Worked practice questions

A feature common to plant sieve-tube cells and mature mammalian RBCs is

  1. absence of nucleus
  2. presence of cell wall
  3. presence of chloroplasts
  4. large vacuole
Show answer and solution

Correct answer: A. absence of nucleus

Mature sieve-tube elements lose their nucleus mammalian erythrocytes also lack a nucleus at maturity.

The 'powerhouse of the cell' is the

  1. ribosome
  2. lysosome
  3. nucleus
  4. mitochondrion
Show answer and solution

Correct answer: D. mitochondrion

Mitochondria carry out aerobic respiration, producing most of the cell's ATP.

A feature common to prokaryotes and many eukaryotes (e.g. plants, fungi) is

  1. mitochondria
  2. membrane-bound organelles
  3. a true nucleus
  4. a cell wall
Show answer and solution

Correct answer: D. a cell wall

Both prokaryotes and many eukaryotes (plants, fungi) have cell walls only eukaryotes have a true nucleus and membrane-bound organelles.
