Lumberton High Sci Vis II V Epithelial Cell

 Bodies of all organisms are made of cells.  Without cells there is no life.

 Double layer of lipids with proteins for cell activity.  The proteins are receptors, pores, and enzymes.  Lipid layer (phospholipids) is a water-fearing molecule.  Responsible for controlled entry/exit of substances Drawing of a cell membrane

 Brain of the cell.  Controls all parts of the cell and its functions.  A membrane-bound organelle. (Dbl mbrn)  Communicates using nuclear pores.  DNA is found here.  Prominent structure is the nucleolus.  Nucleolus produces ribosomes & RNA The cell nucleus

 Provide cell with energy through respiration.  Double membrane-bound organelles.  Outer mmbrn smooth  Inner mmbrn twisted with cristae (folds)  On the cristae, sugar combines with O2 to form ATP (energy source). Nuclear Power Plant

 Single membrane-bound structure.  Packaging and shipping of a cell.  Packages are fluid-filled & called vesicles.  Vesicles transport large molecules in cells. Golgi bodies

 Site of protein synthesis.  Read code found in RNA.  Assemble proteins cell’s need for growth and different functions. Ribosome pic

 Connects outer nuclear membrane with the cell membrane.  Function as channels within the cell.  Two types: Smooth and Rough.  Smooth are for fat and membrane protein production.  Rough have ribosomes on its surface and synthesize other proteins Endoplasmic reticulum

 Membrane organelles that store substances.  Vacuoles move substances in and/or out of the cell.  Movement in or out of the cell is down by fusing with the cell membrane. Vacuole

 Have 2 or more organelles than the animal cell:  Cell Wall  Chloroplast  The vacuole is larger in plant cells

 Used to support the plant.  Made of fiber called cellulose.  Cellulose is not digested by living organisms (COLON CLEANSE!)  Connected to cell membrane Plant Cell Wall

 Site for photosynthesis  Photosynthesis is when sunlight, H2O, and CO2 are use to make glucose and oxygen  Chlorophyll is a green pigment found here.  Chlorophyll collects the sun’s energy. Chloroplast
