To enhance clearing dimethyl sulfoxide can be added to the slide. Coming in contact with the oogonium, the antheridium passes its nucleus inside the oogonium through fertilisation tube and forms oospore. Using reduced examine the smear microscopically (100X) for the presence of encapsulated cells as indicated by clear zones surrounding the cells. Further dilution with water is not recommended. 4. Spore Forms in Fungi: Fungi reproduce both asexually and sexual­ly by different types of spores. These are oospores, zygospores, ascospores and basidiospores: These are diploid (2n) spores formed by the union between egg and male nucleus. Fruiting bodies are modified hyphae that make asexual spores. Includes mushrooms, toadstools, puffballs, bracket fungi, shelf fungi, stinkhorns, rusts, and smuts, 3. Release digestive enzymes to break down organic material or their host. Fungi reproduce sexually when environmental conditions are unfavorable. Shop for Best Price Warriors Don T Cry Multiple Choice Test And Fungi Multiple Choice Questions And Answers Pdf . Hyphae without septa are called coenocytic hyphae. When these grains are eaten by humans or when they are fed to dairy cattle and they get into the milk supply, they affect humans. Thus generally a chain of conidia are deve­loped, where younger one always remains near the mother, e.g., Tricho- derma, Fusarium. All hyphae within a mycelium share the same cytoplasm so materials move quickly. Some show the presence of spores formed directly from the hyphae (arthroconidia). The most common pathogenic species are Aspergillus fumigatus and Aspergillus flavus. They develop from a bottle-shaped cell, the phialide. The male organ is called antheridium while the female one is known as, Question 23 : The rusts are serious diseases of our economic plants. Most fungi reproduce asexually by spores. Questions and Answers # 8. Questions and Answers # 2. Infection is usually due to inhaling contaminated air. It struck down the plants like frost in the summer. Penicillium mold produces spores called conidia without a protective sac on the top of a stalk called the conidiophore. A fungus culture is usually acquired from wound exudates and swabs of areas that are within the body like the mouth and vagina. It is a resting spore, e.g., members of Oomycetes under Mastigomycotina. During the 1860s, great waves of Irish immigrants came to the United States. 3.

Question 36 : Which of the following is not a fungus? Athlete’s foot fungus reproduces by fragmentation from a small piece of mycelium. 6. In majority of the members of Mastigo­mycotina and Zygomycotina, the sexually produced spores are developed freely and are not surrounded by sterile hyphae. 2. The spores formed after sexual reproduction are the sexual spores. They can develop from a cell of an undifferentiated hypha or conidiophore at o ;e or more points through budding, either apically or late­rally. 2.

Asexual reproductive structure called sporangium and produces sporangiospores. 6. Questions and Answers # 3.
