Activity 12.3 Let us Study

Question 1.

Study the concept map (Fig. given below). Class 9

Question 2.

List the criteria which form the basis of five kingdom classification. Class 9

Answer:

The criteria listed from the concept map are:

Cell type - prokaryote (no membrane-bound nucleus) or eukaryote (membrane-bound nucleus)

Cell structure - presence or absence of a cell wall; if present, whether it is made of chitin or cellulose Level of organisation - unicellular or multicellular

Mode of nutrition - autotrophic (producers) or heterotrophic (consumers or decomposers) Ecological role - producer, consumer, or decomposer

Question 3.

Compare the criteria you have listed after studying the concept map and the criteria given below: Class 9

Answer:

All four criteria listed match those visible in the concept map. The concept map additionally shows the material of the cell wall (chitin in Fungi, cellulose in Plantae) and the ecological role (decomposer, producer, consumer) as further distinguishing criteria within the eukaryotic kingdoms. Together, these criteria allow organisms to be placed in one of five kingdoms - Monera, Protista, Fungi, Plantae, or Animalia.
