Question

Best stage to observe shape, size and number of
chromosomes is
(a) interphase (b) metaphase
(c) prophase (d) telophase

Answer 1

Best stage to observe shape, size and number of  chromosomes is Metaphase.

Option (b)

Explanation:

• Metaphase is the second phase of the cell division after prophase, and it is followed by anaphase and telophase.
• During metaphase the chromatin fibres which is generally found loosely held in the cell starts to condense.
• It becomes very condensed, short and thick during the metaphase and that's why they are easily viewed by the microscope.
• Also they are aligned to the middle of the cell called the equatorial plane which makes them easier to be observed.
• Therefore, one can observe the shape, size and number of chromosomes best during the metaphase.
