What organelle is the red
arrow pointing to?
The endoplasmic reticulum
How would you describe a
mitochondria?
It has a rod-like shape and
makes the energy for the
cell.
What are small round
structures in cells that break
down large food particles
into smaller ones and recycle
old cell parts called?
Lysosomes
What is the name and function
of the organelle the red arrow is
pointing to?
It is the nucleolus. It’s job
is to produce ribosomes.
What is the name of the
process animal cells go
through to make more of
themselves?
Mitosis
What is the
name and
function of the
organelle the
red arrow is
pointing to?
It is the cell wall. The job of
the cell wall is to support
and protect the plant cell.
What are chloroplasts
responsible for in the cell?
They use photosynthesis
to make food for the cell.
There is an
organelle
missing from
this picture of a
plant cell. What
is it?
The chloroplast is missing.
Does a plant cell
have mitochondria?
Why or why not?
Yes. Both plant and animal
cells have mitochondria.
They need to be able to
release energy from food.
Why do plants wilt
and droop?
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.
Where is the cytoplasm
located in this picture?

What is the job of
the cell
membrane?
It controls what goes in and
out of the cell, maintains the
chemical balance of the cell.
What is responsible
for making a girl’s
eyes blue?
It would be the chromatin.
The chromatin inside the
nucleus contains DNA, which
are the genetic instructions for
a cell.
A tiny cell structure
that carries out a
specifics function
within a cell is
called what?
Organelles
How many chromosomes do
humans have?
46 total chromosomes.
What is diffusion?
Diffusion is the movement of
molecules across a
membrane from an area of
high concentration to an area
of low concentration.
What is osmosis?
It is the movement of
WATER molecules from an
area of high concentration
to an area of low
concentration.
What is the difference
between passive transport
and active transport?
Passive transport requires no
energy but active transport
requires the cell to use
energy.
Name two examples of active
transport.
Protein transport
and
Engulfing
Look at the picture. What is
going on in the cell…passive or
active transport? How do you
know?
Water
Molecule
Cell
Membrane
Sugar
Molecule
This is a picture of passive
transport. The sugar can’t 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.
What part of a cell
has a function that
can be compared to
our brain? Why?
The nucleus. It controls all
the functions of the cell just
like our brain controls all the
functions of our body.
What would happen if you
put a red blood cell into a
beaker of water with a
high salt concentration?
Why?
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.
What does the cell theory
state?
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.
What two scientists
contributed to the cell
theory?
Anton van Leeuwenhoek
Robert Hooke’s
microscope (there are
no pictures of him)
What are three
differences between
plant cells and
animal cells?
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.
