What 3 parts to do ALL cells have in common?MembraneCytoplasmDNA1Cell MembraneWhen you think about a membrane, imagine it is like a big plastic bag with some tiny holes. That bag holds all of the cell pieces and fluids inside the cell and keeps any nasty things outside the cell. The holes are there to let some things move in and out of the cell. Selectively permeable- only allowing some things to pass in and out

2Cell MembraneIs not one solid piece. Everything in life is made of smaller pieces and a membrane is no different. Compounds called proteins and phospholipids make up most of the cell membrane. The phospholipids make the basic bag. The proteins are found around the holes and help move molecules in and out of the cell.

3CytoplasmAs you travel through the cell membrane and enter the cell, you will find yourself floating in a kind of jelly, this is the cytoplasm.Cytoplasm helps to hold the cell's organelles or small organs in place.

4CytoplasmGives the cell structure. Think of a balloon. An empty balloon does not have much structure. However, if we fill it with something, like water, it begins to take shape.Cytoplasm also helps the cell move proteins, chromosomes and other materials, including the cells organelles, around the cell.

5DNADNA is like the instruction manual of a cell.It comprises of a long string of code which tells the cell what type of cell it has to be and what functions it must perform.

The Cell and the City

9Eukaryotic CellAre what you think of when you think of a classic "cell." They are cells with an organized nucleus.All living organisms on Earth are divided in pieces called cells. There are smaller pieces to cells that include proteins and organelles.

10NucleusActs like the brain of the cell. It helps control eating, movement, and reproduction. If it happens in a cell, chances are the nucleus knows about it. The nucleus is not always in the center of the cell. It will be a big dark spot somewhere in the middle of all of the cytoplasm.City Hall

11DNALong molecule containing hereditary information that directs the cells functions and the organisms development.City Documents

12Endoplasmic ReticulumThe ER is the site of protein and lipid production. Factory

13RibosomesAre the protein builders or the protein synthesizers of the cell. Cells need to make proteins. Those proteins might be used as enzymes (increase rate of chemical reactions) or as support for other cell functions. Complexes that use DNA copies to build proteinsFactory Workers

14Golgi ComplexPackages and modifies proteins, then send them off to their destinations.Works closely with the Rough ERPost office

15Cell MembraneActs as a semi-permeable barrier that lets certain things pass into and our of the cell.Protection and support for the cell.City Limits

16MitochondrionKnown as the powerhouses of the cell.They are organelles that act like a digestive system that takes in nutrients, breaks them down, and creates energy for the cell.Uses oxygen and food molecules to generate useful energy for the cell.Power Plant

17ChloroplastsUses sunlight, carbon dioxide, and water to produce glucose and oxygen through the process of photosynthesis. Food producers of the plant cell.Every green plant you see is working to convert the energy of the sun into sugars. Restaurant

18VacuolesStores water, salts, and nutrientsStorage bubbles found in cells. They are found in both animal and plant cells but are much larger in plant cells.Reservoir

19LysosomesDigests or breaks down waste, old cell parts, viruses and bacteria.Recycling center

20CiliaHair-like structures wave to move a cell around, or to move something around the cell. Can keep dust, smog, and potentially harmful microorganisms out

21CentriolesEvery animal cell has two small organelles called centrioles. They are there to help the cell when it comes time to divide. You will usually find them near the nucleus but they cannot be seen when the cell is not dividing. The centrioles are made of Microtubules.

22Microtubules/MicrofilamentsHelp define cell structure and movementAre thick, strong spirals of thousands of subunits. Those subunits are made of the protein called tubulin. And yes, they got their name because they look like a tube.

23NucleolusA small round body of protein in a cell nucleus.The main function of the nucleolus is to produce and assemble the ribosome components.

24CytoplasmThe fluid that fills a cell.Mix of molecules, proteins and small cell parts.Chemical reactions occur here.

25Cell WallCell walls are made of specialized sugars called cellulose. Paper is made of cellulose. Cell walls also help a plant keep its shape. While they do protect the cells, cell walls and cellulose also allow plants to grow to great heights.It's like taking a water balloon and putting it in a cardboard box. The balloon is protected from the outside world.
