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
The phenomenon of red tides is associated with blooms of:
1. | Zooxanthelle | 2. | Gonyaulax |
3. | Blue green algae | 4. | Ctenoplana and Beroe |
Identify the incorrect statement regarding Euglenoids:
1. | Majority are found in fresh stagnant water |
2. | Presence of two flagella |
3. | Behave as heterotrophs when deprived of sunlight |
4. | Pigments entirely different from those found in higher plants |
The commercial production of citric acid is possible with the help of:
1. Xanthomanascitri
2. Claviceps purpura
3. Trichodermaharzianum
4. Aspergillus niger
Which of the following is not true for fungi belonging to the class phycomycetes?
1. | Aseptate and coenocytic mycelium |
2. | Spores endogenously produced in sporangium |
3. | Asexual reproduction by nonmotile zoospores or motile aplanospores |
4. | Found in aquatic habitats, decaying wood or as obligate parasites on plants |
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 |

The saprophytic protists are:
1. | Slime moulds | 2. | Protozoans |
3. | Desmids | 4. | Dinoflagellates |
Rusts and Smuts are the fungi that belong to:
1. | Phycomycetes | 2. | Ascomycetes |
3. | Basidiomycetes | 4. | Deuteromycetes |
Which protists are all heterotrophs and live as predators or parasites?
1. | Desmids | 2. | Slime moulds |
3. | Protozoans | 4. | Euglenoids |
The major criteria used for classification of Protozoans is:
1. | Nature of cell envelope | 2. | Mode of locomotion |
3. | Mode of heterotrophic nutrition | 4. | Habitat |
