what is the cell membrane
|
-outer boundary of cell
-boundary b/t extracellular and intracellular compartments -controls passage of substaces in and out of cell -phospholipid bi-layer structure w/ proteins |
|
cytoplasm
|
gelatinous contents with organelles
|
|
nucleus
|
membrane bound dna
|
|
cell membrande functions
|
-membranes are impermeable (phospholipid bilayer)
-certain "pores" to permit some passage of small molecules -selectively permeable |
|
cell nucleus
|
-CEO of operations (information bank)
-contains and processes genetic information -controls cell metabolism -protein synthesis |
|
cell cytoplasm
|
-contents of the cell outside of the nucleus & inside the cell membrane
-madia for transport of intracellular substances -organelles |
|
cytosol
|
media for transportr of intracellular substances
|
|
organelles
|
-mitochondria
-endoplasmic reticulum (ER) -ribosomes -golgi apparatus -lysosome |
|
mitochondria
|
-long sausage-like tubes

|
endoplasmic reticulum
|
-transport & storage of materials in cell
-synthesis of lipids, carbohydrates &secretory proteins -system of collapsed sacs through cytoplasm |
|
ribosomes
|
-site of protein synthesis
-contains protein and RNA -found on ER or through cytoplasm |
|
GOLGI APPARATUS
|
-flattened membranc sacs
-used to package protein and other products into vesicles for export or storage in cytoplasm |
|
LYSOSOME
|
-contain digestive enzymes
-clean up debris or kill invaders |
|
TYPES OF PASSIVE PROCESSES
|
-diffusion
-osmosis |
|
DIFFUSION
|
movement of a solute in a solution from a HIGH to LOW solute concentration
|
|
OSMOSIS
|
movement of WATER from a HIGH to a LOW Water concentration
|
|
ACTIVE PROCESSES
|
-requires ATP
-move materials AGAINST concentration -Na+/K+ pump -endocytosis -exocytosis |
|
ENDOCYTOSIS
|
cell engulfs substances
|
|
EXOCYTOSIS
|
cell excretes substances
|
|
PASSIVE PROCESSE
|
DOES NOT NEED ATP
|
|
ACTIVE PROCESSES
|
REQUIRES ATP
|
|
CELL REPLICATION
|
-DNA is copied into a set of dupilcates from a single chain
-takes place in the nucleus during S phase of interphase -followed by Mitosis (division of cell) |
|
CYTOSIS
|
- bringing nutrients into the cell and ejecting waste
-endosytosis -exocytosis |
