Morula formed at the end of clearvage is …………… celled

Options

A. 14
B. 16
C. 18
D. 20

Answer

To solve the question regarding the number of cells in a morula formed at the end of cleavage, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Cleavage**: Cleavage is the process that occurs after fertilization, where the zygote undergoes a series of mitotic divisions. This process results in the formation of smaller cells called blastomeres.

2. **Identify the Stages of Cleavage**: The first cleavage division results in two cells (2-cell stage), the second cleavage results in four cells (4-cell stage), and the third cleavage results in eight cells (8-cell stage). This process continues with further divisions.

3. **Determine the Morula Stage**: The morula is a solid ball of cells that forms after several rounds of cleavage. Specifically, the morula stage is typically recognized as the 16-cell stage.

4. **Select the Correct Option**: Given the options provided (A: 14, B: 16, C: 18, D: 20), the correct answer is B: 16.

### Final Answer:
The morula formed at the end of cleavage is **16-celled**.
