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?

The correct answer is interphase.

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.  

meiosis is the first to occur after the nuclei of opposite of opposite mating types fuse
