At the molecular level, cells from different types of organisms vary in their tolerance to temperature and pH. This variation can mostly likely be attributed to the types of enzymes present in the cells.
- The tolerance ranges for abiotic environmental factors are similar to the geographic ranges that organisms have.
- To put it another way, they can tolerate (or survive in) a specific range of a given factor, but they cannot survive if the element is present in either an excessive or insufficient amount.
- Take temperature, for example. Polar bears thrive in cold climates but would perish in the tropics from excessive heat.
- Cells are incapable of acting as "liquid machinery" at temperatures below freezing and above boiling.
- The majority of cells, however, are still unable to function across the entire range of liquid temperatures.
- Variance in enzyme activity and protein denaturation are most closely related to variation in cells' capacity to vary in their tolerance to temperature, etc. at the molecular level in various animals.

A cross section of a leaf shows that it is a complex organ built of several different kinds of specialized tissues. The tissues, in turn, are built of specialized cells, and the cells, of organelles. Epidermis covers the upper and lower surfaces of the leaf.
