Cell organelles
Nucleus(Both Plant& Animal)

-Controls cell activities
Mitochondria(Both Plant& Animal)
-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
Chloroplast(Only Plant)
-Contain green chlorophyll where photosynthesis takes place
-Uses energy from the sun to make food for the plant
Lysosome(Common in Animal)
-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
Vacuole(Both Plant& Animal)
-Membrane-bound sacs for storage, digestion, and waste removal
-Contains water solution
-Contractile vacuoles for water removal (in unicellular organisms)
Ribosome(Both Plant& Animal)
-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
Endoplasmic Reticulum(Both Plant & Animal)
-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
Golgi Apparatus
-Protein 'packaging plant'
-A membrane structure found near nucleus
-Composed of numerous layers forming a sac
Centrioles
-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
