What organelle is the red arrow pointing to?
3
The endoplasmic reticulum
4
How would you describe a mitochondria?
5
It has a rod-like shape and makes the energy for
the cell.
6
What are small round structures in cells that
break down large food particles into smaller ones
and recycle old cell parts called?
7
Lysosomes
8
What is the name and function of the organelle
the red arrow is pointing to?
9
It is the nucleolus. Its job is to produce
ribosomes.
10
What is the name of the process animal cells go
through to make more of themselves?
11
Mitosis
12
What is the name and function of the organelle
the red arrow is pointing to?
13
It is the cell wall. The job of the cell wall is
to support and protect the plant cell.
14
What are chloroplasts responsible for in the cell?
15
They use photosynthesis to make food for the cell.
16
There is an organelle missing from this picture
of a plant cell. What is it?
17
The chloroplast is missing.
18
Does a plant cell have mitochondria? Why or why
not?
19
Yes. Both plant and animal cells have
mitochondria. They need to be able to release
energy from food.
20
Why do plants wilt and droop?
21
When their vacuoles lose water, they shrink.
This causes the whole cell to shrink. When many
cells start to shrink, the plant begins to wilt
and droop.

24
What is the job of the cell membrane?
25
It controls what goes in and out of the cell,
maintains the chemical balance of the cell.
26
What is responsible for making a girls eyes blue?
27
It would be the chromatin. The chromatin inside
the nucleus contains DNA, which are the genetic
instructions for a cell.
28
A tiny cell structure that carries out a
specifics function within a cell is called what?
29
Organelles
30
How many chromosomes do humans have?
31
46 total chromosomes.
32
What is diffusion?
33
Diffusion is the movement of molecules across a
membrane from an area of high concentration to an
area of low concentration.
34
What is osmosis?
35
It is the movement of WATER molecules from an
area of high concentration to an area of low
concentration.
36
What is the difference between passive transport
and active transport?
37
Passive transport requires no energy but active
transport requires the cell to use energy.
38
Name two examples of active transport.
39
Protein transport andEngulfing
40
Look at the picture. What is going on in the
cellpassive or active transport? How do you
know?
Water Molecule
Sugar Molecule
Cell Membrane
41
This is a picture of passive transport. The
sugar cant move because it is too big to fit
through the holes in the cell membrane. The
water molecules move from high concentration on
the left to low concentration on the right. This
is also known as osmosis.
42
What part of a cell has a function that can be
compared to our brain? Why?
43
The nucleus. It controls all the functions of
the cell just like our brain controls all the
functions of our body.
44
What would happen if you put a red blood cell
into a beaker of water with a high salt
concentration? Why?
45
The red blood cell would shrink. The
concentration of water inside the cell would be
higher then outside, so the water would move out
of the cell causing it to shrink. This is
because of osmosis.
46
What does the cell theory state?
47
1. All living things are made of cells.2.
The cell is the basic unit of structure and
function.3. All cells come from existing cells.

48
What two scientists contributed to the cell
theory?
49
Anton van Leeuwenhoek
Robert Hookes microscope (there are no pictures
of him)
50
What are three differences between plant cells
and animal cells?
51

1. A plant cell has a cell wall and an animal
cell does not.2. A plant cell has a chloroplast
and an animal cell does not. 3. A plant cell
has a regular shape and an animal cell does
not.4. A plant cell has one large vacuole and
an animal cell has a few small vacuoles.5. An
animal cell has lysosomes and plant cells may
not.
