Example Sentences

From Project Gutenberg

When the free ends of the hyphae emerge again into the air they swell up into spherical bodies which may either fall off and behave as conidia, each putting out a germ-tube and infecting the host; or the germ-tube itself swells up into a zoosporangium which develops a number of zoospores.

From Project Gutenberg

Each “conidium” contains numerous nuclei and is really a zoosporangium, as after dispersal it breaks up into a number of zoospores.

From Project Gutenberg

Motile zoospores which escape from the zoosporangium are present except in Aplanes.
