Consider the following statements with respect to characteristic features of the kingdom.
(i) In animalia, the mode of nutrition is autotrophic.
(ii) In monera, the nuclear membrane is present.
(iii) In protista, the cell type is prokaryotic.
(iv) In plantae, the cell wall is present.
Of the above statements, which one is correct ?
(i) only
(ii) only
(iii) only
(iv) only
Correct Answer :
D. (iv) only
Kingdom animalia includes all heterotrophic, multicellular complex eukaryotes. They depend either upon plants or on other animals for their food requirements. Kingdom monera includes prokaryotic organisms lacking membrane bound nucleus. Hence, nuclear membrane cannot be found in Monera. Protista is a eukaryotic kingdom.
