Kingdom Monera in Whittaker’s Five Kingdom classification is not characterized by:
1. Prokaryote cell type
2. Cellulosic cell wall
3. Absence of nuclear membrane
4. Cellular body organization
Phylogenetic classification is based on:
1. | Morphological similarities | 2. | Physiological similarities |
3. | Reproductive similarities | 4. | Evolutionary relationships |
In Whittaker’s Five Kingdom classification, heterotrophic mode of nutrition is present in members of:
1. | Two kingdoms | 2. | Three kingdoms |
3. | Four kingdoms | 4. | Five kingdoms |
The main criteria for classification used by Whittaker included all the following, except:
1. Cell structure and body organization
2. Mode of nutrition
3. Mode of reproduction
4. Mode of locomotion

As a group the most extensive metabolic diversity is shown by:
1. | Bacteria | 2. | Protista |
3. | Fungi | 4. | Animals |
The vast majority of bacteria are:
1. | Heterotrophs | 2. | Photoautotrophs |
3. | Chemosynthetic autotrophs | 4. | Methanotrophs |
Halophiles are archaebacteria adapted to extreme:
1. | Hot habitats | 2. | Saline habitats |
3. | Marshy habitats | 4. | Cold habitats |
Chemosynthestic autotrophic bacteria:
I. | Produce ATP by oxidizing inorganic substances |
II. | Play a great role in recycling nutrients like nitrogen, phosphorus, iron and sulfur |
1. | Both I and II are correct | 2. | Only I is correct |
3. | Only II is correct | 4. | Both I and II are incorrect |
Consider the given two statements:
I: | Mycoplasma are naturally resistant to antibiotics that target cell wall synthesis |
II: | They are the smallest bacteria discovered yet |
1. Both I and II are correct and II explains I
2. Both I and II are correct but II does not explain I
3. I is correct but II is incorrect
4. Both I and II are incorrect
