Objectives Define Cell Differentiation.  Explore terms related to cell differentiation.  Recognize structures within cell differentiation.  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.  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.  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. New Vocabulary Continued  Sensory receptor cells: develops nervous system and allows use of senses such as taste, smell, and feeling. Types of specialized cells  Blood cells  Red and white Nerve cells  Skin cells  Gland cells  Sensory receptor cells  Bacteria  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  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. 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
