The fungi are classified based on the characteristics of the sexual spores and fruiting bodies present during the sexual stages of their life cycles. Therefore, based on characteristics of their sexual stages and morphology of their asexual spores and thalli they are classified into different groups.
What is Fungi? Definition of Fungi Fungi are eukaryotic organisms that include yeasts, molds, and mushrooms. They are heterotrophic, meaning they obtain nutrients by absorbing dissolved molecules from their surroundings, and they play a vital role in decomposing organic matter. Fungi are classified in the kingdom Fungi and are distinct from plants, animals, and bacteria, … Read more
What are Actinomycetes? Actinomycetes are a diverse group of Gram-positive, catalase-positive, nonmotile bacilli that exhibit characteristics bridging bacteria and fungi. Structurally, they resemble bacteria due to their cell walls containing muramic acid and prokaryotic nuclei, making them susceptible to antibiotics. However, their filamentous growth pattern, forming structures known as hyphae, is reminiscent of fungi. These … Read more
