mitochondria ribosome nucleus
chloroplast Golgi bodies vacuoles
Which organelle is the control center of the
cell?
Yeah! You’re on a roll!
Go to next question.Cell with nucleus highlighted. Paul Fuqua. 2005. unitedstreaming. 6 February 2006

That is That is Incorrect!Incorrect!
mitochondria ribosome nucleus
chloroplast Golgi bodies vacuoles
Which organelle produces most of
the energy needed by a cell?
Go to next question.
So cool!!YOU ARE DOING GREAT!

WHOA! Think about it
again!
mitochondria ribosome nucleus
chloroplast Golgi bodies vacuoles
Which organelles produce proteins in
the cell?
Go to next question.
WOW!YOU ARE DOING GREAT!

around and THINK about
it.
mitochondria ribosome nucleus
chloroplast Golgi bodies vacuoles
Which organelles store food and other materials needed by
the cell?
WOW!YOU ARE DOING GREAT!
OOPS! I wonder if you plug in your brain
if it would help. Click the arrow

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.
All living things are composed of cells.
Only animals 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 form a hard outer covering for the cell
To control what enters and leaves the cell
WONDERFUL !
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.
Water is an essential organic compound for the body.
Most chemical reactions in cells require water.
HOORAY !
It is a good thing that you
get to try again!
Which term refers to the movement of molecules from
an area of higher concentration to an area of
lower concentration?collision
diffusion
concentration
active transport
You are going to Hollywood!You will be the next Science Idol!

Which term refers to the movement of water molecules through a
selectively permeable membrane?osmosis
engulfing
passive transport

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

The invention of the microscope made it possible
for people to discover and learn
about?
plants
skin
cells
animals
WONDERFUL !
OOPS!Here is a hint.
Microscopes are used to look at very small objects. Hope that
helps.

Which of these scientists was the first person to observe
what are now called bacteria?
Ernst Ruska
Hans Janssen
Anton von Leeuwenhoek
Robert Hooke
You are right!
My name is Leeuwenhoe
k and I observed bacteria.
