Organelle Flip Book • • • • • • • • Organelles Cell Membrane Cytoplasm Cell Wall Nucleus Chloroplast Mitocondria Ribosome • Endoplasmic Reticulum • Golgi Body • Nucleolus • Lysosome • Vacuole • Cytoskeleton • Tissue • Organ The Parts of a Cell Organelles • Little cell structures that have specific functions • Found in eukaryotes Cell Membrane • Cell’s security system • Surrounds and protects cell • Controls what enters and exits the cell Cytoplasm • Gel-like substance inside the cell • Where cell processes (chemical reactions) occur • It is 80% water Cell Wall • Tough structure that surrounds and protects plant cells • Gives cells shape • Made of cellulose Nucleus • Control center of the cell • Contains directions for the entire cell • DNA is found here • Surrounded by a nuclear membrane Chloroplast • • • • Green organelle In plant cells Photosynthesis Captures energy from the sun to make glucose (plant food) Mitochondria • Cell’s energy dam • Stores and releases cell’s energy • “Powerhouse” Ribosome • Protein factories • Make proteins • Some float freely in the cytoplasm, others are attached to the E.R. Endoplasmic Reticulum • Cell’s railroad track • Moves materials around in cell • Smooth - no ribosomes • Rough – has ribosomes Golgi Body • Cell’s post office • Sorts and packages proteins into vesicles • Vesicles deliver substances in the cell and also attach to the cell membrane to release materials to the outside Nucleolus • Manufactures the proteins that make up the ribosomes • Found in the nucleus Lysosome • Cell’s landfill • Digests food molecules, cell wastes, and worn out cell parts. Vacuole • Temporarily stores food, water, and waste • Rather large in plant cells Cytoskeleton • Framework for the cell • Helps to maintain shape or change shape of cell Levels of Organization Organelle Cell Tissue Organ Organ System Organism Tissue • A group of cells working together to perform a particular function Organ • 2 or more tissues working together to perform a function
