Question

What is morula?

Hint:

The morula is an early developmental stage before the blastocyst formation, crucial in mammalian embryogenesis.

Answer 1

The morula is an early stage in the development of an embryo, consisting of a solid ball of cells resulting from the division of the fertilized ovum. Step 1: Formation of morula.
After fertilization, the zygote undergoes cleavage to form a ball of cells. This stage is called the morula, which appears like a mulberry, hence the name.
Step 2: Characteristics of morula.
- It is a solid ball of cells, each called a blastomere. - It usually occurs after 3-4 days post-fertilization in humans.
Final Answer: Morula is an early stage of embryo development, consisting of a solid ball of cells.
