cytology

Cytology

scientific study of cells

cell theory

basic units of structure and function in organisms; come from preexisting cells and self-reproduce

plasma membrane

semi-permeable membrane that allows certain things inside

cytoplasm

semifluid solution composed of water and inorganic and organic molecules encased by plasma membrane

organalles

tiny organs in a cell that do specialized functions that make the cell more efficient

composition of plasma membrane

phospholipids; cholesterol; trans-membrane; peripheral proteins; glycolipids

phospholipids

bilayer that’s hydrophilic on both sides but hydrophobic in the center

cholesterol

prevents plasma membrane from becoming too fluid when hot or solid when cold

types of proteins in plasma membrane

trans-membrane; peripheral proteins

trans-membrane

proteins permeate through the plasma membrane to interact with each side

What are peripheral proteins?

dont protrude through phospholipids but bind to either side of the cell

glycoproteins

cellular markers
