CELL THEORY
Cells are the basic units of structure &
function of all living things
All cells carry on life functions (processes)
Cells arise only from preexisting cells
Organisms can be unicellular (Ex. bacteria)
OR multicellular (Ex. plants, animals)

Centrioles are found near the nucleus of
animal cells (but NOT found in plant cells)
http://www.eccentrix.com/members/chempics/Slike/cell/centrosome.jpg
Centrioles consist of microtubules

Cilia located along the respiratory tract

Flagella are also made up of microtubules
