zygospore

zygospore

/ zī′gə-spôr′,zĭg′ə- /

A large, multinucleate spore formed by union of isogametes (gametes that are not distinguished by size and structure), as in certain algae or fungi. A zygospore develops thick, resistant walls and enters a period of dormancy before germinating.

zy·go·spor·ic [zahy-g, uh, -, spawr, -ik, -, spor, -, zig-, uh, -], adjective

First recorded in 1860–65; zygo- + -spore

The zygospore thus formed germinates after a long period and forms a new filament of cells.

During all these changes, while the zygospore enlarges, the wall of the arcuate cells becomes coloured brown.

The product of the union of two zygoblasts is termed a zygospore.
