Cells
#1
The cell theory states that all cells are the smallest
Unit of life, all organisms are made up of cells, and…
A: All cells contain a
B:
nucleus
Cells need a
C: membrane to protect it
from its environment
All cells come from
Pre-existing cells
D:
Cells are gnarly!
B
#2
Cells show emergent properties meaning…..
They stick together to
A: form multi cellular
organisms
They are the basic
B: building blocks or all
living things.
The whole is greater
C: than the sum of the
parts.
D: perform similar
They have evolved to
functions

#3
The size of a molecule is 1nm, and the size of a
Virus is 10nm, what are the sizes of prokaryotic and
a eukaryotic cell?
A: 1µm, and 100µm
B:
100nm, and 1000µm

#4
Why is surface area to volume ratio important to
Limiting a cell’s size?
When the cell grows
A: the surface area
increases more rapidly
than the volume
Metabolism depends
B: on the volume of the
cell
As it grows the ratio
decreases not allowing the
cell to receive enough
nutrients or expel enough
waste
As it grows the ratio
increases not allowing the
cell to receive enough
nutrients or expel enough
waste

#5
Cellular differentiation is important to multi-cellular
Organisms because….
A:
Cells performing different
functions and cooperate
to allow an organism to
perform functions beyond
one cell type.
Many functions allow a
C: cell to divide at faster
rates
B:
D:
They perform different
functions based on
chemical responses
Cells are not
differentiated
A
#6
Stem cells are used for therapeutic purposes because
A: They can grow very

fast
C: Have the ability to
differentiate
D:
They are easy to
obtain
They contain all the
necessary genetic
information
