PPT-Chapter 1 – Cell Structure

Introduction Robert Hooke examined slices of cork under a microscope and decided to call the porelike structures cells Robert Hooke through his observations had discovered .

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. 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. Where indicated, complete the statements by inserting the missing word(s) in the answer blanks.. You are miniaturized to the size of a small protein molecule and will travel in a . microsubmarine. , specially . . 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. 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 . 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.. 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). Keywords - cell membrane; cell wall; nucleus; nucleolus; cytoplasm; mitochondria; ribosome; endoplasmic reticulum (smooth and rough); Golgi body; lysosome; vesicles Starter – Why are cells different? The printed out notes are more detailed than these slides, you are expected to read the chapter and your notes - anything is fair game on the test, but the cell chapter is largely review. . Quick: Grab some scratch paper and quickly discuss with your partner what you remember from freshman biology about the cell. . 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. . Cell Parts. Cells. – the basic unit of life. . Organelles. - small structures inside a cell with specific functions.. Analogy – City of Rocklin. Cell . Membrane/Plasma Membrane . Analogy – Rocklin city limits. The ultrastructure of eukaryotic cells. Spec. Animal Cell Plant Cell. Starter. In pairs - Identify the main similarities and differences between animal and plant cells. Animals vs. Plants. 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 .
