Worked practice questions

A lab sorts cells into two groups: eukaryotic and one other group named:

  1. Prokaryotic
  2. Panoramic
  3. Pneumatic
  4. Prismatic
Show answer and solution

Correct answer: A. Prokaryotic

1. Cells differ mainly by whether they hold a nucleus. 2. That single split covers every known cell. 3. The other group is the prokaryotic one. _Source: OpenStax Biology 2e, Chapter 4, Cell Structure._

A student sees a simple cell with no nucleus under a scope. That cell is a:

  1. Production
  2. Prokaryote
  3. Proteinase
  4. Protonator
Show answer and solution

Correct answer: B. Prokaryote

1. A missing nucleus is the giveaway. 2. No membrane bound organelle is present either. 3. So the cell is a prokaryote. _Source: OpenStax Biology 2e, Chapter 4, Cell Structure._

A teacher lists the only two groups counted as prokaryotes. They are Archaea and:

  1. Bacteria
  2. Beetles
  3. Bracken
  4. Barnacle
Show answer and solution

Correct answer: A. Bacteria

1. Prokaryotes are mostly single celled. 2. Only two domains fit that description. 3. They are Bacteria and Archaea. _Source: OpenStax Biology 2e, Chapter 4, Cell Structure._
