Cylindrical zoosporangia develop at the tips of hyphae which produce numerous biflagellate zoospores. When mature, they can be seen jostling one another within the zoosporangium. The apex of the zoosporangium suddenly breaks […]

Mycorrhizas (sing, mycorrhiza), discovered by the German botanist, Frank in 1885, are structures formed by association of fungi and roots of plants. Mycorrhizas are classified into three categories- ectotophic, endotrophic and ectendotrophic. In ectotrophic mycorrhiza, the fungus forms a mantle or hyphal sheath […]
