Cellular Organelles
Function of Cell Parts
| Question | Answer |
|---|---|
| The cell part that controls what enters and leaves the cell. | Cell Membrane (aka plasma membrane) |
| The control center of the cell. | Nucleus |
| synthesizes ribosome parts | Nucleolus |
| synthesizes proteins by bonding together amino acids | Ribosomes |
| Releases energy in organic molecules and then uses that energy to produce ATP. | Mitochondria |
| Transforms the sun's energy into the chemical energy of organic molecules (specifically glucose). | Chloroplast |
| Finishes the synthesis of secretory proteins and then transports them via vesicles to the Golgi body | Rough endoplasmic reticulum |
| synthesizes lipids and detoxifies alcohol | Smooth endoplasmic reticulum |
| Digests wastes. | Lysosome |
| Help move chromosomes during cell division. | Centrioles |
| Gives shape and support to plant and bacterial cells. | Cell wall |
| A gel like substance that includes everything from the outside of the nucleus to the cell membrane. | Cytoplasm |
| Stores water and chemicals. These are very large in plant cells. | Vacuole |
| Cells without membrane bound organelles. | Prokaryotes |
| Cells with membrane bound organelles. | Eukaryotes |
| Finishes, sorts and ships chemcials to locations through the cell or out of the cell. | Golgi body |
| Surrounds the nucleus and controls what enters and leaves it | nuclear envelope |
| Breaks down peroxide which is a waste product of many chemical reactions that occur in the cell | peroxisome |
| central vacuole | stores water in plant cells; helps maintain turgor pressure |
| network of protein fibers that functions in structural support and motility | cytoskeleton |
| What three cell parts do prokaryotic and eukaryotic cells both contain? | plasma membrane, chromosomes, ribosomes |
| What two cell parts are found in animal cells that are not in found in plant cells? | lysosomes, centrioles |
| What three cell parts are found in plant cells that are not found in animal cells? | cell wall, central vacuole, chloroplasts |
| The presence of organelles in eukaryotic cells enables them to be larger than prokaryotic cells because | the chemicals needed are contained within the small space of each organelle and have a high chance of reacting |
| the gel-like material extending from the cell membrane to the nuclear envelope is called the | cytoplasm |
| propels a cell by an undulating whip-like motion | flagella |
| strong fibers located just outside the plasma membrane that support and protect the plasma membrane | extracellular matrix |
| moves materials through the cell along the cytoskeleton using motor proteins | transport vesicles |
