true

Answer 2

Answer:

An Embryo is made up of a single cell. The statement is False.

Explanation:

1. During copulation, the male and female gametes fuse together.A diploid zygote is formed when the male gamete (sperm) and female gamete (ovum) join together.
2. Millions of sperm cells enter the female's uterus during copulation.All sperm migrate in the direction of the egg (ovum). Only one sperm out of a million unites with the ovum.
3. The zygote, which is a single-celled organism, is created when sperm and ovum combine.The embryo, which is the earliest stage of embryonic development, is formed from these single cells that have differentiated further.
4. As a result, a single cell creates a zygote, which eventually differentiates into an embryo. Reproductive organs are responsible for reproduction.Primary reproductive organs and auxiliary reproductive organs are the two categories.
5. The term "primary organs" refers to organs that are directly involved in the reproduction process, such as the gonads (the sperm and egg cell).
6. Accessory organs, on the other hand, are those that assist in reproduction indirectly.
7. The zygote divides into a sixteen-celled zygote after it is produced.
8. It then proceeds towards the uterus, where it becomes a blastocyst, a little hollow ball of many cells.
9. The blastocyst forms a pit in the uterine wall and is eventually adhered to the uterine wall.
