  1. LESSON 2 “Cell Structure” Pages 41 – 45

  2. CHLOROPLASTS • Green organelles that make food • found only in plant cells

  3. CHLOROPHYLL • A green pigment that gives leaves & stems their color • Captures sunlight energy that is used to produce food called glucose • Glucose is a type of sugar

  4. MITOCHONDRIA • Organelles that release energy from food • This energy is released by breaking down food into carbon dioxide • AKA the powerhouse b/c they release energy from food • Some muscle cells have 20,000 mitochondria

  5. RIBOSOMES • Make proteins • Float freely or attached to the endoplasmic reticulum (ER) • Ribosomes are made in the nucleolus

  6. ENDOPLASMIC RETICULUM • A series of folded membranes that move materials (proteins) around in a cell • like a conveyor belt • Smooth ER – ribosomes not attached to ER • Rough ER – ribosomes attached to ER

  7. GOLGI BODIES (GAWL jee) • Stacked flattened membranes • Sort and package proteins

  8. VACUOLES • Temporary storage spaces • Store food, water, waste

  9. LYSOSOMES (LI suh sohmz) • The word "lysosome" is Latin for "kill body." • The purpose of the lysosome is to digest things. They might be used to digest food or break down the cell when it dies. • Break down food molecules, cell wastes & worn out cell parts

  10. FROM CELL TO ORGANISM Tissue Group of cells working together Organ Group of tissues working together Organ System Group of organs working together Organism Any livingthing made of 1 or more cells

  11. NAME THE ORGANELLE a. Nucleus c. Golgi body b. Chloroplast d. Mitochondria
