3Cell Wall (plants only) LOCATION: outside of cell membrane in plant cellsSTRUCTURE: rigid, porous; made of celluloseFUNCTION: provides support and protection for cell
4Cell Wall (plants only) The cell wall is like the walls of a factory because they both provide surrounding structure.
5CytoplasmLOCATION: fills interior of cell between cell membrane and nucleusSTRUCTURE: viscous fluidFUNCTION: provides structure and transport
6CytoplasmThe cytoplasm is like the floor of a factory because they both fill the space inside.
7Cell Membrane LOCATION: outside barrier of cell STRUCTURE: lipid bi-layerFUNCTION: allows materials into and out of cell; provides support
8Cell MembraneThe cell membrane is like the doors and windows of a factory because they both allow things in and out.
9Cytoskeleton LOCATION: throughout cell STRUCTURE: network of protein filamentsFUNCTION: provides support and transport; involved in cell movement
10CytoskeletonThe cytoskeleton is like the support beams in a factory because they both provide extra support.
11Nucleus LOCATION: towards center of cell STRUCTURE: large membrane-enclosed structure that contains the genetic materialFUNCTION: “Control Center” of cell; contains instructions for all cell functions
12NucleusThe nucleus is like the main office of a factory because they both control what is happening.
13Mitochondria LOCATION: throughout cell STRUCTURE: enclosed by two membranes, inner membrane is foldedFUNCTION: “Power Plant” of cell; convert chemical energy stored in food into useful compounds
14MitochondriaThe mitochondria are like the power lines in a factory because they both provide energy.
15Chloroplasts (plants only) LOCATION: Throughout plant cellsSTRUCTURE: surrounded by two membranes, contains chlorophyllFUNCTION: Captures energy fromSunlight, and converts it into chemicalenergy
16Chloroplasts (plants only) The chloroplasts are like solar cells in a factory because they both provide energy from sunlight.
17RibosomesLOCATION: on rough endoplasmic reticulum and free-floating in cellSTRUCTURE: small particles of RNA and proteinFUNCTION: Protein “factory” in cell; assemble proteins
18RibosomesThe ribosomes are like the machines of a factory because they both make parts.
19Endoplasmic Reticulum LOCATION: surrounding nucleusSTRUCTURE: highly folded membrane networkFUNCTION: assembles lipid, protein and other molecules
20Endoplasmic Reticulum The endoplasmic reticulum is like the assembly line of a factory because they both put parts together.
21Golgi Apparatus LOCATION: throughout cell STRUCTURE: stacks of sac-like membranesFUNCTION: modify, sort, and package materials form ER for storage or secretion
22Golgi ApparatusThe Golgi apparatus is like the shipping area of a factory because they both package and ship materials.
23Vacuoles LOCATION: throughout cell STRUCTURE: Sac-like structure FUNCTION: storage
24VacuolesThe vacuoles are like storage areas in a factory because they both store things.
25Lysosomes LOCATION: throughout cell STRUCTURE: small sac-like membranes containing digestive enzymesFUNCTION: break down waste materials in cell
26LysosomesThe lysosomes are like the clean-up crews in a factory because they both get rid of waste.
