Botany

A specialized organ or cell in which gametes are formed in algae, ferns, and some other plants.
〔植〕配子囊
Example sentencesExamples
- Each gametangium yields two morphologically isogamous nonflagellated gametes with anisogamous behavior.
- The sproangia produces mitospores which through mitosis develops into gametangia, or sex organs.
- Both gametangia form from a stereotyped series of divisions of a terminal apical cell, unlike the gametangia of liverworts and hornworts.
- Over four months in culture, the Church Farm worm castings eventually produced populations of four species of Vaucheria (Fig. lb) that we could identify from their gametangia: V. prona, reproductive after 17 d in culture (Fig. 1c); V. frigida, 23 d; V. undulata, 44 d; and V. aversa, 91 d (Table 1).
- When confronted with wild-type mycelia of either sex, some hyperyellow mycelia showed no sexual reactions and others formed a few early structures of the sexual cycle, such as zygophores, but no gametangia or zygospores.

Origin

Late 19th century: from modern Latin gameta (see gamete) + Greek angeion 'vessel' + -ium.
