DESCRIPTION

HOW WELL DO YOU KNOW THE CELL?. NUCLEUS. Contains DNA – genetic material of the cell 2 membranes surrounding it, the envelope/membrane Controls all of the cell’s activities – including information needed to make proteins. CYTOSKELETON. Network of thin tubes in the cytosol - PowerPoint PPT Presentation

TRANSCRIPT

  • HOW WELL DO YOU KNOWTHE CELL?

  • NUCLEUSContains DNA genetic material of the cell2 membranes surrounding it, the envelope/membrane Controls all of the cells activities including information needed to make proteins

  • CYTOSKELETONNetwork of thin tubes in the cytosolMaintain a cells shape, & act as tracks that guide organelles and molecules as they move through the cell

  • PLASMA (CELL) MEMBRANECovers cell surfaceDetermines what enters or exits the cell selectively permeable

  • PROKARYOTECell that lacks a nucleus and membrane bound organellesBacteria and Archea

  • HOOKEFirst person to identify and name cells coined the term cell

  • ROUGH ENDOPLASMIC RETICULUM (ER)

    Transports materials within the cell has ribosomes attached produces phospholipids and proteins

  • GOLGI APPARATUSStacks of flattened, membranous sacsMany proteins and lipids pass from ER to here for final modifications;Like a POST OFFICE - modifies, packages and secretes various molecules

  • LYSOSOMESContain digestive enzymes to break down large molecules as well as non-functioning cell parts and cellsSmall, membrane-bound organelles formed by Golgi complex

  • LEEUWENHOEKLooked at living cells in pond water; invented first mini-microscope

  • CENTRIOLESUsed in cell divisionSeen in animal cells

  • RIBOSOMESSite of protein synthesisCan be free (in cytoplasm) or bound (attached to ER) Produced in nucleolusMade of RNA and proteins

  • SMOOTH ERTransports materials within and out of the cellFunctions in lipid synthesis ex. cholesterolNo ribosomes attached

  • EUKARYOTESType of cell with a true nucleus and membrane bound organellesPlant, protists, animal and fungi

  • MITOCHONRDRIATransfer energy from organic molecules (like glucose) to ATP (cellular energy) during the process of CELLULAR RESPIRATIONMuscle cells have lots of theseNicknamed the POWERHOUSEInner folds called cristae to increase surface area

  • PLANT CELLType of cell with a cell wall, chloroplasts and a large central vacuole

  • VIRCHOWStated cells come from the division of preexisting cells

  • CELL WALLMade of cellulose Protects, prevents excess H2O uptake, maintains shape of plant cell

  • ANIMAL CELLType of cell with lysosomes and centriolesLack a cell wallYOU ARE MADE OF THESE CELLS

  • CHLOROPLASTSUse light energy to make carbohydrates from CO2 and H2OContains chlorophyllResponsible for PHOTOSYNTHESIS

  • FLAGELLALong, tail-like projections found on the outside of cellsUsed for movement

  • CENTRAL VACUOLEStores water, enzymes, wastes, and other materialsLargest organelle in a plant cell

  • SCHLEIDENStated all plants are made of cells

  • THE CELL THEORYAll living things are composed of cellsCells are the basic units of structure and function in living thingsAll cells come from preexisting cells

  • CILIAShort, hair-like projections found on the outside of cellsUsed for movement

  • SCHWANNStated all animals are made of cells

  • CYTOPLASMJelly-like material found between the cell membrane and the nucleusContains the organelles of the cell

  • NUCLEOLUSFound inside of the nucleusMakes ribosomes
