Question

1. What type of cell division is observed in onion root tips and
why?​

Answer 1

Answer:

It is because of the meristematic cells that are situated in the tip of the roots that render the most desirable and suitable raw material to study the different stages of mitosis.

Answer 2

Cell division observed is mitosis due to meristematic cells.

• There are eight key pairs of chromosomes in an onion. These chromosomes are easier to accurately observe as they condense.
• As the roots lengthen to capture water and minerals from the earth, the root tip cells divide rapidly.
• As a result, chromosomal distribution can be used to typically distinguish between distinct phases of mitotic cell division.
