Which organelles store food and
other materials needed by the cell?

What is the total magnification of a microscope with
two lenses when one lens has a magnification of 20,
and the other lens has a magnification of 10?
10
30
200
2000
CORRECT!
You multiply the magnification
of each lens to get
the total magnification.
WHOA!
Think about it
again!
Which of the following statements is NOT part
of the cell theory?
Cells are the basic unit of structure and function in living things.
All cells are produced from other cells.
Only animals are composed of cells.
All living things are composed of cells.
You are a great THINKER!

What is the function of the cell
membrane?
To protect and support the cell
To perform different functions in each cell
To control what enters and leaves the cell
To form a hard outer covering for the cell
HINT:
A cell membrane is just
like a dog gate. Now try
again.

Why is water important to a cell?
Water is the main ingredient in DNA.
All proteins require water to function.
Most chemical reactions in cells require water.
Water is an essential organic compound for the body.
HOORAY !
It is a good
thing that you
get to try
again!

from an area of higher concentration to an area of
lower concentration?
collision

What is the function of a cell wall?
To protect and support the cell
To perform different functions in each cell
To prevent water from passing through it
To prevent oxygen from entering the cell
YOU ARE RIGHT!
The cell wall is like a skeleton.
It protects and supports.

discover and learn about?
plants
skin
animals
cells
WONDERFUL
!
OOPS!
Here is a hint.
Microscopes are
used to look at very
small objects. Hope
that helps.

You are right!
My name is
Leeuwenhoek
and I observed
bacteria.
