Unit 2-Cells
| Organelle | Function | Animal, Plant, or both? |
|---|---|---|
| nucleus | command center, contains genetic material | both |
| nucleolus | ribosomes produced | both |
| nuclear envelope | double membrane between nucleus and cytoplasm | both |
| nuclear pore | opening in nuclear envelope, regulates passage | both |
| ribosome | ribosomal RNA and protein that are sites of PROTEIN SYNTHESIS. free ribosomes create proteins for inside the cell | both |
| plasma membrane | lipid bilayer in which proteins are embedded. controls the movement of substances in/out the cell | both |
| cytoplasm | semi-fluid matrix | both |
| mitochondria | site of cellular respiration, ATP energy produced. double membrane | both |
| smooth er | aids in synthesis of lipids and detoxification | both |
| rough er | covered with ribosomes. carry out protein synthesis. | both |
| golgi complex | corret folding and chemical modification of newly synthesized proteins. packages proteins into vesicles. lysosomes are formed here. | both |
| secretory vesicle | vesicle that will fuse with the plasma membrane, releasing materials to be secreted from the cell. | both |
| lysosome | vesicles that contain hydrolytic enzymes. digest and recycle cell's organic materials and apoptosis. formed at golgi body. | animal |
| small vacuole | storage. release of macromolecules when needed. | animal |
| cilia | movement, steering | animal |
| flagellum | movement, power | animal |
| peroxisome | vesicle that contains enzymes, carries out reactions such as detoxifying harmful substances | animal |
| centriole | complex assembly of microtubules. involved in cell division | animal |
| cytoskeleton | supports organelles and cell shape, plays a role in cell motion | animal |
| cell wall | provides support. tough cellulose fibers | plant |
| large central vacuole | storage for water, sugars, ions, and pigments. aids in retention of water for turgor pressure | plant |
| chloroplast | site of photosynthesis | plant |
| plasmodesmata | openings in cell wall that function in cell to cell communication | plant |
| matrix | space in the inner membrane of the mitochondria. contains ribosomes and genetic material | both |
| cristae | folds in the mitochondria that increase surface area | both |
| stroma | fluid in the chloroplast | plant |
| lumen | space inside the thylakoid disk | plant |
| thylakoid disk | contains chlorophyll | plant |
| granum | stack of thylakoid disks | plant |
