The signigicance of Meiosis is that it -

Options

A. Produce four cells having chromosomal number equal to mother cell
B. Occurs in all types of cells
C. Maintains the constant Chromosomes number to a particular species
D. Growth of animal body ograns

Answer

### Step-by-Step Solution:

1. **Understanding Meiosis**: Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the formation of four genetically diverse daughter cells. This process is essential for sexual reproduction.

2. **Analyzing the Options**:
- **Option 1**: "Produce four cells."
- While meiosis does produce four cells, this statement is misleading because it does not mention that these cells have half the chromosome number of the original cell.
- **Option 2**: "Occurs in all types of cells."
- This is incorrect. Meiosis specifically occurs in germ cells to produce gametes (sperm and eggs), not in all cell types.
- **Option 3**: "Maintains the constant chromosome number to a particular species."
- This is correct. Meiosis ensures that when gametes fuse during fertilization, the resulting offspring have the same chromosome number as the parents, preventing an increase in chromosome number with each generation.
- **Option 4**: "Growth of animal body organs."
- This is incorrect because growth and repair of body tissues are primarily accomplished through mitosis, not meiosis.

3. **Conclusion**: The significance of meiosis is best captured by option 3, which states that it maintains the constant chromosome number within a species.

### Final Answer:
The significance of meiosis is that it maintains the constant chromosome number to a particular species (Option 3).
