Cells In Microscope Flashcards
Cell membrane
Allows substance to pass in and out of the cell
Cytoplasm
Watery 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 cells)gives strength to the cell
Chloroplast
(Only in plant cells)contains chloroplast to help make food
Base
Keeps microscope stable
Stage and stage clips
Hold the slide in place
Light source
A built in lightbulb or mirror that lights up the specimen
Diaphragm
Controls the amount of light passing through the spectrum
Objective lens
Magnifies the specimen by different factors (4x 10x 40x)
Eyepiece lens
Magnifies the specimen usually by a factor of 10x
Coarse focus wheel
Bring the image to a rough focus
Fine focus wheel
Brings the image to a sharp focus
Micrograph
And image formed when using an electron microscope
Mitochondria and ribosomes
Can be seen with an electron microscope but cannot be seen with a light microscope
Electron microscope
Used to study thing in more detail. A beam of electrons is passed through a specimen
Organelle
Structure in a cell that carries out a particular role
Cell
Made up of organelles different cells do different jobs
Tissue
Groups of cells the that works together e.g blood is made up of red and white blood cells plasma and platelets
Organ
Group of tissue the work together
System
A group of organs that work together
Organisms
An individual that has many systems that work together
