Peptidoglycan is found only in bacterial cells. are so small that they cannot be seen with the light microscope and are cultivated only within living cells. However, the bacterial cell is the entire organism; that senses the environment, obtains food, gets rid of waste, and reproduces. Describe the different types of bacteria. Outermost component common to all bacteria (except Mycoplasma species). Each type of human cell is specialized to Bacteria Cell Parts – Functions. Prevents them from being engulfed by larger cells like white blood cells. The peptidoglycan provides structural support and maintains the characteristic shape of the cell. Discuss bacterial Bacterial Plasma Membranes. Prevents them from being engulfed by larger cells like white blood cells. Differentiate between a capsule and slime layer. entire bacterium and gives the organism its shape Composed of peptidoglycan. (3) Synthesis of precursors of the cell wall. In contrast, a human being is composed of approximatelytrillion cells. Distinguish macroelements (macronutrients) from micronutrients (trace elements) and provide examples of each. Capsule: protects some bacteria so they do not dry out. (2) Energy generation by oxidative phosphorylation. Plasma or Cytoplasmic Membrane: Like the cell membrane Cell Wall. Capsule: protects some bacteria so they do not dry out. It is a network that covers the. Bacterial cell looks simple compared to those within our nervous system. Most species in the phylum are pathogens and one species causes the gonorrhea-like dis-ease known as chla mydia Cells are incredibly variable. Roughly half the size of the rickettsiae, members of the phylum Chlamydiae. (4) Secretion of enzymes Describe the structure of bacterial flagella and discuss how they function in chemotaxis. Provide examples of growth factors needed by some microorganisms Chlamydiae. Bacterial cell looks simple compared to those within our nervous system. However, the bacterial cell is the entire organism; that senses the environment, obtains food, gets rid Bacteria Cell Parts – Functions. Describe the fluid mosaic model of membrane structure and identify the types of lipids typically found in bacterial membranes. Identify their roles in cell survival The lecture will: Cover different classification schemes for grouping bacteria, especially the use of the Gram stain. Cell Wall: wall functions: (1) Active transport of molecules into the cell. Cell Wall: wall gives the cell its shape and surrounds the plasma/cytoplasmic membrane, protecting it from the environment.
