Presentation Transcript

  1. Ms. Ethridge Ms. Milstead Ms. Myers Ms. Palermo Cell Differentiation

  2. Objectives • Define Cell Differentiation. • Explore terms related to cell differentiation. • Recognize structures within cell differentiation.

  3. Think-Pair-Share! • Get with a partner and discuss together what you think happens in cell differentiation. Begin filling out your KWL chart – fill in what you already know and what you want to know. • There will be time at the end of class to fill in what you learned.

  4. What is Cell Differentiation? • A process by which a less specialized cell matures to a more specialized cell. • Forms a more distinct form and function.

  5. New Vocabulary • Protein synthesis: formation of protein cells within your body to aid in the formation of bodily organs such as hair, skin, and blood.

  6. New Vocabulary Continued • Sensory receptor cells: develops nervous system and allows use of senses such as taste, smell, and feeling.

  7. Types of specialized cells • Blood cells • Red and white • Nerve cells • Skin cells • Gland cells • Sensory receptor cells • Bacteria

  8. So, how does a cell turn into a specialized cell? • Cell Division • Meiosis and mitosis • Genes/DNA • Protein Synthesis • Collagen in skin • Keratin in hair • Hemoglobin in blood • http://www.wisc-online.com/Objects/ViewObject.aspx?ID=AP1302

  9. Cells “talk” to each other! • Embryo develops and cells know exactly where they are. • Chemical messages are sent from cell to cell. • Messages spread from cell to cell to the nucleus which turns genes on or off. • Chemical messages tell the cells exactly what to do according to their location. • Heart beating, lining of intestines, skin, etc. • This is how organs are formed from cells.

  10. Lab Activity • Groups of 3-4 • Each group will be assigned an organ • Construct your organ using materials I have provided • Must include: • At least 5 cells • Nucleus (5) • Mitochondria (5) • Cell wall/membrane • Golgi • Examples of proteins it produces • Must identify whether it is prokaryotic or eukaryotic
