Mitotic division is also called equational division because

Options

A. Chromosome number in daughter cell is same
B. Chromosome number in daughter cells and parental cell is same
C. Amount of DNA is same in both the daughter cells
D. Amount of DNA is same in both daughter and parental cell

Answer

**Step-by-Step Solution:**

1. **Understanding Mitosis**: Mitosis is a type of cell division that results in two daughter cells that are genetically identical to the parent cell. This process is crucial for growth, development, and tissue repair in multicellular organisms.

2. **Chromosome Replication**: Before mitosis begins, the chromosomes in the parent cell replicate. This means that each chromosome is duplicated, resulting in two identical copies called sister chromatids.

3. **Equational Division**: During mitosis, these sister chromatids are separated and distributed equally into the two daughter cells. This ensures that each daughter cell receives the same number of chromosomes as the parent cell.

4. **Chromosome Number**: If the parent cell is diploid (having two sets of chromosomes), each daughter cell will also be diploid after mitosis. Therefore, the chromosome number in each daughter cell is the same as that in the parent cell.

5. **Conclusion**: Because the chromosome number remains constant (equivalent in both daughter cells and the parent cell), mitotic division is referred to as "equational division."

**Final Answer**: Mitotic division is called equational division because the chromosome number in each daughter cell is the same as that in the parent cell.
