Weekly Quiz Competition

Question 1
1 / -0

Coenocytic mycelium is

A
uninucleate, septate

B
multinucleate, septate

C
multinucleate, aseptate

D
both (b) and (c)

Solution

Filamentous parasites could contain more than one cores in a coenocytic mycelium. A coenocyte ability as a solitary facilitated unit made out of several cells connected basically and practically, i.E. Through hole intersections. Parasitic mycelia where hyphae need septa are frequently called "aseptate".
So, the correct option is 'multinucleate, aseptate'.
Question 2
1 / -0

Fungi show asexual reproduction by all of the following kinds of spores except

A
conidia

B
oospores

C
sporangiospore

D
zoospores

Solution

Growths indicate agamic multiplication by all the referenced sorts of spores with the exception of oospores(which are sexual spores).
So, the correct option is 'oospores'.
Question 3
1 / -0

The Kingdom Protista forms a link with which of the following kingdom?

A
Plantae

B
Fungi

C
Animalia

D
All of the above

Solution

Kingdom Protista consists of all single-celled eukaryotic organisms. It forms a link with the kingdom Plantae, Animalia and Fungi. It consists of photosynthetic, floating protists called phytoplankton. It also consists of free-floating, holozoic protozoans called zooplankton.
Thus, the correct answer is 'All of the above.'
Question 4
1 / -0

Dikaryophase is a specific characteristic of

A
all Fungi

B
Phycomycetes and Ascomycetes

C
Basidiomycetes and Deuteromycetes

D
Ascomycetes and Basidiomycetes

Solution

In fungi (ascomycetes and basidiomycetes), karyogamy is delayed and occurs just before meiosis. In the stage intervening between plasmogamy and karyogamy, the cells often contain two nuclei or dikaryons (n + n). Such cells are called dikaryotic cells. The phase is known as dikaryophase.
So, the correct option is 'Ascomycetes and Basidiomycetes'.
Question 5
1 / -0

Sexual reproduction in fungi occurs by all of the following except:

A
Basidiospores

B
Ascospores

C
Zoospores

D
Ooospores

Solution

Fungi undergo asexual reproduction by zoospores or aplanospores produced endogenously inside the sporangia. Sexual reproduction is takes place by basidiospores, ascospores, zoospores, and oospores.
So, the correct answer is option C.
Question 6
1 / -0

Genus is a group of similar and related ___________.

A
Classes

B
Phyla

C
Species

D
Orders
Solution
- A genus is a group or assemblage of related species which resemble one another in certain correlated characters.
- Correlated characters are those similar or common features that are used in the delimitation of various taxa.
- The species of one genus differ from species of a related genus in one or more characters.
- All the species of a genus are thought to have evolved from a common ancestor.
Question 7
1 / -0

Bacteria are grouped under four categories according to their shape. Study the given figures and select the correct option regarding this.

A
A - Cocci, B - Bacilli, C - Spirilla, D - Vibrio

B
A - Spirilla, B - Bacilli, C - Vibrio, D - Cocci

C
A - Bacilli, B - Spirilla, C - Vibrio, D - Cocci

D
A - Bacilli, B - Spirilla, C - Cocci, D - Vibrio

Solution

Bacteria are grouped under four categories based on their shape; spherical coccus, the rod-shaped Bacillus, the comma-shaped Vibrium and the spiral Spirillum.
So the correct option is "A-Bacilli, B-Spirilla, C-Vibrio, D-Cocci".
Question 8
1 / -0

Which of the following organisms have been placed under Kingdom Protista?

A
Chrysophytes and dinoflagellates

B
Euglenoids

C
Slime moulds and protozoans

D
All of these

Solution

All single-celled eukaryotes are placed under Protista, but the boundary of this kingdom are not well defined. Protista includes Chrysophytes, Dinoflagellates, Euglenoids, Slime moulds and Protozoans.
So the correct option is "All of these".
Question 9
1 / -0

Select the option that correctly identifies the different genera (A, B, C and D) of Kingdom Fungi shown in figure.

A
A - Mucor, B - Saccharomyces, C - Morchedia, D - Amanita

B
A - Mucor, B - Saccharomyces, C - Penicillium, D - Agaricus

C
A - Rhizopus, B - Sacchaormyces, C - Asperillius, D - Morchella

D
A - Aspergillus, B - Rhizopus, C - Penicillium, D - Agaricus

Solution

The correct option is 'A - Mucor, B - Saccharomyces, C - Penicillium, D - Agaricus'.
Question 10
1 / -0

In Penicillium, the asexual reproduction takes place by

A
ascospores

B
aplanospores

C
sporangiospores

D
conidiospores

Solution

Asexual Reproduction is by a formation of non-motile, produce at the tip of special, asexual spores, hyphae, the conidia, erect called conidiophores.
So, the correct option is 'conidiospores'.
