Diversity in Living Organisms Questions
-
Bacteria
-
Fungi
-
Virus
-
Vectors
C
Correct answer
Explanation
Viruses are considered intermediate because they possess genetic material and can evolve like living organisms, but cannot reproduce independently without host machinery. This unique characteristics places them in a gray area between living and non-living entities. Bacteria and fungi are fully living, while vectors are merely carriers.
-
Large flap like ears
-
Thick layer of fat under the skin
-
A large hump on the body
-
Thick fur over the arctic animals
B
Correct answer
Explanation
Blubber is a specialized thick layer of fat beneath the skin that provides insulation in cold marine environments. It's found in whales, seals, and polar bears. Options A and C describe other adaptive features, while D describes fur rather than fat tissue. Blubber is crucial for thermal regulation in Arctic conditions.
-
Chlamydomonas
-
Chlorella
-
Spirogyra
-
Desmid
C
Correct answer
Explanation
Spirogyra is green algae, which is made of a large number of cylindrical cells, which join together in a chain to form a filament.
-
Green alga
-
Pear-shaped cells
-
Cup-shaped chloroplasts
-
Cell does not have flagella
D
Correct answer
Explanation
Chlamydomonas is a green alga. The top of the cell bears two flagella, used for swimming.
-
Volvox
-
Chlorella
-
Streptococcus
-
Diatoms
B
Correct answer
Explanation
Chlorella contains lots of proteins, fats, vitamins and minerals. For this reason, it is cultivated widely to use as a food supplemented.
-
They are unicellular.
-
They are eukaryote.
-
They can be found in hot springs.
-
They can be found in human intestine.
B
Correct answer
Explanation
Bacteria are unicellular and prokaryotic organisms.
-
Chlamydiomonas
-
Desmid
-
Diatom
-
Volvox
D
Correct answer
Explanation
Volvox is a green, freshwater alga, which lives in colonies in ponds or pools of water.
-
Euglena
-
Giardia
-
Amoeba
-
Paramoecium
A
Correct answer
Explanation
Euglena is an autotropic protozoa, which perform photosynthesis.
-
Giardia
-
Entamoeba
-
Euglena
-
Trypanosoma
C
Correct answer
Explanation
Euglena is an autotropic protozoa, which does not harm the environment.
-
Pseudopodia
-
Flagella
-
Cilia
-
Foot
C
Correct answer
Explanation
Paramoecium swims by beating its cilia against the water.
-
Parasitic
-
Autotrophic
-
Saprophytic
-
All of the above
D
Correct answer
Explanation
There are various forms of Englena. Some are parasitic and some are saprophytic. Certain species are autotrophic.
-
Saprophytic
-
Holozoic
-
Parasitic
-
Autotropic
B
Correct answer
Explanation
Amoeba ingests food, digests it inside the body and excretes the waste out of the body. Thus, it has holozoic mode of nutrition.
-
Diatoms
-
Yeasts
-
Lichens
-
Mushrooms
C
Correct answer
Explanation
Lichens are symbionts as they live in symbiotic relationship with cyanobacteria.
-
Bacteria
-
Fungi
-
Protozoa
-
Viruses
D
Correct answer
Explanation
Viruses are acellular. This means that their body has no cellular substance or nucleus.
-
Saprophytes
-
Parasites
-
Autotrophs
-
Omnivores
B
Correct answer
Explanation
Parasites are organisms that live inside or on another living organism (the host) and obtain nutrients at the host's expense. Examples include tapeworms, malaria parasites, and fungi like athlete's foot. Saprophytes (option A) feed on dead organic matter, autotrophs (option C) make their own food, and omnivores (option D) eat both plants and animals but don't live inside hosts.
