A symbiotic relation between fungi and the roots of higher plants is called as:
1. | Lichen | 2. | Mycorrhiza |
3. | Amensal | 4. | Proto-cooperation |
Column I | Column II | ||
A | Ascomycetes | P | Club-shaped reproductive structure |
B | Basidiomycetes | Q | Sexual spores borne internally in sacs |
C | Phycomycetes | R | Includes Mucor and Rhizopus |
D | Deuteromycetes | S | Known for lacking sexual reproduction |
A | B | C | D | |
1. | Q | R | S | P |
2. | P | Q | R | S |
3. | Q | P | R | S |
4. | S | P | Q | R |
Alternaria, Colletotrichum and Trichoderma belong to the class:
1. | Phycomycetes | 2. | Ascomycetes |
3. | Basidiomycetes | 4. | Deuteromycetes |
Deuteromycetes are also called as Fungi imperfecti because:
1. They do not have a thalloid body
2. They can contain chlorophyll
3. There are no parasitic members
4. Sexual phases are not known
Which of the following is not true regarding members of Dueteromycetes?
1. | Mycelium is septate and branched. |
2. | Many are decomposers and help in mineral cycling. |
3. | They reproduce only by asexual spores called as conidia. |
4. | They include Agaricus, Claviceps and Colletotrichum. |
Assertion (A): | Alternaria, Colletotrichum and Trichoderma are kept in the fungal class- deuteromycetes. |
Reason (R): | Asexual and vegetative phases in the life cycle of these fungi are not known. |
1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
3. | (A) is True but (R) is False. |
4. | Both (A) and (R) are False. |
The imperfect fungi which are decomposer of litter and help in mineral cycling belong to:
1. | Basidiomycetes | 2. | Phycomycetes |
3. | Ascomycetes | 4. | Deuteromycetes |
I: | Sexual phases are yet to be discovered. |
II: | The asexual and vegetative stage have been given one name (and placed under deuteromycetes) and the sexual stage another (and placed under another class). |
