Worked practice questions

Cells that possess a membrane-bound, well-organised nucleus are called:

  1. acellular bodies
  2. eukaryotic cells
  3. prokaryotic cells
  4. viral particles
Show answer and solution

Correct answer: B. eukaryotic cells

Cells with a membrane-bound nucleus are eukaryotic; those without are prokaryotic.

Cells that lack a membrane-bound nucleus are called:

  1. gametes
  2. somatic cells
  3. eukaryotic cells
  4. prokaryotic cells
Show answer and solution

Correct answer: D. prokaryotic cells

Prokaryotic cells lack a membrane-bound nucleus (and membrane-bound organelles).

The scientist who first observed and described a living cell was:

  1. Schwann
  2. Robert Brown
  3. Antonie van Leeuwenhoek
  4. Robert Hooke
Show answer and solution

Correct answer: C. Antonie van Leeuwenhoek

Antonie van Leeuwenhoek first saw and described a live cell Robert Hooke had earlier seen dead cork cells.
