Cell Division and Mitosis

Cell Division

process in which a cell divides into two new cells.

What is reason 1 for why cells need to divide?

living things grow by producing more cells and not because cells grow in size.

What is reason 2 for why cells need to divide?

repair of damaged tissue

What is reason 3 for why cells need to divide?

if a cell gets too big, it can’t get enough nutrients into the cell and waste out of the cell because the cell’s volume increases at a faster rate than the surface area, which is the cell membrane.

This is a disadvantage because when we have smaller cell membrane compared to the volume, the membrane cannot keep up with the cell’s demands.

What is mitosis?

a form of sexual reproduction in which the two ne cells produced are genetically identical to the original cell (parent cell)

What is binary fusion?

mitosis in bacteria

How does cell division work in prokaryotes?

bacteria reproduces asexually by binary fusion.
