CellOrganelles

Nucleus(Both Plant& Animal)** -Controls cell activities -Breaks down sugar molecules into energy -Second largest organelle with unique genetic structure -Double-layered outer membrane with inner folds called cristae -Energy-producing chemical reactions take place on cristae -Controls level of water and other materials in a cell -Recycles and decomposes proteins, fats, and carbohydrates, and forms urea -Powerhouse of a cell -Contain green chlorophyll where photosynthesis takes place -Uses energy from the sun to make food for the plant -Digestive 'plant' for proteins, lipids, and carbohydrates -Transports undigested material to cell membrane for removal -The cell breaks down if the lysosome explodes -Digests old cell parts -Breaks down larger food molecules into smaller molecules -Membrane-bound sacs for storage, digestion, and waste removal -Contains water solution -Contractile vacuoles for water removal (in unicellular organisms) -Each cell contains thousands -Minature 'protein factories' -Composes 25% of cell's mass -Stationary type: embedded in rough endoplasmic reticulum -Mobile Type: injects proteins directly into cytoplasm -Tubular network fused to nuclear membrane -Goes through cytoplasm onto cell membrane -Stores, separates, and serves as cell's transport system -Smooth type: lacks ribosomes -Rough type: ribosomes embedded in surface The book says at page 177 that -lipids, proteins, and other materials are assembled here and transported -Protein 'packaging plant' -A membrane structure found near nucleus -Composed of numerous layers forming a sac -Paired cylindrical organelles near nucleus -Composed of nine tubes, each with three tubules -Involved in cellular division -Lie at right angles to each other The book says at page 179 that -they are filled with enzymes -breaks down lipids, proteins, and carbohydrates
