Q1. Which structure is found in a plant cell but not in an animal cell?
  • A.  Mitochondrion
  • B.  Cell wall made of cellulose
  • C.  Cell membrane
  • D.  Ribosome
Show answer & explanation
✓ Answer: B. Cell wall made of cellulose
Plant cells have a rigid cell wall made of cellulose that supports and strengthens the cell; animal cells have no cell wall. Mitochondria, ribosomes and the cell membrane are found in both plant and animal cells.
Q2. Where in the human body is bile produced?
  • A.  The liver
  • B.  The gall bladder
  • C.  The pancreas
  • D.  The stomach
Show answer & explanation
✓ Answer: A. The liver
Bile is produced in the liver and then stored in the gall bladder before being released into the small intestine. A common misconception is that the gall bladder makes bile, but it only stores and concentrates it.
Q3. Which of the following best describes a potential risk sometimes associated with vaccination programmes?
  • A.  Mild side effects such as soreness or a low fever can occur, though serious reactions are very rare
  • B.  Vaccines always cause the full-blown disease they are meant to prevent
  • C.  Vaccines permanently weaken the immune system
  • D.  Vaccines contain live, fully virulent pathogens in every case
Show answer & explanation
✓ Answer: A. Mild side effects such as soreness or a low fever can occur, though serious reactions are very rare
Vaccines can occasionally cause mild side effects like soreness at the injection site or a slight fever, but serious adverse reactions are extremely rare and are heavily outweighed by the benefits of preventing serious disease. Most vaccines use dead or weakened pathogens, or fragments of them, so they do not cause the full disease.
