Sample Biology questions, answered.

Taken straight from the papers below — one from each of the most recent years, with the answer marked and the reasoning written out.

JAMB Biology 2026 · Question 1
Bacteria belong to the kingdom
  1. Fungi
  2. Plantae
  3. Prokaryotae — correct answer
  4. Protoctista
Worked solution
Bacteria are prokaryotic organisms classified under the kingdom Prokaryotae (Monera), distinct from Fungi, Plantae, and Protoctista, which are made up of eukaryotic organisms.
JAMB Biology 2025 · Question 1
As a group, acoelomates are characterized by
  1. the absence of a brain
  2. the absence of mesoderm
  3. a coelom that is not completely lined with mesoderm
  4. a solid body without a cavity surrounding internal organs — correct answer
Worked solution
Acoelomates lack a body cavity altogether; the space between their body wall and internal organs is filled with solid mesenchyme tissue, unlike coelomates (a true, fully mesoderm-lined cavity) or pseudocoelomates (a cavity only partly lined with mesoderm).
JAMB Biology 2024 · Question 1
A major difference between onion cells and cheek cells is that
  1. Cheek cells are irregular in shape — correct answer
  2. Onion cells are spherical in shape
  3. Cheek cells are not edible
  4. Onion cells contain glycogen
Worked solution
Onion cells are plant cells with a rigid cellulose cell wall, giving them a regular, brick-like shape, whereas cheek cells are animal cells that lack a cell wall and so appear irregular and flattened in shape. Onion cells store starch, not glycogen, which rules out option D.
JAMB Biology 2023 · Question 1
Living animals release carbon dioxide. Which life process is being exhibited?
  1. Sensitivity
  2. Excretion — correct answer
  3. Movement
  4. Nutrition
Worked solution
The removal of metabolic waste products such as carbon dioxide from the body is excretion, one of the seven characteristics of living things.
JAMB Biology 2022 · Question 1
Euglena cannot be regarded definitely as an animal cell because it has
  1. Flagellum
  2. eyespot
  3. pellicle
  4. chloroplast — correct answer
Worked solution
The presence of chloroplasts, which allow Euglena to photosynthesise like a plant, makes it impossible to classify Euglena definitely as an animal cell, since photosynthetic ability is a plant-like characteristic.

Before you sit it

How JAMB Biology is set.

Joint Admissions and Matriculation Board (UTME) sets 40 questions in Biology, answered in 45 minutes — about 68 seconds a question. Practising against that clock is the part most candidates skip, and it is the part that costs marks.

We hold 1,379 published Biology questions spanning 1997 to 2026. You can practise any single year’s paper, or sit a full timed mock that mirrors the real interface — the navigator, the flags and the auto-submit included.

Every question you get wrong comes back the next day, then at longer gaps until it sticks, and your home page leads with your weakest subjects.
