A cell that comprises two kinds of chromosomes is called _______ .

Options

A. Diploid
B. Haploid
C. Polyploid
D. Biploid

Answer

To answer the question "A cell that comprises two kinds of chromosomes is called _______," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Chromosomes**: First, we need to understand what is meant by "two kinds of chromosomes." This typically refers to the presence of paired chromosomes, where one chromosome is inherited from each parent.

2. **Identifying the Term**: The term that describes a cell with two sets of chromosomes is "diploid." In diploid cells, chromosomes exist in pairs, which means there are two homologous chromosomes for each type.

3. **Evaluating Other Options**:
- **Haploid**: This term refers to cells that contain only one set of chromosomes (one of each type), which is not what we are looking for.
- **Polyploid**: This refers to cells that have more than two sets of chromosomes (e.g., triploid, tetraploid), which also does not fit the description of having just two kinds of chromosomes.
- **Ploidy**: This is a general term that refers to the number of sets of chromosomes in a cell, and it includes diploid and polyploid cells. It is not a specific answer to the question.

4. **Conclusion**: Based on the definitions and evaluations above, the correct answer to the question is "diploid."

### Final Answer:
A cell that comprises two kinds of chromosomes is called **diploid**.
