| 5008367186 | Plasma Membrane | Double membrane, outer rim of cell, Lets only select things in and out of cell | 0 | |
| 5008367187 | Cell Wall | Only in plants-CELLULOSE, surrounds plasma membrane, protects and gives cells shape | 1 | |
| 5008367188 | Chromatin | Tangles of long strands of DNA, nucleus, packed into chromosomes when cell reproduces | 2 | |
| 5008367189 | Nucleolus | A semi-large region, nucleus, produces ribosomes that are involved in protein synthesis | 3 | |
| 5008367190 | Ribosomes | Tiny cell particles (not membrane bound), cytoplasm, synthesis proteins | 4 | |
| 5008367191 | Cytoplasm | Clear fluid, lies outside nucleus/ surrounds organelles, site of protein assembly | 5 | |
| 5008367192 | Endoplasmic reticulum | Folded membrane (one rough[ribomsomes] one smooth), cytoplasm, network of interconnected systems | 6 | |
| 5008367193 | Golgi Apparatus | Closely stacked, cytoplasm, delivers proteins to plasma membrane | 7 | |
| 5008367194 | Vacuole | Sac of fluid, cytoplasm, stores food-enzymes and other materials needed by cell | 8 | |
| 5008367195 | lysosomes | surrounded by membrane, cytoplasm, digests excess or worn out cell parts | 9 | |
| 5008367196 | mitochondria | highly folded inner membrane, cytoplasm, food molecules are broken down to create energy | 10 | |
| 5008367197 | chloroplasts | disc shaped, plant cells, transform light energy to CE | 11 | |
| 5008367198 | Chlorophyll | green pigment, thylakoid membrane, traps energy from sunlight | 12 | |
| 5008367199 | plastids | different color pigments, plant cells, storage | 13 | |
| 5008367200 | cytoskeleton | thin fibrous elements, throughout the cell, supports cell and organelles | 14 | |
| 5008367201 | microtubules | thin,hollow cylinders-cytoskeleton, provides protein to to cytoskeleton | 15 | |
| 5008367202 | cilia | hair like, plasma membrane, moves fluid over cell surface | 16 | |
| 5008367203 | flagella | "whip like" and long, one or two per cell | 17 | |
| 5008367204 | intermediate filaments | fibrous proteins that are (keratin) that are coiled into thicker cables and filaments | 18 | |
| 5008376326 | intercellular junctions | plants-plasmodesmata -channels between cells through adjacent cell walls -allows communication between cells -allows viruses to travel rapidly between cells | 19 | |
| 5008376327 | tight junctions | -very tight fusion of the membranes of adjacent cells -seals off areas between the cells -prevents movement of materials around cells | 20 | |
| 5008376328 | demosomes | -bundles of filaments which anchor junctions between cells -does not close off the area between adjacent cells -coordination of movement between groups | 21 | |
| 5008376329 | gap junctions | -opens channels between cells, similar to plasmodesmata -allows "communication" between cells | 22 | |
| 5009225283 | middle lamella | thin layer rich in pectin; glues plant cells together | 23 |
