Multiple choice biology classification of living beings hierarchy of classification different types of classifications introduction to classification of living organisms

The two kingdom classification of Linnaeus is proved to be ineffective in the case of which of the following organism/s?

  1. Fungi

  2. Lichens

  3. Euglena

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In the two-kingdom classification given by Linnaeus, all organisms were classified into plants and animals. This system, however, did not distinguish between eukaryotes and prokaryotes/unicellular and multicellular organisms/ photosynthetic and nonphotosynthetic organisms in which a large number of organisms did not fit. Lichens and fungi were classified under Plantae and euglena under Animalia.

So, the correct option is 'all of the above'.
