Unit 2: Cells Test Review

A biologist working in a lab receives a sample of an unidentified organism. After some analysis the organism has the characteristics listed in the table

Which of the following students' correctly justified their identification of the organism?

• Sarah said the cell is a Prokaryote because the DNA is not housed within a nucleus.

• Devon said the cell is a Prokaryote because it is small in size.

• Marissa said the cell is a Eukaryote because it has a cell wall.

• Alvin said the cell is a Eukaryote because it has DNA.
