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 |
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 |
What is not true regarding sexual reproduction in basidiomycetes?
| 1. | Sex organs are well developed |
| 2. | Plasmogamy is brought about by fusion of two vegetative or somatic cells of different strains or genotypes |
| 3. | Karyogamy and meiosis take place in basidium, producing four basidiospores |
| 4. | Basidiospores are produced exogenously on the basidium |
Rusts and Smuts are the fungi that belong to:
| 1. | Phycomycetes | 2. | Ascomycetes |
| 3. | Basidiomycetes | 4. | Deuteromycetes |
Which of the following is not a feature of the members of the class Basidiomycetes?
1. Branched and septate mycelium
2. Asexual spores are generally not formed
3. Vegetative reproduction not seen
4. Dikaryon stage commonly seen
| Statement I: | A is karyogamy; B is plasmogamy and C is meiosis. |
| Statement II: | Though not shown in the figure the fungi belonging to this class reproduced extensively by asexual methods involving conidia. |
