.
Option D: In most anisogamous species (sexually reproducing organisms), the egg cell, or ovum, is the female reproductive cell, or gamete. This term is used when the female gamete is unable to move (non-motile).
So, option D is not correct.

So, option A is the correct answer.

Note:
Types of syngamy-
Isogamy develops when two gametes that are genetically identical unite. An advanced system of recognition is utilised to distinguish different types of genotypes in order to avoid self-pollination.
Heterogamy is when the gametes are of various sizes. Female gametes are larger, while male gametes are smaller.
When the gametes' mobility differs, it's called oogamy. The non-motile female is the oocyte, while the flagellate male is the spermatozoon.
