13. Please complete the following magnification calculation. You are observing a specimen using a
compound microscope like the one above. This microscope has a 10x magnification in its ocular
lens, a 5x magnification for its low power objective, a 10x magnification for its medium power
objective, and a 50x magnification for its high power objective. What is the total magnification
of the specimen if you are using the medium power objective to view it? Please show your
work.
14. All living things on earth are made of cells. Living things can be made up of just one cell or of
many, many, cells. Cells are too small to be seen without a microscope. Although they are very
small, all cells are able to respond to changes in their environment, grow, develop, reproduce,
and use energy.
a. Organisms that are made of many many cells are called
____________________________________-cellular organisms.
b. Organisms that are made up of just one cell are called
___________________-cellular organisms.
15. ______________ True or False: Prokaryotic organisms are unicellular organisms while
eukaryotic organisms can be BOTH multicellular and unicellular organisms.
16. Cells are the basic unit of structure and function of living things, but they are made up of
smaller parts, and they also come together to make larger parts. Please list from LARGEST to
SMALLEST the following units of biological organization: cells, atoms, organisms, organ systems,
molecules, tissues, organs.
Largest: _____________________________________  ___________________________________ 
_____________________________________  _____________________________________ 
_____________________________________  _____________________________________ 
_____________________________________ Smallest
For example: Muscle cells and epithelial cells make up heart tissue which makes up the heart organ,
the heart is an organ in the circulatory system and the circulatory system is an organ system that
makes up a part of an organism like a human!
17. _________________ True or False: Humans are multicellular organisms.
Now Let’s talk about ORGANELLES!
18. Please match the following names of
organelles to their definition
1. Cell membrane _____________
2. Nucleus _____________
3. Mitochondria _____________
4. Cell wall _____________
5. The golgi apparatus _____________
6. Chloroplast _____________
7. Vacuole _____________
8. Cytoplasm _____________
9. Ribosome _____________
10. Endoplasmic reticulum _____________
11. Lysosome _____________
A. This organelle is made of a series of
passageways that transports proteins
through the cell.
B. This organelle produces proteins from
amino acids by translating the DNA.
C. The organelle contains digestive enzymes
inside it to break down the things that the
cell does not need.
D. This organelle receives proteins from the
endoplasmic reticulum, packages them up
in sacs and distributes them to where they
need to go.
E. This organelle provides rigidity and
protection for the plant cell and is not
found in animal cells. This organelle
surrounds the plant cell’s plasma
membrane.
F. This organelle has a double membrane
that functions to help the cell make
energy. This organelle is also known as the
powerhouse of the cell.
G. This organelle is the protective outer layer
of the cell. It lets certain things into the cell
that it needs and keeps other things out
that it does not need. It is semi-permeable.
H. This organelle contains chlorophyll and
uses sunlight and nutrients to make food
for the cell. This organelle is only found in
plant cells.
I.
This organelle stores nutrients, or water in
the cell in a sac. This organelle is often
much larger in a plant cell than an animal
cell.
J.
This organelle is the control center of the
cell. It contains all of our genetic
information in the form of DNA. This DNA
tells the cell how to function.
K. This organelle is the watery medium that
everything in the cell floats in. This is like
the atmosphere of the cell.
19. The cell membrane acts as a semi-permeable barrier which allows or prevents certain substances from
coming in or out. The cell membrane can do osmosis and diffusion.
Osmosis is the movement of ________________________ across a semi-permeable membrane.
Diffusion is the movement of ________________________ across a semi-permeable membrane.
20. Use the following terms to fill in the blanks.
twisted ladder
nucleus
protein
ribosomes
nucleotides
parents
children
Genes
job
The DNA contained in the __________________________ of eukaryotic cells (and in the cytoplasm of
prokaryotic cells) carries the instructions for how each individual cell should grow and develop. DNA holds
the instructions or “code” that _________________________________ will read and use to make proteins
out of amino acids. DNA is made up of repeating units of building blocks called
_________________________________________. The shape of DNA is like a
________________________________ __________________________ also known as a double helix.
Chromosomes get passed on from _________________________ to __________________________ and
carry genes. ___________________________ are short sections of DNA. Each specific gene codes for a
specific _____________________________. When a gene is turned on, the ribosome will read the short
section of DNA and create a protein from what it read. Each different type of cell is able to do its specific
________________ because of the different proteins they have.

c. __________ This cell is tiny
d. __________ This cell has ribosomes
