Eukaryotic Cells
Do all cells have the same structure?

An efficiency apartment is a one-room apartment. This one room is where you
sleep, eat, shower, and entertain your guests. It all happens in one room. I t is a
simple way of living in a small space. A mansion is a large, complex living space
with many separate rooms. There are rooms for cooking, eating, sleeping,
bathing, reading, watching TV, entertaining guests, exercising, and storage. The
rooms in a mansion are constructed for the specific things you would like
able to do. You can live in simple efficiency or complexity. Fn this activity
be looking at cells that are as simple as a one-room efficiency apart- ment or as
complex as a mansion.

2. What is represented by the small dots found in each of the bacteria cells?
Ribosomes
3. What is the name of the outermost layer that forms a boundary around the
outside of each cell?
Cell Wall
4. How is the DNA described and what does this mean?
The bacteria is free floating which implies that DNA can move around
anywhere within the cell

5. All the internal structures are suspended (floating) in what substance?
Cytoplasm
6. One of the bacteria in Model 1 has a tail-like structure.
a. What is this structure called?
Flagellum
b. What might be the purpose of this structure?
It helps bacteria move around
c. Based on your answer to the previous question, what might you infer
about the absence of this structure in the other two bacteria cells?
They don't move around they just stay in one place so they don't
need flagellum

shape} between an animal and a plant cell.
Only plant cells have chloroplast, large
permanent vacuole, and cell wall animals do not
