Cell wall
found in prokaryotic cells, plant and fungi cells
protects prokaryotic cell from toxins, maintains shape of cell by resisting high osmotic pressure
plasma membrane
all cells
semi-permeable phospholipid bilayer that controls what enters and exits cell, separates cell interior from external environment
cytoplasm
all cells, jelly cell-fluid
site of metabolic reactions DNA organelles and ribosomes in all (+prokaryotic) (eukaryotic) cells
Naked DNA
prokaryotes
DNA is not associated with histones, free-floating, circular in nucleoid
Ribosomes
protein synthesis, 70s prokaryotes, 80s eukaryotes
plasmid
prokaryotes
transferrable pieces of circular DNA between prokaryotic cells
Mitochondria
double-membrane bound organelles that perform aerobic respiration to create energy
Nucleus
contains histone-associated DNA organized into chromosomes
has double membrane with pores allowing certain molecules to pass (glucose, RNA, ions)
Rough ER
has 80S ribosomes attached to produce proteins sent to Golgi apparatus via vesicles
Golgi apparatus
receives proteins from ER, packages them into secretory vesicles to deliver in or out of cell
Vesicle
small sac that transports and releases substances produced within cell by fusing with cell membrane
vacuole
maintains osmotic balance of cell
can function like lysosome sometimes
