Question 1
1 / -0

An organism that decomposes dead remains is most likely to utilize which of the following modes of nutrition?

A
Parasitic

B
Saprophytic

C
Autotrophic

D
All of the above

Solution

Saprophytes are the organism that derive their food from dead and decaying organic matter. The saprophytes can be obligate or facultative. They decompose the remains plant and animal material.
So, the correct answer is option B.
Question 2
1 / -0

A fungal spore

A
Contains an embryonic organism

B
Germinates directly into an organism

C
Is always windblown

D
Both (b) and (c)

Solution

The phylum fungi produce spores as a method of asexual reproduction.
The fungal spores results in the formation of an entire organism. It contains an embryonic organism which germinates directly into a new fungal organism.
So, the correct answer is option D.
Question 3
1 / -0

Which one of the following features is not associated with Rhizopus?

A
Zoospores

B
Columella

C
Sporangiophore

D
Filamentous hyphae

Solution

Zoospores are motile spores, usually formed in Algae and other plant forms. In fungi zoospores are absent. Rhizopus belong to Phycomycetes, where the hyphae are filamentous, coenocytic and reproduce asexually by formation of sporangiospores in the sporangia. Sporangia are club like structures formed at the tip of erect hyphae. The entire content of the hyphae moves into the buldged tip and is sealed or separated by the rest of the hyphae by a sterile region called the columella

So, the correct answer 'Zoospores'
Question 4
1 / -0

Which of the following groups consist of organisms that multiply by fragmentation?

A
Earthworm, Amoeba, fungi

B
Earthworm, fungi, bacteria

C
Fungi, filamentous algae, protonema of mosses

D
Amoeba, Hydra, bacteria
Solution
- In fungi, vegetative reproduction occurs by fragmentation or budding (in yeasts).
- In algae, asexual reproduction occurs by means of various kinds of spores. However, in some filamentous algae, multiplication occurs by fragmentation.
- In Bryopsida (mosses), vegetative reproduction occurs through fragmentation, formation of secondary protonenia, gemmae, tubers, etc.
  So the correct option is C.
Question 5
1 / -0

Thermococcus, Methanococcus and Methanobacterium exemplify

A
Bacteria that contain a cytoskeleton and ribosomes

B
Archaebacteria that contain protein homologous to eukaryotic core histones

C
Archaebacteria that lack any histones resembling those found in eukaryotes but whose DNA is negatively supercoiled

D
Bacteria whose DNA is relaxed or positively supercoiled but which have a cytoskeleton as well as mitochondria

Solution

Thermococcus, Methanococcus and Methanobacterium are archaea whose histones are shorter than eukaryotic histones and are assembled in tetramers.
So the correct answer is' Archaebacteria that contain protein homologous to eukaryotic core histones'
Question 6
1 / -0

In Whittaker's five kingdom system of classification, eukaryotes are distributed among

A
Two kingdoms

B
Three kingdoms

C
Four kingdoms

D
All the five kingdoms
Solution
Correct Option: C
Explanation:
- Whittaker gave the five-kingdom classification which was based on the cell structure, body organization, mode of nutrition and reproduction, and phylogenetic relationships.
- The kingdoms include Monera, Protists, Fungi, Plantae, and Animalia.
- Monerans are prokaryotic and Except it, rest all four are eukaryotic in nature.
Hence, the Four kingdoms are eukaryotic.
Question 7
1 / -0

Choose the correct answers from the alternatives given .
Which of the following living phenomenon is absent in viruses?

A
Mutation

B
Replication

C
Production of energy

D
None of these

Solution

As viruses are not cells and have no activity within it, it has no need for production of energy. But they mutate and replicate.
So, the correct option is 'Production of energy'.
Question 8
1 / -0

Which of the following statements is incorrect regarding the modern taxonomy?

A
It deals with biological species

B
It is based on the study of all types of variations in the species

C
Species are considered to be static

D
It has a bio-systematics concept

Solution

In modern taxonomy, species is considered to be dynamic.
Correct answer is option C.
Question 9
1 / -0

Artificial systems of classification were based on

A
Vegetative characters

B
Androecium structure

C
All of these

D
None of these

Solution

Artificial systems of classification were based on morphological characters such as habit, habitat, colour, number and shape of leaves. They were mainly based on vegetative characters or on the androecium structure.
So, the correct answer is 'All of these'.
Question 10
1 / -0

The virus which replicates in an arthropod, the intermediate host, and then goes to its permanent host, the vertebrates, is called

A
Reovirus

B
Arbovirus

C
Papoavirus

D
Parvovirus
Solution
Reoviruses have genomes consisting of double-stranded RNA which exists in the host cells in a monopartite and non-tubule guided viral movement.
Existing in occlusion bodies after cell death and remaining infectious until finding another host is their speciality.
So, the correct option is 'Reovirus'.
