Cells . The cell is the basic unit of structure and . function of all living things. Cell or plasma membrane. Nucleus. Nucleus . Most important organelle within the cell. Function. Control the activities of the cell and facilitate cell division. 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. 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.. The Nucleus: the gene-containing control center of the cell.. The nucleus is bound by a double membrane called the . nuclear envelope. . . Inside the nucleus are one or more small, dark-staining, essentially round structures called . homeostasis. . Cells have different functions.. Homeostasis = stable environment in your body; balance. Your body maintains its homeostasis even if outside conditions are changing. . Levels of Organization. Structures, Functions and Organelle Relationships. p.50-50 in textbook. Animal Cell. Plant Cell. Cell Membrane & Cell wall. The cell membrane (plasma membrane) creates a cell boundary and helps to regulate the transport of molecules in and out of the cell (in plant & animal cells). Cells Homeostasis Cells work together to maintain homeostasis . Cells have different functions. Homeostasis = stable environment in your body; balance Your body maintains its homeostasis even if outside conditions are changing. 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—. stable internal environment.. Homeostasis. Homeostasis represents a state of . DYNAMIC EQUILIBRIUM.. Homeostasis. Homeostasis represents a state of . DYNAMIC EQUILIBRIUM.. . This means that adjustments are always being made to keep the variables within an . Warm-Up. What do you know so far about the cell membrane?. What do you want to know about the cell membrane?. Cell Membrane Structure & Function. Phospholipid. Bi-layer . (hydrophilic heads, hydrophobic tails). According to Merriam-Webster homeostasis is “the maintenance of relatively stable internal physiological conditions (as body temperature or the pH of blood) in higher animals under fluctuating environmental conditions; . ASSESSMENT. Complete the chart covering viral vs. bacterial pathogens!. 5 minutes. WHAT IS ONE CRITICAL THING THESE PEOPLE. DO. . IN ORDER TO “PLANK” ON AN OBJECT?. CHECK THIS OUT!!!. THESE PEOPLE ARE CRAZY! .
