Diversity in Living Organisms
3,323 Questions
The diversity in living organisms deals with the classification of life forms into various kingdoms and phyla. This topic covers specific traits of bacteria, animal body cavities, and structural adaptations for survival. These fundamentals are crucial for biology sections in medical entrance and state board exams.

Diversity in Living Organisms Questions
-
Virus
-
Fungi
-
Protozoan
-
Bacteria
-
Algae
D
Correct answer
Explanation
Bacteria was the first micro-organism to be discovered.
-
It can be unicellular or multicellular
-
It is larger than viruses
-
It has two major forms
-
It feeds on dead leaves
-
None of these
B
Correct answer
Explanation
Bacteria is larger than viruses. Hence, this option is correct.
-
Algal cells surrounds fungal mesh.
-
Fungal mesh surrounds algal cells.
-
Algal and fungal cells are intertwined.
-
Alga is adhered to the bottom of the fungal cell.
B
Correct answer
Explanation
In lichens, the fungal filaments surround the algal cells.
-
Epinecral layer
-
Pruinia
-
Cephalodia
-
Medulla
C
Correct answer
Explanation
In lichens that include both green algal and cyanobacterial symbionts, the cyanobacteria may be held on the upper or lower surface in small pustules called cephalodia.
-
Amoeba
-
Paramoecium
-
Entamoeba
-
Plasmodium
-
Trypanosoma
E
Correct answer
Explanation
This is the correct option. Trypanosoma is an example of flagellated protozoa.
-
The organisms of this kingdom are multicellular.
-
They depend directly or indirectly on plants for their food.
-
The organisms of this kingdom have cell walls in their cells.
-
Their mode of nutrition is holozoic.
-
The organisms of this kingdom digest food in an internal cavity.
C
Correct answer
Explanation
This is the correct option as this is not a feature of organisms of Kingdom Animalia.
-
Chlamydomonas
-
Chlorella
-
Paramoecium
-
Bacteria
-
Amoeba
D
Correct answer
Explanation
This is the correct option as bacteria is not a member of Kingdom Protista. It is a member of Kingdom Monera.
Amoeba is a member of Kingdom Protista. This is a wrong option.
-
Members of Protista are primarily aquatic.
-
The Protistan cell body contains a well-defined nucleus.
-
All single-celled eukaryotes are placed under Protista.
-
Protists reproduce only asexually.
-
Some have flagella or cilia.
D
Correct answer
Explanation
This is the correct option as this is not a characteristic of kingdom Protista.
-
Methanogens
-
Cyanobacteria
-
Mycoplasma
-
Thermoacidophiles
-
Halophiles
C
Correct answer
Explanation
Mycoplasma are the organisms that completely lack a cell wall, are the smallest living cells known and can survive without oxygen.
Match the following:
|
|
| a. Amoeboid protozoans |
1. They are either free-living or parasitic, having flagella. |
| b. Flagellated protozoans |
2. They live in fresh water, sea water or moist soil. |
| c. Ciliated protozoans |
3. They are aquatic and actively moving organisms as they possess thousands of cilia. |
-
a - 2, b - 3, c - 1
-
a - 3, b - 2, c - 1
-
a - 1, b - 2, c - 3
-
a - 2, b - 1, c - 3
-
a - 3, b - 1, c - 2
D
Correct answer
Explanation
Amoeboid protozoans live in fresh water, sea water or moist soil. Flagellated protozoans are either free-living or parasitic, having flagella. Ciliated protozoans are aquatic and actively moving organisms as they possess thousands of cilia.
-
Many of the bacteria live in or on other organisms as parasites.
-
Bacteria live in extreme habitats, such as hot springs, deserts, snow and deep oceans.
-
Bacteria occur almost everywhere.
-
Their cell wall is made up of cellulose.
-
They are the most abundant microorganisms.
D
Correct answer
Explanation
This is the correct option. Their cell wall is non-cellulosic, and is made of peptidoglycan.
-
The organisms in Kingdom Monera are prokaryotic.
-
The cell wall is non-cellulosic.
-
Nuclear membrane is present.
-
The body organisation is cellular.
-
The modes of nutrition are autotrophic and heterotrophic.
C
Correct answer
Explanation
This is the correct option as this is not a characteristic of Kingdom Monera.
-
Protozoans
-
Slime moulds
-
Euglenoids
-
Chrysophytes
-
Dinoflagellates
A
Correct answer
Explanation
This is the correct option. Protozoans are heterotrophs and live as predators or parasites.
-
Cockroach
-
Amoeba
-
Earthworm
-
Frog
-
All of the above
D
Correct answer
Explanation
Yes, it is correct. Frogs have lungs, just like human beings.
-
They all have segmented genomes.
-
They all are phytophages.
-
They all are DNA viruses.
-
They all are enveloped.
A
Correct answer
Explanation
They all have segmented genomes.
