Made up of many cells. Mutli- = many
The basic unit of structure and function of any living thing.
coarse adjustment knob
Moves the body tube/stage up and down to allow focusing of the image when on low-powered objective lens.
A cell that contains a nucleus and a complex internal structure. An organism that has eukaryotic cells is a eukaryote.
Where you look through. Magnifies the image 10x. Contains the pointer.
fine adjustment knob
Moves the body tube/stage slightly to bring the object into sharper focus. Can be used with any powered objective lens.
hierarchy of living things
Cell-tissue-organ-organ system-multicellular organism: Arranged in order from smallest in size, but the base of all other things - to the largest in size, but composed of everything else.
Controls the amount of light for viewing the slide.
A combination of two or more tissues that work together to perform a specific function.
An instrument that makes small objects look larger. Simple microscope - composed on one lens. Compound microscope - composed of two or more lenses.
Magnify the object. Low-powered objectives magnify the specimen slightly (4x or 10X), while high-powered objectives magnify the specimen more (40X or above).
A group of organs that work together to perform a body function.
A living thing, made up of cell(s) that carries out life processes and dies. Living things can be unicellular (ex: bacteria, yeast) or multicellular (ex: rabbit, cats, ants, sunflowers).
A cell that does NOT have a nucleus or any other membrane-covered organelles. An organism that has prokaryotic cells (bacteria) is known as a prokaryote.
the cell theory
Composed of three parts:
1) All organisms are composed of one or more cells.
2) The cell is the basic unit of life in all living things.
3) All cells come from existing cells.
A group of similar cells that combine and work together to perform a specific job.
Made up of one cell. Single-celled. Uni- = one, single
