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 symbiotic relation between fungi and the roots of higher plants is called as:
1. | Lichen | 2. | Mycorrhiza |
3. | Amensal | 4. | Proto-cooperation |
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 |
Morels and truffles are edible fungi belonging to the class:
1. | Phycomycetes | 2. | Ascomycetes |
3. | Basidiomycetes | 4. | Deuteromycetes |
Which of the following statements is incorrect?
1. | Yeasts have filamentous bodies with long thread-like hyphae |
2. | Morels and truffles are edible delicacies |
3. | Claviceps is a source of many alkaloids and LSD |
4. | Conidia are produced exogenously and ascopores endogenously |
In a fungus like Neurospora, conidia can be distinguished from ascospores as:
1. | ascospores are diploid, conidia are haploid |
2. | ascospores are produced only by meiosis, conidia are produced only by mitosis |
3. | ascospores have undergone genetic recombination during their production, conidia have not |
4. | ascospores are larger, conidia are smaller |
I: | are called conidia. |
II: | are produced endogenously |
1. | Only I is correct | 2. | Only II is correct |
3. | Both I and II are correct | 4. | Both I and II are incorrect |
I: | Commonly known as sac-fungi |
II: | Mycelium is branched and septate |
III: | The asexual spores are conidia produced exogenously |
1. | Phycomycetes | 2. | Ascomycetes |
3. | Basidiomycetes | 4. | Deuteromycetes |
