Cover Description: Lichens and club fungi are growing on the bark of this tree. In some cases, the two organisms that make up a lichen can live separately, but look very different than the lichen. Club fungi are saprobe (sapro- "putrid, rotten" + be), which play a vital role in the decomposition of litter, wood, and dung.

14 | 64 | cuticle | waxy, protective layer that covers the stems, leaves, and flowers of many plants and helps prevent water loss. |
31 | 67 | nonvascular plant | plant that absorbs water and other substances directly through its cell walls instead of through tubelike structures. |

47 | 68 | rhizoids | threadlike structures that anchor nonvascular plants to the ground. |
38 | 69 | pioneer species | first organisms to grow in new or disturbed areas; break down rock and build up decaying plant material so that other plants can grow. |
23 | 75 | guard cells | pairs of cells that surround stomata and control their opening and closing. |
56 | 75 | stomata | tiny openings in a plant's epidermis through which carbon dioxide, water vapor, and oxygen enter and exit. |
