Which observation proves that a cell is a eukaryote?
Which observation proves that a cell is a eukaryote?
A) It contains DNA
B) It contains ribosomes
C) It has a cell membrane
D) It has DNA inside a nucleus
Homework Answers
An eukaryotic cell is the cell which exhibit membrane bound organelles. They exhibit a well defined membrane bound nucleus in which the DNA (deoxyribo nucleic acid) resides it is the genetic material which is passed on from parents to their offsprings. This property of the eukaryotic cell makes it distinct from prokaryotic cell as the prokaryotic cell lack a nucleus.
So, the anwer is B
