PPT-CELL STRUCTURE AND FUNCTION

CELL STRUCTURE AND FUNCTION Despite the diversity among cells three basic features are common to all cell types All cells have outer boundary an interior substance and a control region CELL STRUCTURES. OCR AS Biology. Unit 1: Cells, Exchange and Transport. Learning objectives. To understand and discuss the basis of cell theory based upon milestones in cell biology. To carry out practical work on cell size and magnifications using a light microscope. A living thing. Cell. The basic unit of structure and function in living things. Unicellular. Made of a single cell. Multicellular. Consisting of many cells. Stimulus. A change in an organism’s surroundings that causes the organism to react. THE DISCOVERY OF CELLS. In 1665, Robert Hooke began a series of observations using a microscope. Although he was not the inventor of the microscope nor the first to use it, he was the first to describe the basic unit of life, the cell.. By: . Hemangi. . Atalia. introduction. Cell is the structural and functional unit of life.. Cells Tissue Organ . Organ. system.. Cells contain a variety of Internal Structures called . A. Generalized Structure. 1. Cell Appendages. A) Flagella. 1) Functions in movement of the cell. 2) 3 components. Prokaryotic Cell Structure. a) Filament . i) Whip-like, helical structure. b) Hook . i) Holds the filament. Part II: Proteins & Nucleic Acids. The FOUR Classes of Large Biomolecules. All living things are made up of four classes of large biological molecules: . Carbohydrates . Lipids. Protein. N. ucleic Acids. Surface markers . Structure . . Variable, integral or glycolipids . In plasma membrane.. Function . Identify the cell . Example . MHC complexes, blood groups, antibodies . Cytoplasm.  . Cytoplasm . material between plasma membrane& nucleus. site of most cellular activity. 3 elements. Cytosol. Organelles. Inclusions . Cytosol. . viscous, semitransparent fluid in which other elements in cytoplasm are suspended. The Structure and Function of Macromolecules Part II: Proteins & Nucleic Acids The FOUR Classes of Large Biomolecules All living things are made up of four classes of large biological molecules: Where is the genetic material in a prokaryotic cell?. In a bacterial DNA loop and there may be one or more plasmid rings.. 2. Where is the genetic material in a eukaryotic cell?. The DNA is in chromosomes enclosed in a nucleus. . Vinay. K. . Chaudhri. 1. Outline. Introduction. KB_Bio_101- Biology textbook knowledge base. Representing structure and function . Representation and Reasoning needs. Upper ontology. Representing structure. Structure. Main component is phospholipids that are arranged in a double layer (. bilayer. ). Has scattered proteins within the phospholipids. Regulate what enters/leaves cell. Function . Nucleus. Structure. Pick up a Cell Rubric and Cell parts Handout. Have your binder open to section 10.4. Begin writing in your planner for the week. . Looking inside the cells. 10.4. How Do the Parts of a Cell Work?. Each kind of cell structure has a different and specialized function within a cell.. Much larger than prokaryotic cells having two enveloped systems. True cells occurring in plants and animals . Though they have different shape size and physiology but all cells are typically composed of plasma membrane cytoplasm and its organelles i.e. mitochondria, endoplasmic reticulum .
