Question

Consider the following classification.
Lotus, Rose, Tiger, Cactus
Which of the following is not suitable in a given classification?
A) Lotus
B) Rose
C) Tiger
D. Cactus

Answer 1

Hint: Living organisms are grouped on the basis of their similarities by means of biological classification. Traditionally physical similarities were the basis of classification. As technology and science progressed, classification based on anatomy as well as genetics have also been adopted.

Complete answer:
In the given classification out of the four living organisms given, three are plants and one is an animal. Lotus, Rose, and Cactus are classified under kingdom Plantae, while Tiger comes under kingdom Animalia.

Considering the other given options:
A. Lotus is suitable for the classification since the organism comes under kingdom Plantae and fulfills the criteria for being a plant such as being able to carry out photosynthesis and having a cell wall as the outermost cellular layer. Thus it is not the right option.
B. Rose is suitable for the classification since the organism come under kingdom Plantae and fulfills the criteria for being a plant such as being able to carry out photosynthesis and having a cell wall as the outermost cellular layer. Thus it is not the right option.
D. Cactus is suitable for the classification since the organism come under kingdom Plantae and fulfills the criteria for being a plant such as being able to carry out photosynthesis and having a cell wall as the outermost cellular layer. Thus it is not the right option.
Hence from the answer is ‘Tiger’. Since tiger comes under kingdom Animalia and is an animal while other three organisms come under kingdom plantae and are plants hence cannot be included in the classification.

Thus the correct answer is option ‘C’.

Note: According to biological classification living organisms are arranged into groups and further into sub groups on the basis of degree of similarities between each other. Aristotle was the first person to put forth the idea of classification. The basis of this classification was the habitat of organisms such as air, water, and land.
