Microscopes and Cells Flashcards
What is a slide in microscopy?
A thin piece of glass or plastic that holds a specimen for examination.
What is the body tube of a microscope?
The part you see through.
What is the eyepiece lens?
The lens that allows you to see through the body tube. It can have different magnifications.
What is the revolving nosepiece?
A rotating platform to change the lens you are looking through.
What is the objective lens?
The lens you will be looking through.
What are stage clips?
They help keep the slide in place.
What is the stage of a microscope?
The flat platform where the specimen is placed for observation.
What is the diaphragm in a microscope?
The mechanical part that focuses light onto the specimen from the light source.
What is the light source in microscopy?
A source of light to help see the specimen better and clearer.
What is the course focus?
The dial that moves the stage up and down.
What is the fine focus?
The dial that moves the stage very lightly for final adjustments.
What is the base of a microscope?
The bottom part of the microscope.
What components are found in both plant and animal cells?
Cytoplasm, Nucleus, Cell membrane, and Mitochondria.
What components are found only in plant cells?
Cellulose cell wall, Vacuole, and Chloroplast.
What is the function of cytoplasm?
It is where the cell’s activities take place.
What does the cell membrane do?
It controls what goes in and out of the cell.
What is the role of the nucleus?
It controls the cell and its functions.
What is the function of mitochondria?
It provides energy for the cell’s reactions.
What is the cell wall?
An outer structure that gives the cell support.
What is a vacuole?
A space within the cytoplasm of plant cells that contains sap.
What is the function of chloroplasts?
They contain chlorophyll and are the site of photosynthesis.
Where is genetic material found?
In the nucleus.
Where does respiration take place?
In the mitochondria and cytoplasm.
