Fungi (kingdom Fungi) are heterotrophs. They cannot manufacture their own food as photosynthetic organisms can. Most species of fungi are saprotrophic; they decompose dead matter. Many are parasitic; they obtain nutrients from living organisms. Fungi are the principle decomposers in every ecosystem. They can break down most organic compounds including lignin, a compound that is a major component of wood and is very difficult to break down or...

By switching genes off when they are not needed, cells can prevent resources from being wasted. There should be natural selection favoring the ability to switch genes on and off. Complex multicellular organisms are produced by cells that switch genes on and off during development. A typical human cell normally expresses about 3% to 5% of its genes at any given time. Cancer results from genes that do not turn off properly. Cancer cells have...

Notice that the larger cube has more surface area and more volume but less surface area for each cubic centimeter of volume. For any given geometric object (cubes, spheres, etc.), smaller objects have a greater surface to volume ratio (surface:volume) than larger objects of the same shape. Every cell is surrounded by a plasma membrane (discussed below and in the next chapter). Most cells are very small and therefore have a high ratio of...
