Question

Solid ball of cell produced by repeated cleavage is called

• A. Gastrula
• B. Blastula
• C. Morula
• D. None of the above

Answer 1

The correct option is C Morula

The fertilized ovum gets converted to zygote after fertilization. The zygote undergoes repeated mitotic divisions which are known as cleavage. Cleavage takes place along definite planes to form a solid mass of cells. This solid ball-like structure is known as morula. The morula gets transformed to blastula in which the cells arrange themselves in a corner and the cavity formed is called blastocoel.

So, the correct answer is option C.
