Diversity in Living Organisms

3,829 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.

  1. The development of sticky feet by the red-eyed frog

  2. Monkeys having long tails

  3. Toucan bird developing short, pointed beak for reaching its food

  4. Lions having sensitive hearing and sharp eyesight

  5. Elephants having big trunk

C Correct answer
Explanation

This is the correct option as this is not an adaptation of toucan bird. They have large, long beak to reach fruits on branches that are too weak to support the weight of the bird.

Multiple choice

Which of the following statements are FALSE regarding fungi?

  1. Food materials are stored in the form of starch.
  2. The cell wall is made up of chitin.
  3. Fungi are always autotrophs.
  4. Thallus is made up of pseudo parenchyma.

  1. Only 1 and 2

  2. Only 1and 3

  3. Only 1and 4

  4. Only 2 and 3

  5. Only 3 and 4

B Correct answer
Explanation

Yes, it is correct, as both are false. In fungi, food materials are stored in the form of glycogen, and fungi are heterotrophs due to absence of chlorophyll.

Multiple choice

Which of the following is only a set of neutrophiles?

  1. Alicyclobacillus, Ferroplasma and Sulfolobus

  2. Escherichia, Euglena and Paramecium

  3. Escherichia, Picrophilus and Sulfolobus

  4. Paramecium, Ferroplasma and Picrophilus

  5. Euglena, Paramecium and Natronobacterium

B Correct answer
Explanation

It is the correct answer. All are neutrophiles. Escherichia, Euglena and Paramecium, all are Neutrophiles (optimum growth between pH 5.5 and 8.0).

Multiple choice

Which of these is an example of analogous organs?

  1. Forelimbs of whales, bats, cheetahs and humans

  2. Thorns and tendrils of bougainvillea and cucurbita

  3. Eyes of octopi and mammals

  4. Mouth parts of a honey bee and a mosquito

  5. Vertebrae of giraffes, whales and human beings
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The eyes of octopi and mammals are examples of analogous organs. They show superficial resemblance and perform similar functions but have different internal structures.

Multiple choice

Which of the following statements does not characterise fungi?

  1. Fungi are autotrophic organisms.

  2. Fungal cells contain membrane-bound nuclei.

  3. Fungi have a cell wall.

  4. Some fungi display the phenomenon of bioluminescence.

  5. The fungi have haploid nuclei.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

This is the incorrect statement as fungi lack chloroplasts and are heterotrophic organisms and require preformed organic compounds as energy sources.

Multiple choice

  1. Prokaryotes have monosystromic type of mRNA.

  2. Prokaryotes have 80S types of ribosomes.

  3. Prokaryotes have a capsule of mucopolysaccharide.

  4. There is only one fibril in flagella of prokaryotes.
