Question

why are animals included under eukaryotes

Answer 1

Animal cells are typical of the eukaryotic cell, enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles. Unlike the eukaryotic cells of plants and fungi, animal cells do not have a cell wall.

Answer 2

since eukaryotes have organelles they are much more complex cells than prokaryotes. Usually, eukaryotic cells are bigger than prokaryotic cells. These cells are often part of multi-cellular organisms, such as in animals, plants, and fungi.
