Cell Size From Smallest to l a rgest + Prokaryotic Cells
Kind of CellSize (approximate) Bacteria(E. coli) 1 um Red Blood Cell 8 um Elodea epidermal cell 65 um Amoeba 700 um Hen's egg 50,000 um
Smallest Cells Mycoplasmas bacteria 0.1 -1.0 µm
Largest Cells *Ostrich Egg Chicken Egg
Metrics 1 cm = 0.01 m (10 -2 )m centimeter 1 mm = 0.001 m (10 -3 )m millimeter 1 µm = 0.000 001 m (10 -6 )m micrometer 1 nm = 0.000 000 001 m (10 -9 )m nanometer 1 Å = 0.000 000 0001 m (10 -10 ) Angstrom
Longest Cells Muscle and Nerve Cells
Form and Function Nerve Long to send impulses
Form and Function Muscle Move bones
Form and Function Blood Cells Smooth, travel through blood vessels
Form and Function Skin Cell Flat top for protection Cube for cushion
As cells get larger, the surface area to volume ratio ______________________ (increases/decreases). decreases
