Acritarchs are small organic structures found as fossils. In general, any small, non- acid soluble (i.e. non carbonate, non-silicate) organic structure that can not otherwise be accounted for is an acritarch. Most acritarchs are surely remains of single celled lifeforms. They are found in sedimentary rocks from the present back into the Precambrian. They are easily isolated from limestones with hydrochloric acid, and can also be isolated from silica rich rocks using hydrofluoric acid. They are excellent candidates for index fossils to be used for formation dating in the Palaeozoic and when other fossils are not available. They are also useful for palaeoenvironmental interpretation. Acritarchs include the remains of several quite different kinds of organisms including bacteria and dinoflagellates. The nature of the creatures associated with older acritarchs is generally not clear, though many are probably related to unicellular marine algae. ...more on Wikipedia about "Acritarch"
Aerial roots are roots that are formed in and exposed to air. They are found in diverse plant species, including epiphytes also known as air plants, which includes the orchids, tropical coastal swamp trees such as mangroves and the resourceful banyan tree, and vines like irritating poison ivy. ...more on Wikipedia about "Aerial root"
Aeroplankton is the term used to describe the tiny lifeforms which float and drift in the air, carried by the current of the wind; it is the atmospheric analogue to oceanic plankton. ...more on Wikipedia about "Aeroplankton"
Agrostology is the scientific study of grasses. It typically encompasses the true grasses (the family Poaceae), as well as the more grasslike species of the sedge family ( Cyperaceae), the rush family ( Juncaceae), and the bulrush or cattail family Typhaceae. Grasslike plants are also referred to as graminoids. ...more on Wikipedia about "Agrostology"
The algae (singular alga) consist of several different groups of living organisms that capture light energy through photosynthesis, converting inorganic substances into simple sugars using the captured energy. Algae have been traditionally regarded as simple plants, and some are closely related to the higher plants. Others appear to represent different protist groups, alongside other organisms that are traditionally considered more animal-like ( protozoa). Thus algae do not represent a single evolutionary direction or line, but a level of organization that may have developed several times in the early history of life on earth. ...more on Wikipedia about "Algae"
The term allelopathy denotes the production of specific biomolecules by one plant that can induce suffering in, or give benefit to, another plant. Conceptually, biomolecules (specifically termed allelochemicals) produced by a plant are released into the environment and subsequently influence the growth and development of neighbouring plants. It is important to keep in mind that allelopathy involves the addition of a chemical compound or compounds (secondary metabolites) into the environment, while "competition" involves the removal or reduction of some factor or factors in the environment (such as nutrients, water, or light). ...more on Wikipedia about "Allelopathy" My http://www.shortopedia.com and me.

Alternation of generations is a term applied to a reproductive cycle of certain plants, fungi, and protists. It is a bit of a misnomer, a more accurate name would be "alternation of phases of a single generation" because a generation of a species typically encompasses one complete life cycle (i.e., both alternating phases; see Biological life cycle). The life cycle of organisms with so-called "alternation of generations" is characterized by each phase consisting of two separate, free-living organisms: a gametophyte (or genetically haploid) thallus or plant and a sporophyte (or genetically diploid) thallus or plant. The distinction of "free-living" is important, because all sexually reproducing organisms involve alternating phases, at least at the cellular level (see meiosis). However, not all biologists agree. It is often stated that alternation of generations refers to both the diploid and haploid stages being "multicellular" and this is more important than "free-living" (Raven, Evert, & Eichhorn, 2005). Such a distinction changes the concept to one separating animals and plants. All plants have diploid sporophyte and haploid gametophyte stages that are multicellular, and the differences between plant groups are in the relative sizes, forms, and trophic abilities of the gametophyte or sporophyte forms, as well as the level of differentiation in the gametophytes (i.e., pollen and ovules vs. bisexual gametophyte thalli). Both approaches are discussed in this article. ...more on Wikipedia about "Alternation of generations"

The Angiosperm Phylogeny Group is an international group of systematic botanists who have come together to try to establish a consensus view of the taxonomy of flowering plants in the light of the rapid rise of molecular systematics. ...more on Wikipedia about "Angiosperm Phylogeny Group"

The antenna complex is an array of chlorophyll molecules embedded in the thylakoid membrane that transfer energy to a pair of chlorophyll a molecules at the reaction center of a photosystem. ...more on Wikipedia about "Antenna complex"
Antitranspirants are compounds applied to the leaves of plants to reduce transpiration. They are used on Christmas trees, cut flowers, newly transplanted shrubs, and in other applications to preserve and protect plants from drying out too quickly. They have also been reportedly used to protect leaves from salt burn and fungal diseases. ...more on Wikipedia about "Antitranspirant"
Apertures are very small spots on the walls of a pollen, where the wall is thinner and/or softer. For germination it is necessary that the pollen tube can reach out from the inner of the pollen and transport the chromosomes to the egg deep down in the pistil. The apertures are the places where the pollen tube is able to brake through the elsewhere very tough pollen wall. ...more on Wikipedia about "Aperture (botany)"
Understanding the principle of apical dominance is helpful when embarking upon any regimen of tree or other plant management. Plants form new tissue in an area called the meristem, located near the tips of roots and shoots, where active cell division takes place. Meristem growth is aimed at ensuring that leaves are quickly elevated into sunlight, and that roots are able to penetrate deeply into the soil. Once adequate height and length is ...more on Wikipedia about "Apical dominance"
In botany, apomixis is biological reproduction without fertilization and without meiosis. An apomict or apomictic plant produces seeds that are genetically identical to the parent plant. Although the evolutionary advantages of sexual reproduction are lost, apomixis does pass along traits fortuitous for individual evolutionary fitness. ...more on Wikipedia about "Apomixis"
