A cell that lacks a membrane surrounded nucleus is called?

Question

A. Prokaryote

B. Eukaryote

C. Autotrophic

D. Chemosynthetic

Answer 1

You can knock out C and D - these are adjectives, and the question is clearly asking for a noun.  That's a handy trick whenever you're having trouble with multiple choice.

The other part, you just have to know.  See answers above.  A is correct.

Answer 2

None of these is correct.

First: Prokaryotes, by definition, do not contain a nucleus, instead the DNA-containing region is termed a nucleoid.

Second: the questions grammatically flawed. In its current state picking a noun for the answer would be incorrect.

Answer 3

A, because a prokaryote is bacteria, or simple cell. A eukaryote is a complex cell.

Answer 4

A. Prokaryote

Answer 5

A
