Weekly Quiz Competition

Question 1
1 / -0

Match the following.

A
A-Tobacco mosaic virus, B-coccus, C-Bacillus

B
A-Coccus, B-Bacillus, C-Tobacco mosaic virus

C
A-Bacillus, B-Coccus, C-Tobacco mosaic virus

D
A-Coccus, B-Tobacco mosaic virus, C- Bacillus
Solution
- A coccus is any bacterium that has a spherical, ovoid, or generally round shape. For example, Streptococcus pneumoniae. Hence given diagram (A) represents coccus as they are spherical in shape.
- Bacillus is a genus of Gram-positive, rod-shaped bacteria. For example, Bacillus thuringiensis.Hence given diagram (B) represents Bacillus as they are rod-shaped.
- Tobacco mosaic virus(TMV) is a simple rod-shaped helical virus) consisting of centrally located single-stranded RNA (5.6%) enveloped by a protein coat (94.4%). The protein coat is technically called ‘capsid’. R. Franklin estimated 2,130 sub-units, namely, capsomeres in a complete helical rod and 49 capsomeres on every three turns of the helix; thus there would be about 130 turns per rod of TMV. Hence given diagram (C) represents TMV.
- So, the correct answer is 'A-Coccus, B-Bacillus, C-Tobacco mosaic virus'.
Question 2

Question 3
1 / -0

Match the column-I and column-II
Column-I Column-II
(i) Chrysophyta (a) Fungi
(ii) Gonyaulax (b) Diatom
(iii) Penicillium (c) Plasmodium
(iv) Slime mould (d) Dinoflagellate

A
(i) - a, (ii) - b, (iii) - c, (iv) - d

B
(i) - b, (ii) - c, (iii) - a, (iv) - d

C
(i) - b, (ii) - c, (iii) - d, (iv) - a

D
(i) - b, (ii) - d, (iii) - a, (iv) - c
Solution
- (i)Chrysophyta - (b) Diatom
Chrysophyta is a phylum of unicellular marine or freshwater protists. Members of this phylum include the diatoms (class Bacillariophyta), golden/golden-brown algae (class Chrysophyceae), and yellow-green algae (class Xanthophyceae).
- (ii)Gonyaulax - (d) Dinoflagellate
Gonyaulax is a genus of dinoflagellates with the type species Gonyaulax spinifera Diesing. Gonyaulax belongs to red dinoflagellates and commonly causes red tides.
- (iii)Penicillium - (a)Fungi
Penicillium is a fungus belonging to the division Ascomycetes. It has major importance in the natural environment as well as food and drug production.
- (iv)Slime mould - (c)Plasmodium
There are two main groups of slime moulds in the Protista Kingdom. They are Plasmodial slime moulds or true slime moulds and Cellular slime moulds. Plasmodium slime moulds are a large single-celled mass with thousands of nuclei called a Plasmodium. They are formed when individual flagellated cells swarm together and fuse. The result is one large bag of cytoplasm with many diploid nuclei.
- So, the correct answer is '(i) - b, (ii) - d, (iii) - a, (iv) - c'.
Question 4
1 / -0

Hair-like cilia or whip-like flagella for locomotion and feeding are present in Kingdom:

A
Monera

B
Protista

C
Fungi

D
Plantae

Solution

Organisms belonging to kingdom Protista are unicellular and eukaryotic. Which have a heterotropic or Mixotrophic (Euglena) mode of nutrition.These organisms possess cilia and or flagella for locomotion and or obtaining food.
Example- Paramoecium, chlamydomonas, Euglena etc
So, the correct answer is 'Protista'
Question 5
1 / -0

Factors responsible for the rapid spread of bread mould on slices of bread are:
(i) large number of spores
(ii) availability of moisture and nutrients in bread
(iii) presence of tubular branched hypae
(iv) formation of round shaped sporangia

A
(i) and (iii)

B
(ii) and (iv)

C
(i) and (ii)

D
(iii) and (iv)
Solution
- The sporangium of bread mould releases a large number of spores that germinate on a suitable substratum to form the hyphae.
- Multiple hyphe branch and entangle to form a mat like structure called the mycelium.
- Fungi are saprophytes. Therefore, profuse growth is only possible in presence of a suitable substratum that supplies large amount of moisture and nutrients, like bread.
So, the correct answer is '(i) and (ii)'
Question 6
1 / -0

Which one of the following sets of animals belong to a single taxanomic group ?

A
Cuttlefish, Jellyfish, Silverfish, Dogfish, Starfish

B
Bat, Pigeon, Butterfly

C
Monkey, Chimpanzee, Man

D
Silkworm, Tapeworm, Earthworm

Solution

$$\textbf{Correct option:(C)}$$

$$\textbf{Explanation for correct option:}$$

$$\bullet$$ Monkey, chimpanzee, and man belong to class mammalia. So these three come under a single taxonomic group.

$$\textbf{Explanation for incorrect options:}$$

$$\bullet$$ Cuttlefish belong to phylum mollusca, jellyfish belong to phylum cnidaria, silverfish belong to phylum arthropoda, dogfish belong to superclass pisces in phylum chordata, starfish belong to phylum echinodermata.

$$\bullet$$ Bat belongs to class mammalia, pigeon comes in class aves. Bat and pigeon come under phylum chordata. Where as butterfly comes in class insecta of phylum arthropoda.

$$\bullet$$ Silkworm belongs to phylum arthropoda, tapeworm to phylum platyhelminthes, and earthworm to phylum annelida.
Question 7
1 / -0

Contagium vivum fluidum was proposed by-

A
D.J. Ivanowsky

B
M.W. Beijerinek

C
Stanley

D
Robert Hook

Solution

$$\textbf{Correct option:(B)}$$

$$\textbf{Explanation for correct option:}$$

$$\bullet$$ M.W. Beijerinek (1898) demonstrated that the extract of infected plant of tobacco could cause infection in healthy plants and called the fluid "Contagium vivum fluidum".

$$\bullet$$ "Contagium vivum fluidum" (Latin: "contagious living fluid") was a phrase first used to describe a virus.

$$\bullet$$ Hence, the correct answer is (B)
Question 8
1 / -0

Which of the following reproduces by spores?

A
Fungi

B
Virus

C
Amoeba

D
Hydra

Solution

Almost all fungi reproduce asexually by producing spores. A fungal spore is a haploid cell produced by mitosis from a haploid parent cell. It is genetically identical to the parent cell. Fungal spores can develop into new haploid individuals without being fertilized.
Thus, the correct answer is option A.
Question 9
1 / -0

Study the following characteristics about bacteria and select the correct answer.
1) Bacterial structure is very simple because they are unicellular and prokaryotic.
2) Bacteria as a group show most extensive metabolic activity.
3) Based on shape bacteria are grouped into two categories.
4) Most bacteria do not have cell wall.

A
1 and 2 are correct, 3 and 4 are incorrect.

B
3 and 4 are correct, 1 and 2 are incorrect.

C
1 and 4 are correct, 2 and 3 are incorrect.

D
2 and 3 are correct, 1 and 4 are incorrect.

Solution

Bacteria belong to Kingdom Monera of the 5 kingdom classification. The kingdom includes unicellular prokaryotes, the bacteria.
They are classified into four groups based on their shape namely, Coccus, Bacillus, Spirillum and Vibrio.
They are characterised by the presence of cell wall and exhibit a variety of metabolic activity due to their diverse modes of nutrition intake.
So, the correct answer is '1 and 2 are correct, 3 and 4 are incorrect.'
Question 10
1 / -0

Identify the fake moss.

A
Polytrichum

B
Sphagnum

C
Cladonia

D
