| A slender, rootlike filament by which mosses, liverworts, and the gametophytes of ferns attach themselves to the material in which they grow. A branching, rootlike extension by which algae and fungi absorb water and nutrients. | rhizoid |
| The vegetative part of a fungus, consisting of a mass of branching, threadlike hyphae. A similar mass of fibers formed by certain bacteria. | mycelium |
| is a long, branching filamentous structure of a fungus, and also of unrelated Actinobacteria.[1] In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium; | hypha |

| (in animals and embryos) pertaining to or toward the head or forward end of the body. (in humans) pertaining to or toward the front plane of the body, equivalent to the ventral surface of quadrupeds. | anterior |
| (in quadrupeds) pertaining to or toward the rear or caudal end of the body. (in humans and other primates) pertaining to or toward the back plane of the body, equivalent to the dorsal surface of quadrupeds. | posterior |
| situated on or toward the upper side of the body, equivalent to the back, or posterior, in humans. situated on or toward the posterior plane in humans or toward the upper plane in quadrupeds. | dorsal |
