| 5266652710 | nucleus | contains DNA, surrounded by selectively permeable nuclear membrane (envelope) | 0 | |
| 5266652711 | nuclear membrane | contains pores to allow for transport of molecules such as RNA | 1 | |
| 5266652712 | nucleolus | synthesis of ribosomes | 2 | |
| 5266652713 | ribosomes | synthesis of proteins | 3 | |
| 5266652714 | Smooth ER | 3 functions: assists in synthesis of lipids, connects rough ER to Golgi, Carries out various detoxification processes | 4 | |
| 5266652715 | Rough ER | site of protein synthesis (attached ribosomes) | 5 | |
| 5266652716 | Golgi Body/Apparatus | surrounded by vesicles, packages substances produced in rough ER: secrete them to other parts of cell for export | 6 | |
| 5266652717 | lysosomes | sacs of hydrolytic (digestive) enzymes—site of intracellular digestion, assists in apoptosis (programmed destruction of cells) | 7 | |
| 5266652718 | cytoplasm | thick liquid between membrane, holds organelles, most cellular activites occur here, ex: glycolysis | 8 | |
| 5266652719 | Vacuoles | structures for storage | 9 | |
| 5266652720 | Vescicles | transport things | 10 | |
| 5266652721 | mitochondria | site of cellular respiration—have an outder double membrane, inner series of membranes called cristae. contain own DNA | 11 | |
| 5266652722 | chloroplasts | site of photosynthesis, have inner membrane that forms series of structures called grana (stack of thylakoids), found in the stroma. Contain own DNA | 12 | |
| 5266652723 | cytoskeleton | complex network of protein filaments—gives cell its shape, enables it to move, anchors organelles to plasma membrane. includes microtubules and microfilaments. | 13 | |
| 5266652726 | tubulin (microtubule) | hollow tubes made of protein tubulin that make up cilia, flagella, and spindle fibers | 14 | |
| 5266652727 | cell membrane | protects/encloses cell—allows some substances to travel out of/into cell. isolates cell's contents, regulates movement of substances into/out of cell, communicates with other cells—made of fluid mosaic phopholipid bilayer | 15 | |
| 5266652728 | cell wall | made of cellulose, found in plants, algae. cell walls of fungi made of chitin. primary cell wall-immediately outside plasma membrane. secondary cell wall—second series outside of primary layer. during cytokinesis, middle lamella or cell plate forms. | 16 | |
| 5266652729 | Differences between plant/animal cells | a. plants have cell wall b. plants have chloroplasts c. animals have centrioles | 17 | |
| 5266652730 | 3 functions of cell membrane | i.Isolate cell's contents from external environment ii.Regulate mvmt of substances into and out of cell iii.Communicate with other cells | 18 | |
| 5266652732 | Surface area/volume ratio | The surface area: volume ratio decreases as cells grow bigger. As the diameter of sphere grows bigger, the surface area grows smaller. This allows less room for substances to diffuse into/out of cell and makes the diffusion distance (from center of cell to membrane) bigger. | 19 |
