Electron Microscope Using beams of electrons to produce a magnified image.
Magnification The condition of things appearing larger then they are, using convex lenses (center is thicker than the edges)
Resolution The ability to see to details more clearly, the higher the resolution the sharper the image.
Multicellular Made of many cells
Unicellular Made of only ONE cell

Water in cells A. Water B. Water helps cells keep C. Water helps cells maintain their D. Water helps cells carry substances in and out of
Passive Transport When materials go in and out of the cell WITHOUT using energy.
Diffusion The movement of molecules from an area of high concentration to an area of low concentration.
Osmosis The movement of WATER molecules across a selectively permeable membrane.
Selectively permeable means some substances can cross the membrane while others cannot.
Active transport When materials go in and out of the cell using energy.
Endocytosis The cell changes shape and engulfs the particle.
Exocytosis The reverse process, which allows large particles to exit the cell.
Characteristics of Living Things RULE #1 Must be made of Cells RULE # 2 Must be organized RULE # 3 Types of organisms RULE # 4 Homeostasis RULE # 5 Growth and Development RULE # 6 Reproduction
