Why is Cell Division Important
100
Why do Cells divide?
Cells divide to because they need to stay the size they are
100
Define Cell divison
The division of a cell into two daughter cells with the same genetic material.
100
Define Cell cycle
The series of events that cells go through as they grow and divide.
100
Define Cytokinesis
Division of the Cytoplasam
100
How long does mitosis take?
Between 30 minutes and 2 hours
200
Define Mitosis
The division of the nucleus
200
True or False? The Daughter cells created in cell division are different from each other.
False

3 things happen in during the cell cycle. Name them.
A cell grows,The cell prepares for division,Cell divides
200
When does Cytokinesis occur?
Cytokinesis usually occurs at the same time as telophase
200
True or False? The two daughter cells are identical to the mother.
True
300
Where is the for the cell to function located?

At the end of mitosis,_(1)____have been formed.Each nucleus has an identical set of ___(2)____
(1) Two Nuclei (2)Chromosomes
300
What is the result of mitosis in unicellular plants and animals
It results in new offspring by asexual reproduction
400
_______ must constantly be crossing the membrane in order to leave the cell.
Waste products
400
Each daughter cell is _______ the size of a human cell,but immediately starts growing.
Half
400
During cell division,the Mitosis phase consists of 4 stages. Name them in order
Prophase,Metaphase,Anaphase,Telophase
400
In animal cells,a _______pinches the cell membrane inward until the cell is pinched into two separate cells.
Cleavage Furrow
400
Mitosis in Multi cellular organisms results in the repairs and ______ of the organism.
Growth
500
As the cell grows,the __(1)___ of the cell increases much more rapidly than the ___(2)___of the cell membrane.
(1) Volume (2) Surface area
500
How many pairs of chromosomes do cells have?
23 pairs
500
Interphase takes up __% of the cells life
90%
500
Why is it not possible for the cell to pinch inward in plants?
Plant cells have a rigid cell wall
500
What does mitosis insure?
Mitosis insures the new cells will be able to carry on the same functions as the mother cell.
