  1. There was no separate kingdom for prokaryotes

  2. Fungi was included in plantae

  3. Fungi was included in animalia

  4. None of the above

Show answer
Correct Option: B
Explanation:
Copeland proposed the four kingdom classification. He grouped all living organisms into four kingdoms, namely Kingdom Monera, Kingdom protista, Kingdom Metaphyta(Plantae) and Kingdom Metazoa(animalia).
He  included fungi in plantae despite being heterotrophic and having chitinous cell wall.
So, the correct option is 'Fungi was included in plantae'.

Initially, classification of living things was done as

  1. Fungi

  2. Lichens

  3. Euglena

  4. All of the above

Show answer
Correct Option: D
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'.

  1. Commensalism

  2. Mutualism

  3. Ammensalism

  4. Parasitism

Show answer
Correct Option: B
Explanation:

Mutualism refers to ecological association between two organisms of different species which mutually get benefitted by their association. In commensalism, one organism gets benefitted and the other is neither benefitted nor harmed. In amensalism, one organism is destroyed and the other remains unaffected. In parasitism, one organism (parasite) lives inside other organism (host) and harms its host.
