Parts Of Cells Flashcards
Cell mambrane
Allows substances to pass in and out of the cell
Cytoplasm
Water fluid that gives support to the cell
Nucleus
Controls the cell’s activity
Vacuole
Larger and permanent in plants storage of food water and waste
Cell wall
Only in plant cell gives strength to the cell
Chiorplasts
Only in plant cell contains chlorophyll to help make food
Base
Keeps the microscope stable
Stage and stage clips
Holds the slide in place
Light source
A built in light bulb or mirror that lights up the specimen
Diaphragm
Controls the amount of light passing through the specimen
Objective lens
Magnifies the specimen by different factors (x4, x10, x40)
•
Eyepiece lens
magnifies the specimen, usually by a factor of 10 (x10
Coarse focus wheel
brings the image into rough focus
Fine focus wheel
brings the image into sharp focus
Cell membrane
allows substances to pass in and out of the cell
Cytoplasm
– watery fluid that gives support to the cell
Nucleus
controls the cells activity
Vacuole
(larger and permanent in plants) storage of food, water, wastes
Cell wall
only in plant cell) gives strength to the cell
Chloroplasts
(only in plant cell) contains chlorophyll to help make food
Electron microscope
Used to study things in more detail
A beam of electrons is passes through a specimen
Micrograph
An image formed when using an electron microscope
Mitochondria and ribosomes
Can be seen with an electron microscope but cannot be seen with a light mircoscope
