Question

how do pythium's reproduction ?

Answer 1

Asexual reproduction takes place by the formation of sporangia. Sporangia may be or intercalary in position and are produced on the aerial hyphae. There are no specialised sporangiophores to produce sporangia. The terminal or intercalary position of a hypha enlarges and becomes spherical and starts off function as sporangial initial.

It gets cut off from rest of the mycelium by a transverse septum. Sporangia are multinucleate and may be filamentous, tubular or globes in shape. Sporangia germinate indirectly or directly. Indirect germination. Under favourable conditions (high humidity) sporangia behave as zoosporangia. And produce zoospores. Sporangium germinates by germ tube or by forming a hypha. Both terminate into a thin walled vesicle.
