The Cell theory states that..
1)all living things are composed of one or more cells 2)cells are the smallest units of structure & function of living things 3)New cells are produced by preexisting cells
The 2 Domains that include all organisms that are made of prokaryotic cells are-
bacteria and archaea. these organisms are multicellular and may form colonies
cytoplasm fluid part of the cell
plasma membrane : membrane surrounding the cell
ribosomes : solid,molecular organelles that make proteins
Circular DNA molecule in prokaryotes where genes are found
plasmids
cell wall
rigid structure around plasma membrane
Used for swimming (moving) through a liquid
flagellum
used to adhere to surfaces (like your teeth) fimbriae
as a cell increases in diameter, its volume increases more than its surface area. the surface area to volume ratio is reduced
since the surface is where the cell exchanges substances w/its environment, the reduction in this ratio decreases the rate of exchange. thus making cell work less efficient
