Summary Introduction
Reproduction process in
Sexual spores are developed by the process known as fusion, in which two gametes of opposite sex are fused to form sexual spore. The cell which bears the gamete is known as gametangium. In sexual spore, meiosis takes place.
Conidia are produced on special hyphae called conidiophores and help in the germination of new fungal cells.
