Cell Parts and Functions Identify by Picture Cell Membrane • Regulates what enters and leaves the cell. Nucleolus • Structure in the nucleus which makes ribosomes for protein synthesis Nucleus • Controls activities of the cell and contains genetic material Mitochondria • Provides cell with energy by using sugar (glucose) as a fuel source. Rough Endoplasmic Reticulum • A system of channels that transport proteins through the cell Smooth Endoplasmic Reticulum • A system of channels that manufacture carbohydrates and lipids and transports them through the cell Golgi Body (Apparatus) • Collects, modifies, and packages chemicals made at one location in a cell and secretes finished products to be used at another location in the cell • Dots? Ribosomes • Manufacture proteins in the cell • Yellow area? Cytoplasm • Gel-like fluid inside the cell that all organelles are suspended in # 5? # 6? Vacuoles • Store materials such as water, salts, carbohydrates, and waste materials. They may occupy a large space within plant cells. Green area? Cell Wall • Supports, strengthens, and protects the cell. Not found in animal cells. Chloroplasts • Photosynthetic organelles found in plant cells Lysosome • Contains chemicals and enzymes needed for digesting certain materials in the cell.
