responsible for producing proteins and is located in the cytoplasm and er
Term
golgi apparatus
Definition
modifies, supports and delivers proteins in the cell
Term
vacuoles
Definition
stores necessary material for the cell (larger in animals then plants)
Term
chloroplast
Definition
carries out photosynthesis in plant cells. they have there own dna and ribosomes
Term
cell wall
Definition
in plant cells supports and shapes the cell
Term
chromatography
Definition
seperates mixtures. components based on their soulubility ( the most soluble are at the top, the lostest on the bottom)

centrosomes
Definition
produces microtubles and contains centrioles,
Term
centrioles
Definition
important during cell division
Term
lysosomes
Definition
protects the cell and breaks down cell pparts

cell,tissue,organ,organ system,organism
Term
cell (plassma) membrane
Definition
controls the material that goes into and out of the cell also seperates the cell from the living enviornment
Term
phospholipids
Definition
make up thr cell membrane, the heade is hydrophilic and the tail is hydrophobic,
Term
phospholipid biolayer
Definition
contain chlorestroyl- strengthens cell membrane and the proteins that that transport materials and sends signals across the membrand and the carbs- used as a identification marker.
Term
pinocytosis
Definition
cell drinking, vesicels formed at cell surface take in large dissolved molecules,
Term
phagocytosis
Definition
engulfment of large chunks of food or even cells
Term
receptor
Definition
protein that detects a signal molecule and preforms an action in responce
Term
intracellular receptors
Definition
protein in the cell that binds to the molecules that cross the cell membrane
Term
membrane receptor
Definition
proteins int he cell membrane that bind to molecules
Term
nutriton
Definition
ingestion-taking in food
digestion-breaking down food
egestion-eliminating the food

chemical activities when large molecules and built from smaller molecules
Term
regulation
Definition
control of the various activities of a organism
Term
metabolism
Definition
total of all life activities required to substian life
Term
homeostasis
Definition
when life functions are carried out and need a stable internal enviornment
