noun
zoospore
A motile asexual spore that uses a flagellum for locomotion, found in certain algae, fungi, and protozoa. Technical term used in biology.
藻類の遊走子は鞭毛を使って水中を移動する。
The zoospores of algae move through water using flagella.
遊走子のうから遊走子が放出される。
Zoospores are released from the zoosporangium.
遊走子のう is the zoosporangium, the structure that produces and contains zoospores.
Compound of 遊走 (yūsō, 'moving freely') + 子 (shi, 'spore' or 'offspring'). The term is a direct calque from the English 'zoospore' (zoo- 'animal' + spore), reflecting the spore's animal-like motility.
