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 biology biodiversity and classification animal classification and its benefits criteria for new system of classification five kingdoms of living organisms

Kingdom Animalia are classified into

  1. Phylum Porifera

  2. Phylum Arthropoda

  3. Phylum Chordata

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

Kingdom Animalia is classified into 36 phyla on the basis of similarity and dissimilarity. Phyla are further divided into the class.
Phylum Porifera belongs to the animal kingdom which has the cellular level of organization.
Phylum of the animal kingdom which has tissue level of organization are Arthropoda, Platyhelminthes, Nematoda, Cnidaria, Annelida, Echinodermata, Mollusca and Chordata.
Thus, the correct answer is option D.

An organisms lacks complete digestive tract is

I. Jellyfish
II. Mollusk
III. Earthworm

  1. I, II and III

  2. I only

  3. II only

  4. III only

  5. I and III only
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Jellyfish have an incomplete digestive system as the same orifice is used for both food intake and waste expulsion. Mollusk and earthworm have a complete digestive system with distinct openings for food intake and waste expulsion. 

Therefore, the correct answer is option B.

For the data table shown above, a 1 indicated that the trait is present and a 0 indicates that the trait is absent.
Which of the following statements represents an accurate interpretation of the data?

  1. All organisms in the table share all of the derived characteristics.

  2. Only humans and gorillas share all of the derived characteristics.

  3. Because it shares none of the derived characteristics, lampreys constitute an out-group.

  4. Because it shares just one of the derived characteristics, sharks can be considered an internal branch of the phylogenetic tree.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

From the table, it is seen that except Lamprey, all organisms share derived characteristics. Because it shares none of the derived characteristics, it constitute an out-group. Humans and gorillas share most of the derived characteristics. Because it shares just one of the derived characteristics, sharks can be considered an outer most branch of the phylogenetic tree.

Thus, the correct answer is 'Because it shares none of the derived characteristics, lampreys constitute an out-group.'

Maximum nutritional diversity is found in the group _________.

  1. Fungi

  2. Animalia

  3. Monera

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

Fungi take their nutrition by absorbing organic compounds from the surrounding environment. Monera kingdom contains unicellular prokaryotic organism. Kingdom Plantae consists of multicellular photosynthetic eukaryotes. Kingdom Animalia has multicellular eukaryotic  organisms which consume organic matter and hence maximum nutritional diversity is found in this group.

The correct answer is B.

Animals with self fertilization is

  1. Paragonimus

  2. Dugesia

  3. Taenia solium

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

In Taenia solium both self-fertilization and cross-fertilization occur. In self-fertilization, sperms produced in proglottid fertilize the ova produced in the same proglottid. In cross-fertilization, sperms produced in a proglottid fertilize ova produced in another mature proglottid of the same worm. In paragonimus and dugesia self-fertilization is absent.

Which of the following worms are categorized as thread worms?

  1. Tapeworm

  2. Earthworm

  3. Roundworm

  4. None of the above

C Correct answer
Explanation

Threadworms are a type of roundworms.

Common characteristics of roundworms that confirm this are:
1. First organisms with organ level classification
2. They are often parasitic
3. Triploblastic
4. Bilaterally symmetrical

Which of the following animal phylum includes segmented worms?

  1. Annelida

  2. Arthropoda

  3. Mollusca

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Molluscs do not have segmentation in their bodies.

Arthropoda has segmentation as a character but it does not include worms.
Annelids is the phylum of the segmented worms.
Some characteristics of Annelids are:
1. Segmented bodies.
2. Bilaterally symmetrical.
3. First organisms with organ level classification.
So the correct answer is 'Annelida'.

Choose the correct answers from the alternatives given:
Which one of the following is not a characteristic of the organisms included in the Kingdom Animalia?

  1. Multicellularity

  2. Presence of eukaryotic cells without walls

  3. Obtaining nutrients by ingestion

  4. Storage of carbohydrates as starch
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Animals show different types of body organization. They are multicellular.
Animals can be Asymmetric, Radial and Bilateral symmetric.  Most of the animals are triploblastic. They obtain nutrients by ingestion, so they have a heterotrophic mode of nutrition. They store glycogen as the reserve food material.
Hence, the correct answer is 'Storage of carbohydrate as starch'.

Mark the odd one in the series.
Plantae, Chordata, Tracheophyta, Eucalyptus

  1. Plantae

  2. Chordata

  3. Tracheophyta

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

Plantae- Plant kingdom

Chordata- Animal phylum
Tracheophyta-Plant phylum
Eucalyptus- Plant genus
Hence, of all the above only chordata is a rank associated with the animals and the rest are all associated to plants.
So, the correct answer is 'Chordata'.

Which of the following is correct matching set of Phylum and its three examples?

  1. Annelid - Nereis, Pheretima and Apis

  2. Echinodermata - Ophiura, Antedon and Cucumaria

  3. Mollusca - Dentalium, Pinctada, Hirudinaria

  4. Aschelminthes - Ancylosytoma, Wuchereria and Asterias
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Ophiura or the serpent star is a species of the brittle star in the order Ophiurida belonging to the phylum Echinodermata and class Ophiuroidea.
  • Antedon is a genus of free-swimming, stemless crinoids belonging to the phylum Echinodermata and class Crinoidea.
  • Cucumaria is a genus of sea cucumbers belonging to the phylum Echinodermata and class Holothuroidea.
  • Hence Echinodermata - Ophiura, Antedon, and Cucumaria is a correct matching set of Phylum and its three examples.
  • So, the correct answer is 'Echinodermata - Ophiura, Antedon, and Cucumaria'.
