  1. Mucor

  2. Aspergillus

  3. Agaricus

  4. Albugo

Show answer
Correct Option: A
Explanation:

Heterothallism was discovered by Blakeslee (1904) in Mucor mucedo.

Which type of life cycle occurs in Mucor?

biology kingdom monera, protista and fungi mycorrhiza classification of fungi useful and harmful microbes

  1. Isomorphic

  2. Heteromorphic

  3. Haplontic

  4. Diplontic

Show answer
Correct Option: C
Explanation:
In Mucor, the haploid stage is multicellular whereas the diploid stage is limited only to the unicellular zygote. The reduction of division or meiosis occurs in zygote.
So the correct answer is option C.

'Ergot' is obtained from

biology kingdom monera, protista and fungi mycorrhiza classification of fungi useful and harmful microbes

  1. Puccinia

  2. Rhizopus

  3. Claviceps

  4. Yeast

Show answer
Correct Option: C
Explanation:
Ergot are the alkaloids obtained from ergot fungi Claviceps purpurea which grow on rye plant. These fungi cause ergot of rye, a fungal disease in plants. The sclerotia of ergot fungi contain alkaloids which are used to produce LSD (Lysergic acid diethylamide) drugs that act on CNS (Central nervous system). They are natural hallucinogens and change mood, behaviour and thoughts like in psychosis, a condition in which thoughts and emotions are affected to such an extent that contact is lost with reality. 
So, the correct answer is 'Claviceps'.

Mucor belongs to .......... sub-division of Eumycota.

  1. Mastigomycotina

  2. Ascomycotina

  3. Zygomycotina

  4. Deuteromycotina

Show answer
Correct Option: C
Explanation:

Zygomycotina is composed of organisms that are characterized by the formation of ribbon-like aseptate hyphae and sexual reproduction with the formation of zygospores. The vast majority of human zygomycotic disease is caused by the members of the family Mucoraceae. This family includes zygomycetes that produce asexual sporangiospores in sporangia. Sporangium producers which may or may not produce stolons and rhizoids and included in the genera Mucor and Rhizomucor. Thus, the correct answer is option 'Zygomycotina'.  

Ergot (of Rye) is obtained from

  1. Claviceps purpurea

  2. Puccinia graminis

  3. Alternaria solanii

  4. Fusarium oxysporum

Show answer
Correct Option: A
Explanation:

Ergot of Rye is a plant disease that is caused by the fungus Claviceps purpurea. The so-called ergot that replaces the grain of the rye is a dark, purplish sclerotium.

Therefore A is correct option. 

Claviceps purpurea is casual organism of

  1. Smut of Barley

  2. Rust of Wheat

  3. Ergot of Rye

  4. Powdery Mildew of Pea

Show answer
Correct Option: C

Which saprotroph is similar in appearance to the Mucor?

biology kingdom monera, protista and fungi mycorrhiza classification of fungi useful and harmful microbes

  1. Penicillium

  2. Neurospora

  3. Rhizopus

  4. None of the above

Show answer
Correct Option: C
Explanation:

Mucor and Rhizopus are fungi belonging to the family Mucoraceae. Mucor is called as pin mould. Rhizopus is known as black mould. They are saprophytic fungi that grow on dead and decaying organic material. The fungal mycelium of Mucor and Rhizopus look like fine cottony threads on the surface of the bread. Thus the correct answer is option C.

Failure of gamentangial fusion in Rhizopus forms _______.

  1. Zygote

  2. Zygospore

  3. Parthenospore

  4. Oidia

Show answer
Correct Option: C

Which form of sexual reproduction can be related to Mucor?

biology kingdom monera, protista and fungi mycorrhiza classification of fungi useful and harmful microbes

  1. Isogamy

  2. Anisogamy

  3. Oogamy

  4. All of the above

Show answer
Correct Option: A
Explanation:

Reproduction in Mucor takes place by isogametes. Mucor reproduces both in the sexual and asexual methods. While asexual reproduction takes place by the formation of spores, sexual reproduction takes place by conjugation of isogamy. 

Hence the correct option is A.

Fungus Rhizopus resembles moss in having _______.

biology kingdom monera, protista and fungi mycorrhiza classification of fungi useful and harmful microbes

  1. Hyphae

  2. Mycelium

  3. Spores

  4. Archegonia

Show answer
Correct Option: C
Explanation:
Rhizopus is a fungus, therefore, non chlorophyllous. It has a saprophytic mode of nutrition. The organism is made of mycelium and produces spores for sexual reproduction.
Moss - Funaria is a Bryophyte, therefore, chlorophyllous, mode of nutrition being autotrophic (photosynthetic). It also produces spores as a result of sexual reproduction.
So, the correct answer is 'Spores'
