Question

Select the INCORRECT statement from the following about mitosis.

• A. Each cell called mother cell divides to form two identical daughter cells.
• B. The daughter cells have half the number of chromosomes as mother cell.
• C. It helps in growth and repair of tissues in organisms.
• D. Cells divide for growth.

Answer 1

Answer:

B. The daughter cells have half the number of chromosomes as mother cell.

Mitosis

Understanding Mitosis

• Mitosis is a fundamental process of cell division in eukaryotic organisms. It results in two daughter cells that are genetically identical to the parent cell.

• This process is crucial for growth, repair, and asexual reproduction in multicellular organisms.

Key Features of Mitotic Division

• Chromosome Number: During mitosis, the chromosome number in the daughter cells remains the same as in the parent cell. This is often referred to as equational division. If the parent cell is diploid (2n), the daughter cells will also be diploid (2n).

• Purpose: Mitosis ensures that each new cell receives a complete set of chromosomes, maintaining genetic consistency throughout an organism's life.

• Stages: Mitosis involves several distinct phases: Prophase, Metaphase, Anaphase, and Telophase. Each phase has specific events related to chromosome condensation, alignment, separation, and decondensation.

Distinction from Meiosis

• It is important to differentiate mitosis from meiosis. Meiosis is a type of cell division that produces gametes (sperm and egg cells).

• Meiosis involves two rounds of division and results in four daughter cells, each with half the number of chromosomes as the parent cell (haploid, n). This reduction in chromosome number is essential for sexual reproduction.
