Cells Elizabeth Tuffnell 5B Science March 30, 2009 Parts of an Animal Cell • Golgi body • Rough Endoplasmic reticulum (E.R.) • Smooth E.R. • Ribosomes • Mitochondria • Vacuole • Nucleus • Cell membrane • Cytoplasm Animal Cells: What the Parts do • Ribosomes help make protiens • Mitochondria change food into a form the cell can use for energy (ATP) • The vacuole stores water and nutrients, and may help digest food • The nucleus directs activities and stores information • The cell membrane holds the cell together and lets things go in and out • Cytoplasm is jelly-like substance in a cell Plant Cell Parts • • • • • • • • Smooth E.R. Rough E.R. Nucleus Mitochondria Golgi body Cytoplasm Big vacuole Cell membrane • Cell wall • Chloroplast Plant Cells: What the Parts do • All of the organelles in the animal cell and the plant cell function the same way in both • The cell wall protects the cell • Chloroplast is used for photosynthesis Differences • • • • • Plant cells Have a cell wall Have chloroplast Color is green Have a bigger vacuole • • • • • Animal cells Don’t have a cell wall Don’t have cloroplast Color is peach (or your skin color) Have a smaller vacuole Other Facts About Cells • Cell is the smallest part of our body • All cells need energy • Cells have limit to how big or small they get
