Presentation Transcript

  1. Cell structure and function(Eukaryotic cells) Standard 4 Key idea 1 Major understanding 1.2f, 1.2g, 1.2i, and 1.2j Notes: This power point presentation is made by Eunah Kim.

  2. Bell Ringer question Write down things inside a cell you already know.

  3. Organelles of a cell 1. Plasma membrane: the outer membrane of the cell 2. Cytoplasm Things inside the cytoplasm: a. Centriole b. Ribosome c. Mitochondrion d. Vacuole e. Endoplasmic reticulum f. Golgi complex g Lysosome h. Chloroplast (only for plants) 3. Nucleus Things inside the nucleus: DNA

  5. Activity Label each organelle and write its function on the cell diagram booklet.

  6. Special organelles • Mitochondria: found in all eukaryotic cells (both in plant cells and animal cells) Function: extraction of energy from nutrients through cellular respiration (chemical respiration). Power house of a cell. http://micro.magnet.fsu.edu/cells/mitochondria/mitochondria.html

  7. Special organelles • Chloroplast: found only in plant and algae cells Function: photosynthesis/ contains chlorophylls http://www.nature.com/scitable/topicpage/plant-cells-chloroplasts-and-cell-walls-14053956

  8. Cell wall: found primarily in plants. Function: provides support and protection. http://geneticssuite.net/node/11

  9. Cellular communication • How do cells communicate with each other? Receptor molecules (proteins embedded in the plasma membrane) play an important role in the interactions. between cells. http://www.ftmguide.org/hormonebasics.html

  10. Cellular communication con’t Receptor molecules recognize specific hormones or neurotransmitters and deliver the information to the interior of the cell. Two types of agents of cellular communication: • Hormones i.e.) growth hormone • Neurotransmitters i.e.) acetylcholine

  11. Cellular communication con’t • Hormones i.e.) growth hormone Chemicals that are secreted by endocrine glands and delivered through the blood to affect target cells. 2) Neurotransmitters i.e.) acetylcholine Chemicals that are secreted from one neuron cell and carry the impulse to the next neuron.

  14. Exit ticket • Write two organelles that are only found in plants. • Write those organelles’ functions.
