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

Multiple choice

Yeast belongs to

  1. Animalia

  2. Plantae

  3. Monera

  4. Protista
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Yeast is a unicellular fungus. In the Whittaker five-kingdom system, all unicellular eukaryotic organisms are placed in the kingdom Protista.

Multiple choice

Golden Algae are included in

  1. Chrysophytes

  2. Dinoflagellates

  3. Protozoa

  4. Slime moukds
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Golden algae are included in Chrysophytes. The name 'chrysophyte' comes from Greek 'chrysos' meaning gold, referring to the golden color of these algae due to accessory pigments. Dinoflagellates have different pigments, protozoa are heterotrophs, and 'slime moukds' is a misspelling.

Multiple choice

Protista includes

  1. Unicellular

  2. Eukaryotes

  3. Both

  4. None
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The kingdom Protista consists of organisms that are eukaryotic and primarily unicellular. Therefore, it includes both characteristics.

Multiple choice

Jokers of Plant Kingdom

  1. Eubacteria

  2. Archaebacteria

  3. Mycoplasma

  4. None
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Mycoplasma are often called the jokers of the plant kingdom because they lack a cell wall and can change their shape, making them pleomorphic.

Multiple choice

Cell Wall is absent in

  1. Archaebacteria

  2. Eubacteria

  3. Mycoplasma

  4. All
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Mycoplasma are unique among prokaryotes because they completely lack a cell wall, which makes them resistant to many antibiotics that target cell wall synthesis.

Multiple choice

PPLO is

  1. Archaebacteria

  2. Mycoplasma

  3. Eubacteria

  4. None
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

PPLO stands for Pleuropneumonia-like organisms, which is another name for Mycoplasma.

Multiple choice

Monera inudes

  1. Archaebacteria

  2. Eubacteria

  3. Mycoplasma

  4. All
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Monera (kingdom of prokaryotes) includes all prokaryotic organisms: Archaebacteria (ancient bacteria), Eubacteria (true bacteria), and Mycoplasma (wall-less bacteria grouped under eubacteria in modern classification). Since all are prokaryotes belonging to Monera, option D 'All' is correct.

Multiple choice

Peptidoglycan is present in Cell Wall of

  1. Archaebacteria

  2. EuBacteria

  3. Mycoplasma

  4. All
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Peptidoglycan is a characteristic component of the cell wall in Eubacteria (true bacteria). Archaebacteria have different cell wall compositions, and Mycoplasma lack a cell wall entirely.

Multiple choice

Monera includes

  1. Prokaryotes

  2. Unicelluar

  3. Both

  4. None
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Members of the kingdom Monera are defined as being both unicellular and prokaryotic.

Multiple choice

Bacteria belong to

  1. Animalia

  2. Plantae

  3. Protista

  4. Monera
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Bacteria are prokaryotic organisms and are classified under the kingdom Monera in the five-kingdom classification system.

Multiple choice

Virus belongs to

  1. Plantae

  2. Monera

  3. Protista

  4. None
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Viruses are considered acellular entities that do not fit into the five-kingdom classification system because they lack independent metabolic processes.

Multiple choice

Which is not a type of microbe?

  1. Bacteria

  2. Virus

  3. Fungi

  4. Euglena

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Euglena is a genus of single-celled eukaryotic organisms, specifically a protist, not a microbe in the context of typical disease-causing pathogens like bacteria or viruses. While microscopic, it is classified differently than the others.
