Answers
dear student here my answer
the pair of groups which share more number of similar characteristics are considered evolutionary closer group.
so X and Y are more closely related.
multi cellular Eukaryota organism are classified mainly on the basis of mode of nutrition.
* Fungi show heterotrophic mode of nutrition (mostly saprophytic few are parasitic).
* plant show autotrophic mode of nutrition except few plant which are parasitic.
* animals show heterotrophic mode of nutrition
another criteria for further classification of multi cellular eukaryotes is presence or absence of cell wall .
*fungi have cell wall made up of chitin and polysacchirides .
* plants have cell wall made up of cellulose.
* cell wall is absent in animals.
