Meaning and Definition
A non-motile gamete; a reproductive cell (e.g., an egg or sperm cell) that lacks the ability to move independently.
In botany and mycology, specifically refers to the type of gamete involved in certain forms of sexual reproduction in algae, fungi, and some plants where the male gamete is not flagellated and relies on other means (e.g., water currents, direct contact) for fertilization.

Common Mistakes When Using “aplanogamete”
- Misspelling as 'aplanagamete' or 'aplanogamate'.
- Using it as a general term for any spore or cell.
- Confusing it with 'isogamete' (a gamete of similar size). Motility, not size, is the defining feature.
FAQ
Frequently Asked Questions
No. While in many organisms (like animals) the non-motile gamete is the egg (female), the term 'aplanogamete' is defined by motility, not sex. In some isogamous species, both fusing gametes may be aplanogametes.
The egg cell (ovum) of animals is technically an aplanogamete—it is non-motile. However, the term is almost never used in zoology; it is standard in botany and mycology.
The direct opposite is a planogamete or zoogamete, which is a motile, usually flagellated gamete like the sperm of many animals, algae, and lower plants.
It is a highly specific technical term from a narrow field of biology. Most general biological discourse uses more common terms like 'non-motile gamete', 'egg cell', or 'sperm cell' depending on the context.
