Questions and Answers

What is a key characteristic of cells that undergo mitosis?

They are haploid cells.
They are usually larger than other cells.
They can only reproduce asexually.
They contain two sets of chromosomes. (correct)

What could happen if cells spent more time in mitosis than in interphase?

It could lead to uncontrolled cell growth or cancer. (correct)
The efficiency of DNA replication would increase.
Cell growth and preparation for division would be enhanced.
Cellular respiration would become more effective.

Study Notes

Mitosis: Cell Division

Mitosis is a cell division process that produces body cells.
Certain cell types, like nerve and muscle cells, do not undergo mitosis.
Mitosis is essential for growth and repair in the body.
It ensures that cells have the correct number of chromosomes.
Mitosis is part of the cell cycle. Interphase is the larger portion of the cell cycle.
If mitosis occurred more than interphase, cells would be in a constant cycle of division.

Importance of Mitosis

Mitosis is crucial for growth and repair in the body.
It ensures cells have the correct number of chromosomes.

Chromosome Structure

Chromosomes are made of proteins and DNA.

Mitosis Process Stages and Outcomes

Mitosis begins and ends with diploid cells, meaning they have two sets of chromosomes from each parent.
In humans, diploid cells have 46 chromosomes in each cell.
Mitosis ensures that each new cell created has the same number of identical chromosomes.
Illustration shows that cells created have identical chromosomes.
