508600099 | Prokaryotic Cell | a type of cell which has its DNA concentrated at the nucleoid, which is not surrounded by a membrane | |
508600100 | Nucleoid | the area not enclosed by a membrane where the DNA is concentrated, in a prokaryotic cell | |
508600101 | Eukaryotic Cell | a type of cell which has a true nucleus, and many organelles | |
508600102 | Cytoplasm | the entire space between the nucleus and the plasma membrane | |
508600103 | Plasma Membrane | the selective barrier which allows the sufficient passage of oxygen, nutrients, and wastes to service the entire volume of the cell at the boundary of the cell | |
508600104 | Flagellum | locomotion organelle present in some animal cells; composed of membrane-enclosed microtubules | |
508600105 | Centrosome | region where the cell's microtubules are initiated; in an animal cell, contains a pair of centrioles | |

508600110 | Lysosome | digestive organelle where macromolecules are hydrolyzed | |
508600111 | Golgi Apparatus | organelle active in synthesis, modification, sorting, and secretion of cell products | |
508600112 | Ribosomes | nonmembranous organelles that make proteins, free in cytoplasm or bound to rough ER nuclear envelope | |
508600113 | Chromatin | material consisting of DNA and proteins; visible as individual chromosomes in a dividing cell | |
508600114 | Nucleolus | nonmembranous organelle involved in production of ribosomes; a nucleus has one or more nucleoli | |
508600115 | Nuclear Envelope | double membrane enclosing the nucleus; perforated by pores, contiguous with ER | |
508600116 | Cell Wall | outer layer that maintains cell's shape and protects cell from mechanical damage; made of cellulose, other polysaccharides, and protein | |
508600117 | Plasmodesmata | channels through the cell walls that connect the cytoplasm of adjacent cells | |
508600118 | Chloroplast | photosynthetic organelle, converts energy of sunlight to chemical energy stored in sugar molecules | |
508600119 | Central Vacuole | prominent organelle in older plant cells, functions include storage, breakdown of waste products, hydrolysis of macromolecules; enlargement of vacuole is a major mechanism of plant growth | |
508600120 | Endoplasmic Reticulum | network of membranous sacs and tubes; active in membrane synthesis and other synthetic and metabolic processes; has rough(ribosome-studded) and smooth regions | |

508600126 | Contractile Vacuoles | they pump out excess water due to osmosis | |
508600127 | Cristae | infoldings of the inner membrane in mitochondria | |
508600128 | Mitochondrial Matrix | the space in between the cristae | |
508600129 | Thylakoids | membranous system in the form of interconnected sacs in chloroplast | |
508600130 | Granum/ Grana | each stack in the choloroplast | |

508600132 | Centrioles | composed of nine sets of triplet microtubules arranged in a ring | |
508600133 | Integral Proteins | proteins which penetrate the hydrophobic core of the lipid bilayer | |
508600134 | Peripheral Proteins | proteins that are not embedded in the lipid bilayer, but are loosely bound to the surface | |
508600135 | Glycoproteins | carbohydrates covalently bonded to protein | |
508600136 | Glycolipid | carbohydrates covalently bonded to lipid |
