Types of cells
The two types of cells that ALL living things are divided into are...
Prokaryotic and Eukaryotic
The lens of a microscope bends the_________ towards the eyes in order to make an object look magnified or, essentially, bigger.
Light
Organelle is a word that means...
Little organs
This cell structure, found only in plant cells, controls what exits and enters the cell and gives the cell rigid support and structure.
CELL WALL
What part of the microscope holds the slide in place?
Stage Clips
Eukaryotic cells are known to have a____________ where the DNA is kept.
Nucleus
What would the total magnification be if you were looking through an ocular lens of 10X and an objective lens of 30X?
300X
Eukaryotic cells are different from prokaryotic cells because their DNA is housed in a
Nucleus
Sometimes described as a flattened stack of sacs or a stack of plates, this organelle can sometimes be covered in ribosomes (sometimes not) and serves as a network of membranes for molecules to passthrough.
ENDOPLASMIC RETICULUM
What part of the microscope controls the amount of light used to see the specimen?
Diaphragm
Prokaryotic cells do not have many of the membrane-covered____________ that eukaryotic cells have.
Organelles
Instead of using light as the source of energy to illuminate a specimen, an electron microscope uses a beam of___________ to magnify an object.
Electrons
Eukaryotic organisms include all living things except...
Bacteria
This organelle is like a little trash collector or recycling organelle. It contains powerful digestive enzymes that break down old organelles and other molecules.
LYSOSOME
What part of the microscope is used for small scale, fine focusing ?
Fine Adjustment
The only organisms classified as prokaryotes are...
Bacteria
If you were looking through a microscope with an ocular lens of 20X and objective lens 20X, it means that whatever specimen you were looking at would be 400________ larger than it really would be with your unaided eye.
times
Eukaryotic cells tend to be much_______in size when compared to Prokaryotic
Larger
A tiny organelle found in plant, animal & bacterial cells, these structures are the protein producing workers of the cell. They can sometimes be attached to the rough ER or floating in the cytoplasm.
RIBOSOMES
What part of the microscope is used for magnifying the object you are viewing often with several levels of magnification?
Objective Lense
THESE are known to be effective for medical use against prokaryotes.
Antibiotics
A compound light microscope uses 2 different ___________ in order to magnify a specimen on a slide.
lenses
The 2 kinds of cells that we studied that are examples of eukaryotic cells were ______ and _________ cells.
Plant and Animal Cells
This organelle is a kind of shipping and manufacturing structure that sends various molecules to other parts of the cell (or out of the cell). It often receives different moleculesfrom the ER (and looks quite a bit like the ER).
GOLGI BODY
What part of the microscope is the source of light and makes objects visible?
Light Bulb
