Verified Answer
After fertilisation, the ________ divides repeatedly to give rise to a...
Solution: The fusion of the male and the female gamete, i.e., the sperm and the ovum, is called fertilisation. This results in the formation of a single-celled zygote. After fertilisation, the zygote repeatedly divides to give rise to a ball of cells. This ball of cells eventually develops into the various types of cells and tissues in an organism.

Explanation:
Zygote formation:
- After fertilisation, the sperm and egg fuse to form a zygote.
- The zygote is the first stage of development of a new organism.
Cell division:
- The zygote undergoes a series of cell divisions through a process called cleavage.
- During cleavage, the zygote divides repeatedly to form a ball of cells known as a morula.
Formation of blastocyst:
- The morula continues to divide and eventually forms a hollow structure called a blastocyst.
- The blastocyst is made up of an outer layer of cells called the trophoblast and an inner cell mass.
Implantation:
- The blastocyst then implants itself into the lining of the uterus.
- This process is crucial for the further development of the embryo.
Embryo development:
- The inner cell mass of the blastocyst gives rise to the embryo.
- The embryo undergoes further differentiation and development to form various tissues and organs of the new organism.
Therefore, after fertilisation, the zygote divides repeatedly to give rise to a ball of cells, which eventually develops into an embryo through a series of complex developmental processes.
