| Question | Answer |
|---|---|
| cytoskeleton | meshlike network that spans the cell and gives the cell shape and holds the organelles in place |
| centrioles | cytoskeleton component that anchors the microtubules in place |
| vacuole | organelle that stores water, waste, and food; huge in plant cells and small in animal cells |
| cell wall | found only in plant cells; urrounds the cell membrance and is made of cellulose which makes the plant wall rigid |
| phospholipid bilayer | composes the membrances that surround all the cell organelles in the eukaryotic cell; made of 2 layers of phospholipids; the head (glycerol) is polar and the tails (fatty acids) are nonpolar; so polar items can not get through the membrances |
| lysosome | contains the cell's digestive enzymes and breaks down proteins, lipids, and fats; also breaks down old organelles and even the cell itself |
| microtubules | cytoskeleton component that moves chromosomes across the cell during cell division |
| flagella | cytoskeleton component that extends from the back of the cell and acts in locomotion; moves in a whiplike motion |
| cilia | cytoskeleton component that extends from the cell like little hairs and acts in locomotion; moves the cell in a curcular motion |
| 3 differences in plant cells and animal cells | plants have a CELL WALL plants have a HUGE VACUOLE plants have CHLOROPPLASTS |
| nuclear membrance | surrounds the necleus and regulates what gets into and out of the necleus |
| cell membrane | phospholipid bilayer that regulates what gets in and out of the cell; it is SELECTIVELY PERMEABLE! Protein channels in the layer allow polar items to move in and out |
| smooth ER | the ER without ribosomes; makes FATS |
| endoplamic reticulum | system of membranes that extend through the cell and act as a transportation system for proteins to travel on |
| vesicles | membrane enclosed sacs that carry proteins safely around the cell to the different organelles |
| mitochondria | converts glucose into ATP- the energy molecule of the cell. Found in plants and animals |
| chromosome | DNA wrapped around proteins in a rod shaped structures so DNA can fit in the necleus |
| rough ER | the ER that has robisomes attached to it |
| Golgi Apparatus | stacked membrances that package and sort proteins from the rough ER. Has enzymes that label the proteins and tell them were to go next |
| chloroplasts | take water and sunlight and produce glucose (food); found only in plant cells |
| nucleus | directs all the cells activities and stores the cells DNA. Contains the nucleolus- in the center of nucleus and makes ribosomes |
| peroxisomes | contains enzymes that convert fats to carbohydrates and convert H2O2- hydrogen peroxide to water |
| prokaryotic | cells with no nucleus and no membrane bound organelles; very small and simple cells; bacteria |
| eukaryotic | cells with a true nucleus and membrane bound organelles; has linear DNA strands; it's larger and more complex PROTISTS, FUNGI, PLANTS, ANIMALS |
