12
cell membrane acts like a film of oil because the fatty acids keep slipping around each other.
False. The fatty acids are very firm.
true
False. Only a few cells are made of fatty acids
False. Change cell membrane to cell wall
13
a Russian Bacteriologist. that accidentally observed the animal cells dividing
Albert Einstein
Robert Hooke
Theodor Schwann
Rudolf Virchow
14
Why do our body cells have such different shapes?
The cells have different jobs
The different shapes help fight disease
to use different nutrients
to make people different from each other
15

Skin
Bone
16
Published that all parts of a plant were made of cells
.
Matthias Schleiden
Theodor Schwann
Rudolph Virchow
Robert Hooke
17
The cell membrane is composed of two layers of fatty acids.
False. Change 2 layers to 1 layer
False. Change fatty acids to carbohydrates
True
False. Change Cell membrane to Cell Wall
18
Could different cells in your body do different jobs if they were permeable to the same things?
No
Yes
19
Who is this?
Albert Einstein
Matthias Schleiden
Robert Brown
Robert Hooke
20
Identify this man.
Zacharias Janssen
Anton Van Leeuwenhoek
Rudolf Virchow
Robert Brown
21
Because of all of our cells are human cells, they are all permeable to the same molecules.
Yes. This is True
Change "are human cell" to growing cells
False. Different cells need different things to do their job
False. Change human cells to animal cells
22
Bricks and cells are alike because they are both non-living things.
False. There is no connection between bricks and cells
False. Cells are living things
Yes. This is true
23
Who is this?
Zacharias Janssen
Theodor Schwann
Matthias Schleiden
Robert Brown
24
What is this?
These are Bone Cells
These are Nerve Cells
These are Blood Cells.
These are Female Egg Cells
25
Which statement below is NOT part of the cell theory?
Cells come from other cells.
The cell is the basic unit of life
Big creature has big cells, small creature has small cells.
All living things are made of cells.
26
Human Body Cells are separated from the interstitial fluid by a tough cell wall.
False. change "tough cell wall" to a cell membrane
False. Change tough to soft and tender
False. There is no separation between the cell and outside
True
27
Tell me what this cell is!
This is Blood
This is Bone
This is not a human cell
This is Skin
28
Name the model that has been created to represent the cell membrane
.
The Virchow Model
The Fluid Mosaic Model
The J.J. Thompson Model
The Hooke Model
29
Why is the cell membrane called a “selectively” Permeable membrane?
It stops all molecular movement across the membrane.
It lets all things pass through
It lets certain things pass through when there is a need
The cell membrae keeps the cytoplasm from leaking out.
30
Identify this scientist
Zacharias Janssen
Robert Hooke
Rudolph Virchow
Robert Brown
31
He was the first to observe cells. He was actually looking at the cell walls.
Rudolf Virchow
Anton Van Leeuwenhoek
Robert Brown
Robert Hooke
32
Who?
Anton Van Leeuwenhoek
Zacharias Janssen
Robert Hooke
Rudolf Virchow
33
Why is the cell theory considered the CornerStone of Biology?
It was authorized by the church as devine.
It was developed by the first biologist.
Many have tried to prove it wrong
All biology is based on the cell theory
34
Name the substance that surrounds body cells
Water
Ground Matrix
Blood
Interstitial Fluid
35
A particular cell may let a molecule pass through the membrane today, but stops it tomorrow.
False. Change particular to specific cells only
False. it can pass through anytime
This is True
False. Change molecule to atoms
36
How does the plasma membrane function in maintaining homeostasis?
It totally prohibits osmosis
It changes fats into proteins.
It controls what enters and leaves the cell.
It gives the cell its shape
37
What type of environment are cells found in?
A fluid environment
In a hard, calcium matrix of bone
Surrounded by body fat
In a gel like environment
38
Why is it necessary for scientist to keep adjusting the cell membrane model?
New technology gives us new information
The cell membrane keeps evolving
No two cell membranes are designed alike.
The cell membrane from a large cell requires a larger model.
39

False. Alike because they are both made of the same thing
True
False. Alike because they are the same size
False, you cannot build with cells! they are too small
