The Cell and Microscope
Living organisms are made up of things called cells.
Parts of an animal cell
Cell membrane - controls movement in and out of the cell
Cytoplasm - a jelly like substance that contains all of the parts
Mitochondria - where energy is released from nutrients through respiration
Vacuoles - contains waste from the cell
Nucleus - carries DNA and is the brain of the cell
Parts of a plant cell
Cell wall - made of a tough substance called cellulose which supports the cell
Mitochondria - where energy is released from nutrients through respiration
Cell membrane - controls movement in and out of the cell
Nucleus - carries DNA and is the brain of the cell
Large vacuole - contains a liquid called cell sap that keeps the cell firm and holds nutrients
Cytoplasm - a jelly like substance that contains all of the parts
Chloroplast - this is where the plant makes food using a process called photosynthesis
Light Microscope
Parts of a microscope
Uses a series of lenses to magnify an object.
Objective lens - each objective lens has a different magnification
Nose piece - can move different objective lenses into place.
Fine focus knob - used for delicate focusing on high power
Stage - part where you place the slide
Course focus knob - used to see an object on a low magnification
Clip - to hold the slide in place on the stage
Eyepiece - the lens nearest to your eye and magnifies objects 10x
Light - to shine light up through the object to see
Eyepiece magnification x objective lens magnification = total magnification
