Botanical Terms - acidic grassland
An acid-soil grassland ecosystem that is typically formed from old woodlands via centuries of grazing and, to a lesser degree, fire. Agrostis (bent) and Festuca (fescue) species are the predominant grasses in Britain and a large portion of northwest Europe.Although the related plant species are typically different, and the term "grass heath" is seen to be more fitting, this type of vegetation is most prevalent in highland locations. The grasses that are typical of the acidic areas of the prairie in North America are supina bluegrass (Poa supina), Elliott's broomsedge (A. elliotti), and Canada bluegrass (P. compressa)

Botanical Terms - Acetobacter (family *Acetobacteraceae)
A genus of Gram-negative, *aerobic *bacteria. Cells are ovoid or rod-shaped, motile or non-motile. Most strains can oxidize ethanol (ethyl alcohol) to carbon dioxide, forming acetic acid as an intermediate. Some species are used in the manufacture of vinegar. They are found on fruits and vegetables, in alcoholic beverages (in which they can cause spoilage), etc.

Botanical Terms - acentric
applied to a segment of a *chromosome without a *centromere that is created during cell division. Because it no longer has a point of attachment to the *spindle, the fragment will not be able to migrate with the rest of the chromosomes towards either pole.

Botanical Terms - Acervulus
an asexual, conidia-bearing structure that some plant-parasitic *fungi create. It is composed of a mat of fungal tissue bearing a layer of *conidiophores, which are generated inside the tissues of plants and then break through to release conidia.

, Botanical Terms - Acetabularia
often known as the mermaid's wineglass or cup
a genus of *dasycladalean algae where the mature *thallus is made up of a whorl of *gametangial sacs at the summit of a single *axis, or "stalk." Found affixed to rocks, shells, and other objects in shallow, protected waters in warm climates. There are fossilized Acetabularia from the *Tertiary period.
