Q. No.The imperfect fungi which are decomposers of litter and help in mineral cycling belong to
1. Deuteromycetes
2. Basidiomycetes
3. Phycomycetes
4. Ascomycetes
Fungi imperfecti constitute a group that
1. are obligatory parasites
2. reproduce only asexually
3. do not cause disease in humans
4. resemble bacteria in some respects
Deuteromycetes are known as ‘imperfect fungi’ because –
| 1. | Only the sexual phases of these fungi are known. |
| 2. | Because they do not have true cell wall |
| 3. | Only the asexual or vegetative phases of these fungi are known. |
| 4. | They do not show typical fungal characteristics. |
On the discovery of sexual phase in a fungus the mycologist moved it from class ‘A’ to ascomycetes. Identify the class ‘A’?
| 1. | Phycomycetes | 2. | Basidiomycetes |
| 3. | Ascomycetes | 4. | Deuteromycetes |
Which type of spores are found in the members of deuteromycetes?
| 1. | Zoospore | 2. | Aplanospore |
| 3. | Conidia | 4. | Oospore |
Which one of the following matches is correct?
| (a) | Phytophthora | Aseptate Mycelium | Basidiomycetes |
| (b) | Alternaria | Sexual reproduction Absent | Deuteromycetes |
| (c) | Mucor | Reproduction by conjugation | Ascomycetes |
| (d) | Agaricus | Parasitic fungus | Basidiomycetes |
2. (b)
3. (c)
4. (d)
An artificial group within fungi is
1. Ascomycetes
2. Deuteromycetes
3. Basidiomycetes
4. Phycomycetes
Which of the following is correct about class Deuteromycetes?
1. Some members are saprophytes or parasites.
2. A large number of members are decomposers of litter and help in mineral cycling.
3. Alternaria, Colletotrichum and Trichoderma are deuteromycetes.
4. All
Which of the following statement is correct for Deuteromycetes?
| 1. | A large number of them are decomposers of litter, but do not help in mineral cycling |
| 2. | Mycelium is septate and branched |
| 3. | They may have three names, one for vegetative stage and two for asexual stage |
| 4. | Common asexual spore is oidia |
Find the odd one with respect to the fungi imperfecti
1. Alternaria
2. Colletotrichum
3. Trichoderma
4. Penicillium
