2Cells All living things are made up of cells Cells are the building blocks of lifeOrganizationOrgan SystemsOrgansTissuesCellsTissues are made of Cells
3What are Cells? Cells have organs called Organelles Cell MembraneCytoplasm
4Cell Parts found in ALL cells Cell membraneCell boundary protecting the inside of the cell from the outsideprotective covering that encloses the entire cellAny material coming in or out must pass through the cell membraneCytoplasmGelatin like material contained inside the cell membraneMost of the work of the cell is carried out in cytoplasm
5All organelles have a function. Organelles do all the work cells needto do such as:Make ProteinTurn food into EnergyGet rid of wasteAll organelles have a function.
6Like your body's organs have functions, so do the organelles with cells. Lysosomes&PeroxysomesKidneys&Intestines
8Cells have genetic material like DNA & RNA These genes act like a computer that controlall of an organisms functions
9Eukaryotic CellsNucleusGeneticMaterialMembraneAnimal and plants, including people are made of eukaryotic cells.This means that the genetic material is surrounded by a membraneTogether, the genetic material and the membrane make up anorganelle called a Nucleus
10Genetic material located in nucleus Eukaryotic cellGenetic material located in nucleusNucleus enclosed by its own membraneOrganellesAny cell part enclosed by a membraneMost multi-cellular organisms are Euraryotic
11Prokaryotic Cells Prokaryotic Cells do not have a nucleus. FlagellaProkaryotic Cells do not have a nucleus.The genetic material floats around in the cytoplasm.Most Prokaryotes are single bacteriaFlagella are how prokaryotic & eukaryotic cells move. However, they aredifferences between the two.
12No separate compartment for genetic material Prokaryotic CellNo separate compartment for genetic materialGenetic material is in cytoplasmNo organellesMost unicellular organisms are Prokaryotic
13Do all cells look the same? Hmmm?We learned earlier that specific organs aredesigned to do a specific job.Therefore, they are made of specific types ofcells and are shape in a specific way.
14In any organism, different cells do different jobs. Muscle cells have toBe able to stretchSome bone cellsare star shapedThis bacteria hassmall hair-likeflagella to helpit moveNerve cells canbe long sothey can carryinformation around the body.
15Red blood cells are shaped like tiny bowlsPlant cells have a rigidcell wall that maintainsthe shapeCellWall
16Organelles Ribosomes: tiny structures located in the cytoplasm and ER; use information to build proteinsChloroplast:plant cell organelle that gets energy from sunlight to make sugarMitochondria:use oxygen to get energy from processing food; all eukaryotic cellsEndoplasmic reticulum(ER): system of twisting and winding membranes; manufactures parts of cell membrane
17OrganellesVesicles:formed from ER; transport processed materials to the Golgi apparatusGolgi apparatus:folded membranes that look like a stack of pancakes; finishes processing materialsVacuoles:enclosed by a membrane; sac holding water in plant cellsLysosomes:vesicles containing chemicals that break down materials taken into the animal cell
