Mitosis and cytoplasmic division function in :

Options

A. gamete formation in prokaryotes
B. growth, tissue repair, and sometimes asexual reproduction in many multicellular eukaryotes
C. asexual reproduction of single-celled eukaryotes
D. both (a) and (b)

Answer

To solve the question "Mitosis and cytoplasmic division function in:", we need to analyze the options provided and understand the functions of mitosis and cytokinesis. Here’s a step-by-step solution:

### Step 1: Understand Mitosis and Cytoplasmic Division
Mitosis is the process of nuclear division where a single cell divides to produce two identical daughter cells. Cytoplasmic division, or cytokinesis, follows mitosis and is the process where the cytoplasm of a parental cell is divided into two daughter cells.

### Step 2: Analyze the Options
We have four options to consider:
- **a. Gamete formation in prokaryotes**
- **b. Growth, tissue repair, and sometimes asexual reproduction**
- **c. Asexual reproduction of single-celled eukaryotes**
- **d. Both a option and b option**

### Step 3: Evaluate Option A
- **Gamete formation in prokaryotes**: This is incorrect because prokaryotes do not undergo mitosis; instead, they reproduce asexually through binary fission, and gamete formation occurs via meiosis in eukaryotes.

### Step 4: Evaluate Option B
- **Growth, tissue repair, and sometimes asexual reproduction**: This option is correct. Mitosis is primarily involved in growth and repair of tissues in multicellular organisms. It can also be involved in asexual reproduction in some organisms.

### Step 5: Evaluate Option C
- **Asexual reproduction of single-celled eukaryotes**: While mitosis does play a role in asexual reproduction of single-celled eukaryotes, this option does not encompass the broader functions of mitosis, such as growth and tissue repair.

### Step 6: Evaluate Option D
- **Both a option and b option**: Since option A is incorrect, this option is also incorrect.

### Conclusion
The most appropriate answer is **b. Growth, tissue repair, and sometimes asexual reproduction**. This option accurately reflects the functions of mitosis and cytokinesis.

### Final Answer
**b. Growth, tissue repair, and sometimes asexual reproduction**
