'Ergot' is obtained from

  1. Puccinia

  2. Rhizopus

  3. Claviceps

  4. Yeast
Reveal answer Fill a bubble to check yourself
C Correct answer
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
Reveal answer Fill a bubble to check yourself
C Correct answer
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'.

Claviceps purpurea is casual organism of 

  1. Smut of Barley

  2. Rust of Wheat

  3. Ergot of Rye

  4. Powdery Mildew of Pea
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Claviceps purpurea is the fungal pathogen causing ergot disease of rye. It infects rye grains, producing sclerotia containing toxic alkaloids. Smut (Ustilago), rust (Puccinia), and powdery mildew (various fungi) are different plant diseases.

Which saprotroph is similar in appearance to the Mucor?

  1. Penicillium

  2. Neurospora

  3. Rhizopus

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
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.

Which form of sexual reproduction can be related to Mucor?

  1. Isogamy

  2. Anisogamy

  3. Oogamy

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
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 _______.

  1. Hyphae

  2. Mycelium

  3. Spores

  4. Archegonia
Reveal answer Fill a bubble to check yourself
C Correct answer
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'
