PPT-The Cell Membrane Homeostasis & Cellular Transport

Function of the Cell Membrane Cell membrane separates the components of a cell from its environment surrounds the cell Gatekeeper of the cellregulates the flow of materials into and out of cell. Passive and Active Transport. Lesson Objectives . Understand how equilibrium is established as a result of diffusion.. Distinguish between diffusion and osmosis.. Cellular Membrane. Membrane: function is to control what enters and exits the cell. 1. Cilia Organelles. Centrioles Ribosome. Cellulose Lysosome. Nucleus Vacuole. Protein Synthesis Mitochondrion. Autolysis Centrosome.

Homeostasis & Cellular Transport. Function of the Cell Membrane:. Cell membrane separates the components of a cell from . its . environment. —surrounds the cell. “Gatekeeper” of the cell—regulates the flow of materials into and out of cell—. Chapter 7. 7.1 Cell discovery and theory. The invention of the microscope led to the discovery of cells. .. microscope . Compound Light Microscope. Series of glass lenses. Uses visible light to produce a magnified image. Revision (part 1). Nick Richards & Byron Haywood-Alexander. Topics. Cells. Homeostasis. Molecular building blocks. DNA/RNA. Mitosis/Meiosis. Genetic disease. 1. Cells. Functional unit of the body, compartmentalised by a cell membrane, containing intracellular organelles and cytoplasm. Many cellular metabolic processes occur here including those that allow molecules into and out of the cell.. http://www2.nursingspectrum.com/articles/article.cfm?aid=11971. http://ailil.deviantart.com/art/Osmosis-Jones-Strikes-Back-3678440. Section 1 Vocabulary Pretest. Passive Transport. Diffusion. Concentration gradient. What is the plasma membrane?. A flexible boundary between the cell and its environment which maintains . HOMEOSTASIS. within the cell. **Remember that . HOMEOSTASIS. is a state of balance/equilibrium within the cell.. Plasma membranes :. Membranes. cover the surface of every cell and also surround most organelles within cells. They have a number of functions, such as:. keeping all cellular components inside the cell. mitos. ' which means 'thread' and '. chondrion. ' which means 'granule'. . The . mitochondrion. (plural . mitochondria. ) is a membrane-enclosed structure found in most eukaryotic cells Mitochondria range from 0.5 to 1.0 . Where does the name “cell” come from?. “Cells” were named by Englishman Robert Hooke in 1665.. He observed that cork wood looked like monk’s cells in a monastery.. The Cell Theory. The cell is the basic unit of structure and function.. Students will describe the structure and function of cells, tissues, organs, and organ systems.. . Explain that cells take in nutrients in order to grow and divide and to make needed materials.. Relate cell structures (cell membrane, nucleus, cytoplasm, chloroplasts, mitochondria) to basic cell functions. . ASSESSMENT. Complete the chart covering viral vs. bacterial pathogens!. 5 minutes.
