• Agamous — Reproducing without sexual cells or fertilization; a plant or animal organism whose multiplication is achieved asexually, through cell division, budding, or spores. In a general sense, it describes the structural biological process that does not involve the alternation or fusion of gametes.
• Agama — An insectivorous lizard from the agama family (Agamidae), characterized by a large head, structurally flattened body, and long tail, widespread in hot and arid regions of Africa, Asia, and Australia; also the feminine form of the adjective 'agam', describing a biological phase or organism characterized by asexual reproduction without gamete involvement.
• Agamete — An asexual reproductive cell (such as a spore, zoospore, or conidium) capable of directly giving rise to a new living organism without previously fusing with another sexual cell. Its functional structure is specific to lower plants, fungi, and protozoans that utilize alternation of generations in their biological cycle.
• Agametangia — A rare plural or adjectival form used in botany to denote asexual organs or cellular structures inside which agametes (spores or zoospores) are formed in lower plants, fungi, or algae. The term describes the non-sexual reproductive apparatus before modern morphological standardization.
• Agametangium — An asexual reproductive organ (sporangium) found in algae, fungi, and lower plants, inside which exclusively agametes (spores or zoospores) are produced. Its anatomical structure is adapted for protecting and releasing non-sexual multiplication cells, ensuring species perpetuation without fertilization.
• Agamete — A primitive reproductive cell form or an undifferentiated gamete that develops directly, without fertilization, giving rise to a new organism. It represents a biological unit of asexual reproduction, found in certain protozoans, algae, and lower fungi, where multiplication does not involve the fusion of complementary genetic material.
• Agamic — Reproducing without the intervention of sexual cells or the process of fertilization; independent of gametic genetic phenomena. In a structural sense, the term describes organisms, evolutionary phases, spores, or multiplication methods (such as budding or direct division) that perpetuate the species exclusively asexually, generating clones identical to the parental organism.
• Agamy — The absence of sexual reproduction or lack of differentiated reproductive organs in the living world; in a sociological and anthropological sense, it denotes the state of being unmarried or the absence of the institution of marriage within a specific structural community. The term reflects a condition of non-union, either at the cellular level through agamic multiplication or at the social level through the refusal or nonexistence of formal marital bonds.
• Agamont — A plant or animal organism that reproduces through purely asexual means, without the formation or fusion of gametes; a structural biological individuality within the agamic phase of its life cycle. This term defines microbiological or botanical entities whose ontogenetic replication relies exclusively on mitosis, direct division, or autonomous sporulation.
• Agamobium — An organism or generation that is part of an alternation of generations cycle (metagenesis) and reproduces exclusively asexually. Structurally, the agamobium represents the alternating phase that subsequently gives rise to a sexual generation (gamobium), thereby ensuring genetic diversity and the survival of lower invertebrate or parasite species in variable environments.
• Agamocyte — An asexual reproductive cell or specialized spore that develops directly, without prior fusion with another cell, giving rise to a complete new individual. Structurally, agametes produced by lower organisms bear this name during cytological phases in which they exhibit no sexual differentiation or complementary gametic potential.
• Agamophytes — A taxonomic or ecological group of plants characterized by reproduction carried out exclusively through spores or vegetative means, without the intervention of sexual organs or the process of gametic fertilization. Structurally, this category includes lower plant forms (such as certain algae, fungi, and lichens) in whose life cycles the agamic multiplication phase is absolutely dominant or unique.
• Agamogamy — A mode of reproduction within which a structural alternation occurs between two different asexual phases, completely excluding the gametic fusion stage or the genetic recombination specific to sexual reproduction. This rare biological phenomenon ensures the perpetuation of the species through purely mitotic or sporogenic multiplication cycles, found in certain protozoans and unicellular organisms adapted to isolated ecological niches.
• Agamogenetic — Relating to agamogenesis; pertaining to or specific to asexual reproduction, carried out independently of gametic fusion or the recombination of genetic material. In a structural sense, the term describes cellular processes, ontogenetic development cycles, and biological replication mechanisms through which a new organism originates from a single parental cell without meiotic division.
• Agamogenesis — A form of asexual reproduction in which the development of a new organism occurs without the participation of sexual cells (gametes) and without the process of fertilization; a mode of structural biological multiplication found in protozoans, coelenterates, worms, and certain lower plants. This phenomenon includes varied methods such as direct division, budding, or mitotic sporogenesis, guaranteeing the faithful perpetuation of the parental genome.
• Agamospore — A spore formed directly, without any prior gametic fusion or genetic recombination, serving as an autonomous unit of asexual propagation in algae, fungi, and certain lower plants. Structurally, the agamospore retains the complete chromosome number of the parent organism (often being diploid) and is capable of germinating as soon as it encounters favorable conditions, generating an identical individual.
• Aleurospore — An asexual vegetative spore or conidium with a thick wall, produced terminally or laterally directly on the mycelial hyphae of certain microscopic fungi. This spore type develops through the septation of a conidiogenous cell and remains closely attached to the parent hypha until the natural disintegration of the mycelium, ensuring the survival and efficient dissemination of the fungus.
• Amerospore — A type of asexual, unicellular spore of microscopic size, lacking transverse or longitudinal septa, and having a spherical, oval, or elongated shape. This structural element represents the simple propagation unit found in certain species of imperfect fungi (Deuteromycota), morphologically adapted for rapid dissemination in the environment via air currents or water.
• Anerotism — A form of psychological manifestation or constitutional trait characterized by the total absence or marked diminution of erotic and sexual desire, interest, or impulses. Unlike transient pathological manifestations, this bio-structural phenomenon is often integrated into the asexual spectrum, defining the stable way a person interacts emotionally without an erotic component.
• Aplanospore — A non-motile asexual spore, lacking cilia or flagella, provided with its own cell wall that is distinct from the membrane of the mother cell inside which it formed. This structural type of spore is characteristic of certain species of green algae and fungi, being adapted for survival and passive dissemination through air or water currents, unlike motile zoospores.
