Weekly Quiz Competition

Question 1
1 / -0

Which one of the following does not belong to monera?

A
Slime moulds

B
Mycoplasma

C
Eubacteria

D
Archaebacteria

Solution

Monera is one of the kingdom. It contains unicellular prokaryotic organisms. They lack true nucleus and cell membrane. Bacteria belongs to this kingdom. Apart from bacteria, Eubacteria, Cyanobacteria, Archaebacteria and mycoplasma belong to this kingdom. Slime mould belongs to Kingdom Protista.
Thus, the correct answer is option A.
Question 2
1 / -0

Thread-like fungal structures are known as__________.

A
Hyphae

B
Mycelium

C
Both A and B

D
None of the above

Solution

Except for yeasts, which grow as single cells, most fungi grow as thread-like filaments known as hyphae. Each hypha consists of one or more cells surrounded by a tubular cell wall.
Therefore A is the correct option.
Question 3
1 / -0

Lichens show symbiotic relationships between

A
Fungus and roots of higher plants

B
Fungus and alga

C
Two algae

D
Two fungi

Solution

A lichen is a composite organism that arises from algae or cyanobacteria (or both) living among filaments of a fungus in a symbiotic relationship. The combined life form has properties that are very different from the properties of its component organisms. The fungus benefits from the symbiotic relation because algae or cyanobacteria produce food by photosynthesis. The algae or cyanobacteria benefit by being protected from the environment by the filaments of the fungus, which also gather moisture and nutrients from the environment, and (usually) provide an anchor to it.
Thus, the correct answer is option B.
Question 4
1 / -0

Which of the following statement is wrong about lichens?

A
Some species are eaten by Reindeers.

B
Lichens are indicators of pollution.

C
They grow rapidly about 2 cm per day.

D
They have symbiotic relationship between alga and fungus.
Question 5
1 / -0

Conidia of Albugo are arranged

A
Irregularly

B
Acropetally

C
Basipetally

D
Intercalary
Question 6
1 / -0

Zoospore of Albugo possesses .......... flagella.

A
Two similar and apical

B
Two similar and median

C
Four apical

D
Two dissimilar and lateral
Question 7
1 / -0

Common bread mould is

A
Yeast

B
Rhizopus

C
Clostridium

D
Myxovirus

Solution

Rhizopus stolonifer is commonly known as black bread mold. It is a member of Zygomycota and considered the most important species in the genus Rhizopus. It is one of the most common fungi in the world and has a global distribution although it is most commonly found in tropical and subtropical regions.
Question 8
1 / -0

Majority of lichens are made of

A
Blue-green algae and basidiomycetes

B
Blue-green algae and ascomycetes

C
Red algae and ascomycetes

D
Brown algae and higher plants
Solution
- Lichens are a complex life form that is a symbiotic partnership of two separate organisms, a fungus, and an alga. Usually the association is between member of Ascomycetes with Cyanobacteria. However, in certain cases the association is established between member of Basidiomycetes and Cyanobacteria or chlorophyceae.
- So, the correct answer is "Blue-green algae and ascomycetes'.
Question 9
1 / -0

Fertilization does not require water in

A
Ulothrix

B
Albugo

C
Bryophyta

D
Pteridophyta

Solution
Question 10
1 / -0

Symbiotic association of fungi and algae is

A
Lichen

B
Mycorrhiza

C
Mycoplasma

D
Both A and B

Solution

A lichen is a long living composite organism that arises from green algae or cyanobacteria living among filaments of a fungus in a mutually beneficial relationship (symbiotic relationship). The algal component of a lichen is known as phycobiont and the fungal component is called mycobiont.
Example, Usnea
So, the correct answer is 'Lichen'
