The curved piece of glass in the microscope does the magnifying.
What is the lens?
100
One way that bacteria are harmful:
They make people sick, spoil food, etc.
200
a blood cell
What is a eukaryote?
200
Gel-like substance inside the cell that everything floats around in.

A microscope that uses light and lenses to create an image.
What is a light microscope?
200

300
a blueberry cell
What is a eukaryote?
300
Long, whip-like attachment that the cell uses to move around.
What is flagellum?
300
Prokaryotic cells are smaller than eukaryotic cells
True
300
An extremely strong microscope that can create very detailed images, but is too large and expensive to have in this classroom.
What is an electron microscope (or scanning electron microscope)?
300
The major difference between prokaryotic and eukaryotic cells:
Eukaryotes keep their DNA in a nucleus and prokaryotes have their DNA floating freely in the cytoplasm.
400
streptococcus (think strep throat)
What is a prokaryote?

What is the coarse adjustment, then the fine adjustment?

What is a eukaryote?
500
tiny hair-like structures that help the bacteria sense its environment and stick to surfaces.
What are pili (or pilus)?
500
ALL Eukaryotes have a nucleus.
True
500
The total magnification when the eyepiece lens is 10x and the objective lens is 4x.
What is 40x?
