Question

Each of the following characteristics represent a Kingdom proposed by Whittaker. Arrange the following in increasing order of complexity of body organisation.

1. Multicellular heterotrophs with cell wall made of chitin.
2. Heterotrophs with tissue/organ/organ system level of body organisation.
3. Prokaryotes with cell wall made of polysaccharides and amino acids.
4. Eukaryotic autotrophs with tissue/organ level of body organisation.
5. Eukaryotes with cellular body organisation.

Choose the correct answer from the options given below:

Options

• A, C, E, B, D

• C, E, A, D, B

• A, C, E, D, B

• C, E, A, B, D

Answer 1

C, E, A, D, B

Explanation:

Analyze each option:

1. Multicellular heterotrophs with cell wall made of chitin → Kingdom Fungi - multicellular, but lower complexity (no tissues).
2. Heterotrophs with tissue/organ/organ system level of body organisation → Kingdom Animalia - most complex.
3. Prokaryotes with cell wall made of polysaccharides and amino acids → Kingdom Monera - simplest.
4. Eukaryotic autotrophs with tissue/organ level of body organisation → Kingdom - Plantae highly complex but less than animals.
5. Eukaryotes with cellular body organisation → Kingdom Protista - unicellular eukaryotes.

Thus, the correct increasing order is: C (Monera), E (Protista), A (Fungi), D (Plantae), B (Animalia)
