#aplanogamet
- Aplanogamete — A sexual reproductive cell (gamete) characterized by the complete absence of cilia or flagella, completely lacking self-motility or independent movement. This structural type of gamete is encountered especially in certain species of green algae and fungi, where dissemination or union with the complementary gamete depends entirely on passive external factors, such as water movement or air currents.
- Aplanogametangium — A unicellular or multicellular reproductive organ (gametangium) within which exclusively aplanogametes (non-motile gametes, lacking cilia or flagella) differentiate and form. This specialized anatomical structure ensures the early protection of non-motile sexual cells during their structural maturation stage, being specific to certain classes of lower plants and primitive fungi.
