#asexual spore

• 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.
• Autospore — A type of non-motile, asexual spore produced within the parental cell wall in certain species of unicellular green algae (such as the genus Chlorella). The autospore is a perfect, fully formed microscopic replica of the mother cell, possessing the same cellular framework and its own membrane before being released via the rupture of the outer protective wall.
