  1. TEACHER PREPARATION • Run-off the Cell Venn Diagram – Cell Function Table and Questions • You will need two fly swatters & a copy of the printed questions-answers for the SWAT game.

  2. These are the questions that the teacher will read for the Swat Game – Answers Provided

  3. Biology 4B Investigate and Identifycellular processes including homeostasis and function of cellular parts.

  4. Maintaining a stable internal environment Organisms must be able to do this or they die Examples: You get too hot, you sweat You get too cold, you shiver You take in too many fluids you urinate more often You run and your heart speeds up to get oxygen to all parts of your body HOMEOSTASIS Your home keeps you safe; homeostasis keeps your body safe

  5. Use the next slide to list the organelles names in the correct category on your Venn diagram.

  6. Homeostasis • Cells must maintain a stable internal environment • Cells depend on their organelles to keep them alive and make adjustments to the environment • On the next few slides, add to your Venn diagram chart by writing the job/function of each organelle by its name and drawing a picture of the organelle.

  7. How are plant & animal cells alike & different? Place the organelle names on the Venn diagram.

  8. The cell wall surrounds both plant & fungi cells. It is outside of the cell membrane Its is made of a stringy material called cellulose. Its function is to support the cell – animal cells are attached to bones for support Cell Wall Cell Membrane

  9. The cell membrane surrounds all cells Its job/function is to control and enter what leaves a cell It is an example of an organelle that exhibits homeostasis and keeps a cell alive. If it lets in poisons or lets out or in too much water the cell dies. Cell Membrane Cell Membrane

  10. Found in both plant and animal cells. (hot dog shaped) Its function is to break down glucose into an energy form the cell can use. (ATP) Active cells have lots of mitochondria. Example: Muscle cells Mitochondria

  11. Found only in plant cells. (Green-contain chlorophyll) Its function is to use sunlight to turn water & carbon dioxide into glucose. (Photosynthesis) Chloroplasts

  12. Found in all cells. Look like small dots on the Endoplasmic Reticulum. Can be found free-floating too. Its function is to link amino acids together and form proteins. (Protein synthesis) Ribosomes get their directions from the DNA Ribosomes

  13. Found in all eukaryotic cells. Control center of the cell This is where the DNA is found in eukaryotic cells Nucleus

  14. Cilia – tiny hair-like structures used for movement Top picture-human respiratory cells with cilia to wave dirt and mucous out of the lungs Bottom picture – a single – celled Paramecium that uses cilia for swimming Cell Locomotion or Movement

  15. Flagella – long, thin hair-like structures used for movement Top picture-human sperm cells with flagella used for swimming to the egg Bottom picture – different species of E. Coli bacteria with varying number of flagella Cell Locomotion or Movement

  16. Eukaryotic Cells – are cells with true nucleus-like the two cells shown below

  17. Prokaryotic Cells – primitive cells without a true nucleus; they have free-floating DNA but NO nucleus-Bacteria DNA No Nucleus

  18. Binary Fission – How prokaryotic bacteria cells reproduce • They make a copy of their DNA and split • The two cells are clones of one another

  19. Practice Questions The swordfish has a heat-generating organ that warms its brain and eyes up to 14°C above the surrounding water temperature? What structures are likely to be found in high concentrations in the cells of this organ? A. Chromosomes B. Mitochondria C. Nuclei D. Ribosomes

  20. Practice Questions What process is shown? A. Cellular Ingestion B. Psuedopod Formation C. Cell Wall Digestion D. Binary Fission

  21. Practice Questions The diagram shows different parts of human sperm cell. Which part is most likely specialized for mobility? A. Q B. R C. S D. T

  22. Practice Questions Which of these is a function of the cell membrane in all cells? A. Providing cellular nutrients B. Preserving cellular wastes C. Neutralizing chemicals D. Maintaining homeostasis

  23. Practice Questions Energy conversion, within an animal cell, would be severely limited by removal of the cell’s? A. mitochondria B. chloroplasts C. plastids D. lysosomes

  24. SWAT GAME • Your teacher will divide you into two teams • Each team will number off starting with the number 1. • Number 1 will go to the screen first and compete against number 1 on the other team • Your teacher will read a definition. When you know the answer – swat it on the screen. The first team to SWAT it will receive a point. • The above steps will then be repeated with Player 2 on each team. Then Players 3 etc.
