Penicillin, abbreviated as PCN or pen, is a group of antibiotics that resulted from Penicillium fungi. produce sporangiospores d. Conidia are one of the two types of asexual reproduction of fungi, since there are also other asexual spores that are internal and immobile and that are formed within a specialized structure -sack-shaped- known as a sporangium, which is supported by another accessory structure called the sporangiophore. A mature sporangium of a Mucor fungus. The conidiosporesof Penicillium(see Fig. You often see this fungus growing on stale bread and cheese. However, the cell wall material of fungi is completely different from that of plants. Crozier formation is a characteristic feature of . Mycelium is branched and septate. They too are made by mitosis. The conidia of these fungi not only germinate and produce a new generation, they also function in dispersal and so have .

Which among the following is the true statement? Some species of Penicillium reproduce sexually by means of asci and ascospores produced within small stony stromata. Penicillium is a genus of ascomycetous fungi of major importance in the natural environment as well as food and drug production.. Members of the genus produce penicillin, a molecule that is used as an antibiotic, which kills or stops the growth of certain kinds of bacteria inside the body. Examine the deuteromycete Penicillium. It is the source of the antibiotic penicillin. Penicillium spp. So, the correct answer is option B. an asexual spore formed at the tip of a specialized hypha (conidiophore) in fungi such as Penicillium. : penicillus). Fungi move into new food sources by growing or by the passive dispersal of nonmotile spores. {After Falck, 1916.). Mycelium with conidiophore and conidium isolated on white background sporangium stock illustrations. Sterigmata - a specialized structure that arises from a basidium and supports basidiospores 34. Chains of conidia are present terminally, which gives it a brush like appearance. 2. In the fungi that reproduce sexuallywe call the spore-producing structure a fruiting body(like a mushroom), or in the case of the Zygote fungi it is also called a sporangium. MCQ on Penicillium: Biology is one of the most important and vital sections in NEET.It includes theories, descriptions, discoveries, diagrams, definitions, explanation of differences and relations. This organism typifies the confusion that can arise in fungal taxonomy. When they alight on a favourable medium, they germinate a network of hyphae (threads), the function of which is to absorb food for growth & spore production. 15.
