Why are organisms made up of many
SMALL cells rather than one large cell?
Materials (food, water, waste) move in and out of smaller cells more efficiently

What is the division of a cell’s nucleus to form 2 nuclei that each have a full set of chromosomes called?
Mitosis

46

What are the 3 reasons that cells divide?
Growth, Repair and
Reproduction

Mitosis is the first part of cell division, what is the second part called?
Cytokinesis
CYTO=Cell
KINET=Move
Separation of cytoplasm

What happens in the cell during anaphase?
Sister chromatids move AWAY to opposite poles

Define cell cycle
The sequence of phases in the life of a cell
Copyright © 2004 Glenna R. Shaw & FTC Publishing
What happens during telophase?
New nuclei form and cytokinesis begins

How is cytokinesis different in plant cells and animal cells?
Animal cells=Cleavage
Furrow
Plant cells=Cell

Interphase
Copyright © 2004 Glenna R. Shaw & FTC Publishing
What is the job of the centromere?
It is a protein disk that attaches two sister chromatids
Copyright © 2004 Glenna R. Shaw & FTC Publishing
G1, S and G2 are collectively called…
Interphase
Copyright © 2004 Glenna R. Shaw & FTC Publishing
What stage does
DNA replication take place in?
S phase of interphase

What happens to the rate of mitosis when you have a cut that needs to heal?
The rate of mitosis increases
