Cytoplasm Gel-like mixture Surrounded by cell membrane Contains hereditary material Endoplasmic Reticulum Moves materials around in cell Smooth type: lacks ribosomes Rough type (pictured): ribosomes embedded in surface Ribosomes Each cell contains thousands Make proteins Found on rough endoplasmic reticulum floating throughout the cell Mitochondria Produces energy through chemical reactions – breaking down fats carbohydrates Controls level of water and other materials in cell Recycles and decomposes proteins, fats, and carbohydrates Golgi Bodies Protein packaging plant Move materials within the cell Move materials out of the cell Cilia and flagella Cilia and flagella - 9 + 2 pattern of microtubules Involved in movement (cell, eggs, debris) Each cilium and flagellum has a basal body at its base. Structure of a flagellum or cilium Lysosome Digestive plant for proteins, fats, and carbohydrates Transports undigested material to cell membrane for removal Cell breaks down if lysosome explodes Vacuoles Membrane-bound sacs for storage, digestion, and waste removal Contains water solution Help plants maintain shape Chloroplast Usually found in plant cells Contains green chlorophyll Where photosynthesis takes place REVIEW List 5 structures within a cell What do golgi do? What does the mitochondria do? What is the function of the cytoplasm? What is the function of the nucleus? What does the nuclear membrane allow to happen? What is the function of the nucleolus? What is the function of the lysosome? What is the function of the endoplasmic reticulum? Why don’t animal cells contain chloroplasts? * Cytoplasm is a semi-fluid medium. Primary cell walls are made from cellulose. The secondary cell wall, which forms inside the primary wall, is formed from lignin. Its purpose is to give strength to the cell. * Basal bodies have the same microtubule arrangement as centrioles and are believed to be derived from them. The basal body initiates polymerization of the nine outer doub
