PPT-Chapter 8: Movement through cell membranes

Leaving Certificate Biology Higher Level Selective Permeability Cell membranes are selectively permeable meaning they can control what enters and leaves the cell Selective permeability is controlled by proteins embedded in the cell membrane.

The downfall is that they do not magnify a tremendous amount. . 2. Magnification. . is the ratio of an object’s image to its real size. A light microscope can magnify effectively to about 1,000 times the real size of a specimen. . Figure 4.13c. Figure 4.13b–c. Gram-Positive Gram-Negative . Cell Walls Cell Walls. Thick peptidoglycan.
