A symbiotic relation between fungi and the roots of higher plants is called as:
1. | Lichen | 2. | Mycorrhiza |
3. | Amensal | 4. | Proto-cooperation |
Yeast is unique amongst the members of Kingdom Fungi because it:
1. reproduces by ascospores
2. is unicellular
3. does not have a chitinous cell wall
4. does not have a sexual mode of reproduction
A fungus used extensively in biochemical and genetic work is:
1. | Neurospora | 2. | Trichoderma |
3. | Paecilomyces | 4. | Streptomyces |
Which of the following is not a character of Ascomycetes?
1. | Mycelium is unbranched and septate |
2. | Asexual spores conidia are produced exogenously |
3. | Sexual spores called ascospores are produced endogenously |
4. | Conidia on germination produce mycelium |
The fungus shown in the given diagram can be:
1. Mucor 2. Penicillium 3. Puccinia 4. Ustilago |
Morels and truffles are edible fungi belonging to the class:
1. | Phycomycetes | 2. | Ascomycetes |
3. | Basidiomycetes | 4. | Deuteromycetes |
Given below is a schematic representation of the events in the life cycle of a fungus belonging to Ascomycetes. Identify A-E:
1. | A: Sporangiophore B: Sporangia C: Ascocarp D: 4 Ascospores E: Ascogonium |
2. | A: Sporangiophore B: Sporangia C: Ascocarp D: 8 Ascospores E: Ascogonium |
3. | A: Conidiophore B: Conidia C: Ascogonium D: 4 Ascospores E: Ascocarp |
4. | A: Conidiophore B: Conidia C: Ascogonium D: 8 Ascospores E: Ascocarp |
Ascomycetes and Basidiomycetes have many homologies. All the following will be true but:
1. | Binucleate ascogenous hyphae of ascomyctes and binucleate secondary hyphae of basidiomycetes |
2. | Ascospore and basidiospore |
3. | Hook and crosier method in ascomycetes and clamp connection in basidiomycetes |
4. | Conidia in ascomycetes and basidiomycetes |
