During mitosisa)One cell enlarge into one cellb)One cell divide into two cellsc)One cell divide into four cellsd)One cells divide into eight cellsCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Yeah!!! In mitosis, a cell divides in 2 daughter cells which contains same chromosome complement and ensures equal distribution of genetic material. In mitosis, the division of nucleus and cytoplasm occurs only once. hope it helps :-)

Answer

B

Answer

B ans

Answer

C

Answer

Mitosis is a equational cell division . hence chromosomes share equally to 2 cell during mitosis ...

Answer

During mitosis, one cell divides into two cells. This is a crucial process in the life cycle of a cell and plays a vital role in growth, development, and tissue repair in multicellular organisms. Mitosis is a type of cell division that occurs in somatic cells, which are non-reproductive cells. It is important to note that mitosis is different from meiosis, which is involved in the production of gametes (reproductive cells).

Mitosis can be divided into several stages, including prophase, prometaphase, metaphase, anaphase, and telophase. Each stage has specific characteristics and events that occur.

1. Prophase:
- The chromatin, which is the DNA in a loosely packed form, condenses and becomes visible as chromosomes.
- The nuclear membrane starts to break down.
- The centrosomes, which are responsible for organizing the microtubules, move to opposite poles of the cell.
- The microtubules called spindle fibers start to form.

2. Prometaphase:
- The nuclear membrane completely breaks down.
- The spindle fibers attach to the centromeres of the chromosomes.
- The chromosomes start to move towards the center of the cell.

3. Metaphase:
- The chromosomes align at the center of the cell, forming a metaphase plate.
- The spindle fibers attach to each chromosome's centromere.

4. Anaphase:
- The spindle fibers shorten and pull the sister chromatids apart.
- The separated chromatids are now called daughter chromosomes and move towards opposite poles of the cell.

5. Telophase:
- The daughter chromosomes reach the opposite poles of the cell.
- Nuclear membranes start to form around each set of chromosomes.
- The chromosomes begin to uncoil and return to their chromatin form.
- The spindle fibers disassemble.

Finally, cytokinesis occurs, which is the division of the cytoplasm and the formation of two separate daughter cells. In animal cells, a contractile ring composed of actin and myosin filaments contracts, pinching the cell membrane inward and dividing the cytoplasm. In plant cells, a cell plate forms in the center of the cell, eventually developing into a new cell wall that separates the daughter cells.

In summary, during mitosis, one cell divides into two cells through a series of stages. This process ensures the equal distribution of genetic material and the formation of genetically identical daughter cells.

Answer

Yes, that is correct because, during mitosis, a single-parent cell divides into two daughter cells, each containing the same number of chromosomes as the parent cell.
