Question 18

The figure given alongside was shown to students of class 10 in the laboratory under a compound microscope. They were told to observe the slide, identify the stage of mitotic cell division and mention the number of chromosomes which would be found in the daughter cells. Which of the following will be the correct response?

  1. Anaphase, 8 chromosomes
  2. Metaphase, 8 chromosomes
  3. Anaphase, 4 chromosomes
  4. Telophase, 4 chromosomes
Answer

Anaphase, 4 chromosomes

Reason — During mitosis the chromosome number remains the same, and in anaphase the sister chromatids move towards opposite ends. During this phase, in animal cell, the furrow formation starts in the cell membrane at the middle by which the cytoplasm will divide after mitosis.
