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. 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.. . Cell Structure. Enormous variety in the size and shape of different cells. Smallest cells belong to group of . organisms. . Mycoplasma. Only about 0.2 µm in diameter. So small that often beyond the limit of resolution of light microscopes. 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. Dolgushin. Harvard SIG 2013. History of Cell Theory. . CITOLOGY. . (. cito. - and –logos-. ) – . the science about the cell. Hooke. , Leeuwenhoek, Schleiden, Schwann, . Virchow. All living things or organisms are made of cells and their . Surface markers . Structure . . Variable, integral or glycolipids . In plasma membrane.. Function . Identify the cell . Example . MHC complexes, blood groups, antibodies . Unit Objectives. 1: Explain the structures of plant cells and important cell processes.. a. Describe the structures of a typical plant cell and their functions.. b. Compare and contrast mitosis and meiosis.. Keywords - cell membrane; cell wall; nucleus; nucleolus; cytoplasm; mitochondria; ribosome; endoplasmic reticulum (smooth and rough); Golgi body; lysosome; vesicles Starter – Why are cells different? 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. . 24 . Nov. 2014, CERN. Toshi Higo (KEK). 2014/11/23. CLIC Structure Review. 1. Contents . Transition from GLC/NLC . to CLIC. Alignment target.

Extended Learning — Activities and Projects1.Visit a laboratory for senior secondary students in your school orin a neighbouring school. Learn about the functioning of aunder the microscope.2.Tal Van Delden C, Iglewski BH. Cell-to-Cell Signaling and Pseudomonas aeruginosa Infections. Emerg Infect Dis. 1998;4(4):551-560. https://doi.org/10.3201/eid0404.980405. •All living things are made of cells.. •Cells are the basic units of life.. •Cells come only from other cells. . Since the microscope was introduced biologists have examined the structure of living things. In most cases they have been found to be compose of cells. There are however some strange exceptions to the general cell pattern..
