Include a schematic diagram for easy understanding.Give outline classification of fungi as per G.M.Smith upto classes giving example of each class.Complete the table below. Characteristics TYPES OF SPORES Crosswalls in hyphae PHYLUM Asexual sexual (present or absent) short description Zygomycota Ascomycota Basidiomycota
- Complete the following table distinguishing the true fungi phyla based on reproduction. SEXUAL reproduction through conjugation of 2 different mating strains ASEXUAL reproduction by conidial ASEXUAL reproduction by spores (produced in sporangia) ASEXUAL reproduction by conidia (produced on tips of conidiophores) or budding Do not perform SEXUAL reproduction. SEXUAL reproduction by fusion of 2 mating types of monokaryotic hyphae. Resulting dikaryotic mycelium often develops basidiomata SEXUAL reproduction through the union of male and female structures, followed by formation of asci ASEXUAL reproduction by zoospores (produced in zoosporangia) ASEXUAL reproduction is rare, but can occur by conidia.
