| A | B |
|---|
| Plasma membrane | Semifluid cell boundary; controls passage of materials in and out of cell |
| Nucleus | control center of cell; nuclear envelope with pores formed of 2 membranes |
| Cytoskeleton | network of proteins of microtubules |
| Cytoskeleton | Provides shape, internal organization, and movement |
| Plasma membrane | Lipid layers embedded with proteins |
| Lysosome | Formed by budding from Golgi apparatus |
| Lysosome | fuses with vesicles |
| Centrioles | Tubular structures formed of microtubles |
| Cell Wall | Made of cellulose fibers embedded in polysaccharides |
| Mitochondrion | double membrane-inner much folded |
| Mitochondrion | Where reactions of cellular respiration occur |
| Endoplasmic Reticulum | Seperates the cytosol |
| Golgi apparatus | flattened sacs that sort macromolecules in vesicles for secretion |
| Rough ER | studded with ribosomes |
| Cytosol | semi-fluid material surrounded by organelles |
| Cytosol | contains enzymes that catalyze cellular reactions |
| Chloroplast | double membrane; where photo occurs |
| Chloroplast | 3rd membrane system forms thylakoids |
| Vacuole | Large vesicle; stores nutrients and waste products |
| Cytoplasm | In plasma membrane but outside nucleus |
| Ribsomes | small bodies where proteins are synthesized |
| Vesicle | membrane enclosed sac where substances are stored or transported |
| Nucleoid | Area in prok consisting of DNA |
| Nucleolous | Structure in nucleous associated with production of ribosomes |
| Lysosome, Centrioles | only in animal cell |
| Cell Wall, Chloroplasts, Vacuole | only in plant cell |
