Cell membrane!
Allows substance to pass in and out of the cell.
Cytoplasm!
Watery fluid that gives support to the cell.
Nucleus!
Controls the cells activities.
Vacuole!
(Larger and permanent in plants) storage of food,water and waste.
Cell wall!
(Only in plant cell) gives strength to the cell.
Chloroplast!
(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.
Object lens!
Magnifies the specimen by different factors (x4,x10 and 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.
Electron microscope!
*Used to study things in more detail.
*A beam of electrons is passed through a specimen.
Micrograph!
An image formed when using an electron microscope.
Mitochondria and ribosomes!
Can be seen with and electron microscope, but cannot be seen with a light microscope.
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 that work together e.g. blood is made of red and white blood cells, plasma and platelets.
Organ!
Group of tissues that work together.
System!
