Presentation Transcript

  1. Walk-In • Take out notebook, pencil box and folder, agenda. • Copy the question and answer in sentences: • What are two differences between animal and plant cell organelles?

  2. Answer • Plant cells contain the CELL WALL and CHLOROPLASTS, which are not present in animal cells.

  3. Parts of a Cell

  4. Review - The Cell Theory • All living things are made of cells. • Cells are the basic units of structure and function in living things. • Living cells come only from other living cells.

  5. Cell Organelles • Cells are made up of organelles, which are like tiny organs, each with its own job. • We can compare organelles to parts of a city, to understand the job the organelle does.

  6. Organelles in a Plant Cell Organelles in an Animal Cell What do all these structures do anyway??!!?

  7. Cell Function sheet • The sheet, Cell Structures and Functions, has a chart with • Notes to write about all organelles found in animal and plant cells, • Columns to check off if it is found in an animal cell, or plant cell, or both. • A box for a picture clue of something found in a city to help remember the function. (Get your picture clue sheet after your notes are done. Cut apart and glue into the correct places.)

  8. What are the functions of the organelles? • LAPTOP activity: • Go to class webpage, www.kyrene.org/sryan • Find this presentation for today’s date. • Read each slide together and take the time to understand what it says! • Take notes by filling in blanks on your sheet. • AFTER ALL NOTES ARE DONE, get your sheet of picture clues (from the basket on demo table) to cut out and glue in the appropriate box on your sheet.

  9. Here come the organelles…!

  10. Cell Wall • Plant cells only • Give plants their shape, structure, support, and protection • Surrounds the cell membrane • Allows H2O, O2, and CO2, to pass in and out of the cell

  11. Cell Membrane • A continuous, almost invisible structure surrounding the cell • Supports & protects the cell • Controls movement of materials in and out of the cell

  12. Nucleus • The cell’s computer, brain, or manager. Uses DNA to control the cell’s activity • Contains all the information the cell needs to do specific jobs, grow, and divide • Information is stored in DNA molecules • Contains the nucleolus which makes ribosomes • Determines what proteins will be made

  13. Nuclear Membrane • Protects and guards the nucleus. Allows materials to pass in and out. • Keeps the DNA inside the nucleus • Allows other materials to pass in and out of the nucleus

  14. Cytoplasm • The cell’s environment or inner space. • Mostly made of water and contains organelles • The jellylike material outside the cell nucleus.

  15. Chloroplasts • Plant cells only • Uses energy from the sun to make food for the plant through photosynthesis • Where photosynthesis takes place • Power generator for the plant • Give plants their green color

  16. Mitochondria • Powerhouse of the cell. Supplies energy that the cell needs. • Breaks down sugar molecules into energy • Need oxygen to make energy and give off carbon dioxide as waste

  17. Ribosomes • Produces protein, to repair the cell and to direct chemical processes. • Cells need protein to survive and grow Protein Protein

  18. Vacuoles • Storage bubbles found in cells. • Much larger in plant cells. • Store nutrients a cell might need to survive. • Store waste products so the rest of the cell is protected from contamination.

  19. Golgi Bodies Packs • Packs and carries proteins in little bubbles that separate and float into the cytoplasm. • Prepares the proteins for use or delivery outside the cell

  20. Endoplasmic Reticulum (E.R.) • Transportation system of the cell. Carries material through the cell. • Rough ER has ribosomes attached to it so the proteins they make can be released directly into the ER for transport • Smooth ER collects things and contains them

  21. Lysosomes • Cell’s recycler. Breaks down large food and digests old cell parts. • Contains enzymes which break down the proteins

  22. OBSERVE The Differences between Animal & Plant Cells

  23. Now get your sheet of pictures! Protein Cut out the symbols and glue them next to the correct cell part, to help you remember the function of the organelle. Hint: Go back to the slide to see which picture goes with it!

  24. Answer Key * Check if you have all the symbols in the right boxes. * Check if the organelle is in animal cells, plant cells or both. * Then quiz a partner about the function of each of these organelles, by taking turns asking questions and using your paper to check the answers.
