Unit 2: Cells Chapter 7-2 Cell Organelle Notes • Two types of Eukaryotic Cells: 1. _________________________ • 2. _____________________ Organelles: “_______________________” • Specialized structures that ______________ specific ________ in the cell • Found only in __________________ cells • Many are membrane-____________ (a membrane surrounds the organelle) o ___________: watery matrix that organelles float in o ______________: everything in a cell except the nucleus (cytosol + all organelles) Organelle Cell membrane Function • _______________ the cell and decides what comes _____ and _______ Also called: • ___________________: allows nutrients in and waste products out Plasma Membrane • Made up of a _____________ bilayer Picture Factory Part Plant, Animal, or Prokaryote? Plant Animal Prokaryote Nucleus Nuclear Membrane • ___________ center of cell • Stores _______ (chromosomes) • Surrounded by the nuclear membrane (pores let materials in and out) • Nucleolus Also contains the ________________, which makes ribosomes Plant Animal Prokaryote Unit 2: Cells Chapter 7-2 Cell Organelle Notes Ribosomes • Smallest organelle Plant • NOT surrounded by a ______________ Animal • Makes ___________ according to ________ instructions Free Bound • (ER) Rough ER Smooth ER • Bound ribosomes: Attached to Rough ER __________ system for materials in Plant cell Animal • membrane • 1. __________ ER: covered in • Prokaryote ribosomes; site of _________ synthesis • 2. ________ ER: NO ribosomes; produces ____________ and lipids; • • ______________ system of the cell Collects, modifies, and packages ______________ in the cell • Vesicles Prokaryote _________ Golgi Apparatus Free ribosomes: Float free in Endoplasmic reticulum Distributes and _____________ molecules in ________________ Plant Animal Prokaryote Unit 2: Cells Chapter 7-2 Cell Organelle Notes Lysosome • ‘_________________ Disposal’ of cell Plant • Contains digestive ___________ that Animal break down waste Prokaryote Mitochondria • “__________________” of the cell Plant • Site of ________________________ Animal • Converts energy stored in ___________ into energy that the cell needs - _____ • • Found only in ______________ cells and __________ Animal Contains the green pigment Changes _______________ (solar energy) into food like _______________ (chemical energy) • Prokaryote Plant _____________________ • Sugar + Oxygen Carbon dioxide + Water + ATP Chloroplast • Sunlight + CO2 + Water Sugar + Oxygen Prokaryote Unit 2: Cells Chapter 7-2 Cell Organelle Notes Cell wall • • Rigid, protective ______________ Plant (maintains cell shape) Animal Found in ___________ and ______________ cells • Prokaryote Located ________________ of the cell membrane • Made of _______________ (carbohydrate fiber) Vacuole • • Large _______________ vacuole in Plant plant cells Animal Many ________________ vacuoles in animal cells • Storage container for water, food, enzymes, wastes, pigments, etc. • Supports cell _____________ in plants Prokaryote
