#alga

• Actinella — Romanian name adapted from the taxonomic genus Actinella. In botany, it defines a genus of herbaceous plants (often associated with Hymenoxys) in the Asteraceae family, or a genus of unicellular algae (diatoms) characterized by asymmetric, arched siliceous shells that expand radially at one extremity. In micropaleontology, these fossilized structures are used as environmental indicators.
• Aerocyst — An anatomical structure in the shape of a bladder, pouch, or sac filled with air, found in the stem or leaf structure of certain aquatic plants and marine algae (such as those of the genus Fucus). This floating vesicle functions as a natural hydrostatic organ, keeping the plant at the water surface to capture a maximum amount of sunlight required for photosynthesis.
• Aeroplanctophytes — Microscopic plant organisms, specifically unicellular algae, aerobic bacteria, or fungal spores, structurally adapted to float and survive passively in the lower and middle layers of the atmosphere. These micro-plants utilize air currents for dispersion and colonization, playing a discrete but important ecological role in global aerobiological ecosystems.
• Agar — A natural gelling substance (polysaccharide) extracted from the cell wall of certain species of red algae (Rhodophyta), utilized as a solid culture medium in microbiology, a thickening agent in the food industry, and a stabilizer in chemistry; in a historical and religious sense, represented as a proper noun, it is the biblical name of Sarah's and Abraham's Egyptian maidservant, mother of Ishmael, considered an ancestral structural figure in Judaic, Christian, and Islamic traditions.
• Agar-agar — A mucilaginous polysaccharide product extracted from the cell wall of certain red marine algae (especially from the genera Gelidium and Gracilaria), commercialized as a powder, flakes, or gelatinous strips insoluble in cold water but soluble in hot water. Structurally, it gels upon cooling to form a rigid, thermally stable three-dimensional network, widely used in microbiology as a support for bacterial cultures, in confectionery as a plant-based substitute for animal gelatin (under code E406), and in pharmaceutical technology.
• Algophilous — Manifesting a distinct structural biological affinity, attraction, or optimal evolutionary adaptation for aquatic environments dominated by algae, stagnant ponds, or laboratory algal cultures; a plant, bacterial, or small animal organism that lives, develops, or feeds in close symbiosis with algae. As a masculine noun, it describes an algae-loving microorganism or microscopic species whose cellular architecture is metabolically optimized to absorb organic nutrients released by phytoplankton in aquatic ecosystems.
• Alberta — A major province located in western Canada, bounded by British Columbia and Saskatchewan, with its capital in Edmonton and its largest urban center in Calgary. The region is globally recognized for its spectacular Rocky Mountain landscapes (including Banff and Jasper national parks), its vast wealth in oil, natural gas, and oil sands reserves, as well as its highly developed agricultural and livestock sectors.
• Alga — A lower, cryptogamic thallophyte plant with a body unsegmented into true roots, stems, or leaves, containing chlorophyll and other photosynthetic pigments. It lives primarily in aquatic environments or high-humidity spots. Classified into green, brown, or red variants, it plays a vital role in global ecosystems.
• Algăci — An exclamatory word or regional command historically used by farmers to urge, guide, or drive horses during the traditional grain threshing process. This agrar-pastoral term served as an acoustic communication tool with draft animals.
• Algarade — 1. An unexpected, sudden, and sharp verbal altercation or scolding. 2. Historically, a surprise military attack or cavalry raid carried out during the Reconquista in the Iberian Peninsula. The term acts as a rare expressive loanword denoting impulsive or noisy conflicts.
• Algarve — The southernmost administrative region of continental Portugal, world-renowned for its dramatic Atlantic coastline, golden beaches, and limestone cliffs. Its capital is Faro. Historically, the region retains a strong Moorish heritage, with its name deriving from Arabic 'Al-Gharb' (The West).
• Algotrophic — Feeding on algae or depending nutritionally on algal biomass; algophagous. In aquatic ecology, the term characterizes secondary consumer organisms or trophic webs within a biotope where primary production is overwhelmingly provided by microscopic or macroscopic algae.
• Plot amalgamation — The act of attaching or the state of being attached; a close structural joining of two elements using an adhesive, welding, or mechanical fixation. In cadastre, urban planning, and property law, it represents the technical and legal operation of unifying two or more adjacent land plots to form a single property body.
• Amalgam — An alloy formed by combining mercury with another metal (such as gold, silver, zinc, or tin), historically used in extractive metallurgy and dentistry for fillings; (figuratively) a confused, heterogeneous, and mismatched mixture of different elements, ideas, or feelings.
• To amalgamate — To combine, dissolve, or alloy a metal with mercury; (figuratively) to mix, blend, fuse, or associate completely different elements, ideas, or feelings in a chaotic or heterogeneous manner.
• Amalgamation — The act of amalgamating and its result; the chemical or metallurgical operation of forming an amalgam; (in economics) the process of merging, unifying, or consolidating two or more corporate entities into a single new legal body.
• Amalgamated — Alloyed or combined with mercury; (in economics) merged, unified, or consolidated into a single corporate or financial body; (figuratively) composed of a confused, heterogeneous, mismatched, or incoherent mixture of diverse elements or ideas.
• Amalgamator — A mechanical device or apparatus used in dental clinics for the rapid mixing and dosing, through high-frequency vibrations, of components required to prepare dental amalgam; (as an adjective) having the property or role of blending or unifying heterogeneous elements.
• To amalgamate variant — A non-standardized, rare, or jargonistic verbal variant of 'amalgama', used accidentally in technical or colloquial language meaning to combine a metal with mercury or (figuratively) to blend disparate elements.
• Amalgamation variant — A non-standardized, rare, or jargonistic verbal noun variant of 'amalgamare', designating the hypothetical process of combining a metal with mercury or (figuratively) the blending or merging of heterogeneous elements.
