| organelle | subcellular structure |
| prokaryote | cells w/ no nucleus |
| eukaryote | cells with nucleus |
| cytosol | semi-fluid medium found in cytoplasm |
| cytoplasm | entire region between nucleus and membrane enclosing cell |
| nuclear envelope | double membrane w/ pres that regulate the mov't of large molecules |
| chromatin | DNA substance which makes chromosomes |
| nucleolus | makes ribosomal components that pass through nuclear pores |
| free ribosomes | produces proteins to be used w/in the cytosol |
| Bound ribosomes | attach to ER, make proteins to be used w/in membranes |
| endomembrane system | nuclear envelope, ER, Golgi apparatus, lysosomes, vacuoles and plasma membrane are part of this system |
| Endoplasmic Reticulum | continuous w/ nuclear envelope. Has components called cisternae |
| smooth ER | involved w/ detoxification of drugs / poisons; lipid synthesis |
| rough ER | produces proteins intended for secretion |
| Golgi apparatus | flattened membranous sacs. |
| lysosomes | digest macromolecules, and maintain acidic pH for enzymes. |
| tonoplast | membrane which surrounds central vacuole in mature plant cells |
| peroxisome | single membraned- breaks H2O2 into water |
| mitochondria | site of cellular respiration / production of ATP |
| cristae | the folds of the inner membrane of mitochondria |
| plastids | organelles which include chromoplasts and chloroplasts |
| cytoskeleton | network of fibers that functions in support of cells |
| microtubules | hollow rods, provide framework of cell |
