3. Escherichia coli is one of the most common intestinal bacteria of warm-blooded animals – only a few of the hundreds of types ( strains ) are harmful
53. 1 meter = 10 2 cm = 10 3 mm = 10 6 μ m = 10 9 nm
54.
55. We use different types of microscopes to reveal different details of their structure
56.
57.
58. Membranes of most cells can be described as a fluid mosaic of lipids (mainly phospholipids) and proteins
59. Lipids are organized as a lipid bilayer : a double layer of lipids in which the nonpolar tails of both layers are sandwiched between the polar heads
106. The outer bilayer of the double membrane is continuous with the membrane of the ER

Figure 4.1 E. coli O157:H7 bacteria ( red ) clustering on intestinal cells of a small child. This type of bacteria can cause a serious intestinal illness in people who eat foods contaminated with it.
Figure 4.2 Examples of cells. Each one of the cells pictured here is an individual organism; all are protists
Figure 4.3 Overview of the general organization of bacteria and eukaryotic cells. Archaeans are similar to bacteria in overall structure. The three examples are not drawn to the same scale.
