Question

In what stage were most of the onion root tip cells? based on what you know about cell cycle division, what does this imply about the life span of a cell?

Answer 1

The correct answer is interphase.

Step-by-step explanation:

Interphase is the cell cycle stage in which most of the onion root tip cells are present. Interphase is the longest part of the cell cycle as the cell grows and develops here.

It takes place before mitosis and the majority of the development takes place in this stage. The stage comprises all the three G1, G2 and S phase. Thus, it can be said that the cells go through the process of development before it actually begins to proliferate. This shows that the cells in the onion root tips generally spend the majority of their lifespan in the interphase stage.

Answer 2

The correct answer is interphase.

Root tip cells are known cells that have a rapid division to allow the growth and lengthening of the roots

The life of the somatic cell is divided into two major phases: interphase and mitosis.

The interphase is the longest phase in a eukaryotic cell, it is in this phase that the cell must prepare for division, and this by transcribing necessary proteins, replicate and repair the DNA in case of lesions. .

Mitosis is relatively fast, it represents less than a quarter of the life of the cell.
