1.) In your own words, write a
definition for ribosome,
lysosome, and cell wall.
A
ribosome is an organelle without a membrane
that makes proteins from amino acids.
 A lysosome is a special kind of vesicle that
contains enzymes to break down worn out
organelles.
 The cell wall is the outer most layer of plant,
algae and fungal cells

2.) Which of the following are
found mainly in animal cells?.
 A.)
mitochondria
 B.) lysosomes
 C.) ribosomes
 D.) Golgi complex
1-2
3.) What is the definition of a
Golgi Complex? What is the
function of the endoplasmic
reticulum?
 The
Golgi complex is a system of closed
off smooth ER that stores and packages
proteins for the cell.
 The ER is a system of passageways that
moves substances such as lipids and
proteins around the cell.

4.) Making Comparisons:
Describe three ways in which a
plant cell is different from an
animal cell.
A
plant cell has a cell wall and
chloroplasts while an animal cell does not.
 A plant cell usually has a large vacuole
instead of the many small lysosomes that
would be found an animal cell.

5.) Applying Concepts: Every
cell needs ribosomes. Explain
why?
 Every
cell needs ribosomes because
ribosomes make proteins. Most of the
organelles of a cell are made of these
proteins that are essential for life.

6.) Predicting consequences: A
certain virus attacks the
mitochondria of cells. What would
happen to a cell if al of its
mitochondria were destroyed?
 The
cell would die due a lack of energy,
because the mitochondria are the source
of a cells energy.
1-2
7.) Expressing Opinions: Do you think
that having chloroplasts gives plant
cells an advantage over animal cells?
Support your opinion.
 Having
chloroplasts is definitely an
advantage that plants have over animals.
Chloroplasts allow plants to produce their
own food from water, carbon and
sunlight.
 Animals need to consume other
organisms in order to survive.

8.) Is this a diagram of a plant cell
or animal cell? Explain how you
know.
 This
is an example
of an animal cell
because there is
no cell wall and
there are
numerous
mitochondria.
