  2. What is the difference between a plant cell and an animal cell? Explain • Discussion: http://www.youtube.com/watch?v=-zafJKbMPA8&feature=related

  3. Chapter 2 “Cells”Section 1: “Cell Structure Pages 38 – 40 LESSON 1

  4. COMMON CELL TRAITS • A cell is the smallest unit that is capable of performing life functions.

  5. COMPARING CELLS • The size & shape of a cell relates to its function. (job it does)

  6. Prokaryotic Cells(proh KAYR ee yah tihk) • cells without membrane-bound structures • EX: bacteria pond scum

  7. Eukaryotic Cells(yew KAYR ee yah tihk) • cells with membrane-bound structures • EX: animals, plants, fungi and protists

  8. CELL WALL • protects the cell • gives shape • is made of cellulose • A cell wall is found in plants, algae, fungi, & most bacteria.

  9. CELL MEMBRANE • Outer covering, protective layer around ALL cells • For cells with cell walls,the cell membrane is inside the cell wall • Allows food, oxygen, & water into the cell & waste products out of the cell.

  10. CYTOPLASM • gelatin-like inside cell membrane • constantly flows • aka protoplasm

  11. NUCLEUS • Directs all cell activities • Contains instructions for everything the cell does • These instructions are found on a hereditary material called DNA • Usually the largest organelle

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

  13. 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

  14. 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

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

  16. NAME THE ORGANELLE a. Nucleus c. Cell Wall b. Chloroplast d. Mitochondria

  17. How do Cell’s relate to Human Body protects but also allows some things to go in and out Skin Brain Controls all functions fluid that supports and protects Blood Bladder Holds liquid produces energy Enzymes

  18. 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

  19. Color Code Cells Diagrams Cell Membrane Nucleus Cytoplasm Vacuole Mitochondria Cell wall Chloroplast
