| A | B |
| mitochondria | chemical reactions that transfer energy from organic compounds into ATP - contain DNA |
| mitochondria have ______ | two membranes |
| mitochondria have a smooth ____________ | outer membrane - separates it from cytoplasm |
| mitochondria have an inner membrane that ____________ | has long, inward folds - cristae - increase surface area - more space for reactions |
| most numerous amounts of mitochondria are in the _______ | muscles and liver |
| lysosomes | found in most animal and fungal cells - not commonly in plants |
| hydrolytic enzymes | breakdown of food, bacteria, and damaged cell parts |
| selectivity destroy _________ | tissues and form fingers |
| golgi apparatus | processing, packaging and secreting flattened sacs piled on top of each other - modifies protein for export |
| receive protein | forms a membrane pouch (vesicle) |
| cytoskeleton | protein strands in cytosol - maintain shape and |
| microtubulels | composed of protein and gives support |
| cell division of microtubulels? | form spindle fibers - assist in movement of chromosomes |
| cilia and flagella | two kinds of structures extending out of surface of cell - function - movement |
| cilia | short, hairlike extensions (ex. paramecium) |
| flagella | whiplike, longer than cilia - unicellular |
| both the cilia and flagella have ____________- | similar internal structures - 9 pairs of microtubules around central pair |
| plant cells consist of __________ | vacuoles, cell wall, plastids |
| vacuoles | fluid filled cavity or sac - store enzymes and waste products - some may be toxic |
| cell wall of plant cell | surrounds membrane and protects and supports - made of cellulose |
| plastids | double membrane and DNA - store food and pigments - converts solar energy into chemical energy |
| chloroplasts | green pigment chlorophyll - thylakoids - a flattened, membraeous sac |
