WASSCE Biology is the West African Examinations Council senior secondary Biology examination taken in Nigeria, Ghana, Sierra Leone, The Gambia and Liberia. It is assessed across three papers totalling 200 marks: Paper 1 is a 50-question multiple-choice objective test sat in 50 minutes, Paper 2 is a 1 hour 40 minute essay paper, and Paper 3 is a 2 hour practical. Subjects are graded A1 to F9, with A1-C6 counting as a credit pass that most universities and employers require. The Paper 1 objective questions are drawn from the common Section A of the syllabus, covering cell biology, plant and animal physiology, ecology, genetics, evolution and classification. This 100-question bank provides original objective-style practice across those topics with explanations for every option.

1Which of the following is NOT one of the seven characteristics of living things?

A.Movement

B.Respiration

C.Crystallisation

D.Reproduction

Explanation: The characteristics of living things are commonly remembered as MRS GREN: Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion and Nutrition. Crystallisation is a physical process shown by some non-living substances and is not a life process.

2The part of a plant cell responsible for trapping light energy for photosynthesis is the

A.mitochondrion

B.chloroplast

C.vacuole

D.ribosome

Explanation: Chloroplasts contain the green pigment chlorophyll, which absorbs light energy and uses it to convert carbon dioxide and water into glucose during photosynthesis. They are found in the green parts of plants such as leaves.

3Which structure is present in a plant cell but absent in an animal cell?

A.Cell membrane

B.Nucleus

C.Cell wall

D.Cytoplasm

Explanation: The cellulose cell wall surrounds the cell membrane in plant cells, giving them a fixed shape and support. Animal cells lack a cell wall and are bounded only by the cell membrane.

4The control centre of the cell that carries the hereditary material is the

A.nucleus

B.cytoplasm

C.cell membrane

D.Golgi body

Explanation: The nucleus contains the chromosomes made of DNA, which carry the genetic information that controls cell activities and is passed to offspring. It directs growth, metabolism and reproduction.

5The movement of water molecules from a region of high water potential to a region of low water potential through a semi-permeable membrane is called

A.diffusion

B.osmosis

C.active transport

D.plasmolysis

Explanation: Osmosis is the net movement of water molecules across a semi-permeable membrane from a dilute solution (high water potential) to a more concentrated solution (low water potential). It is a special case of diffusion involving water and a membrane.

6Which process requires energy to move substances against a concentration gradient?

A.Diffusion

B.Osmosis

C.Active transport

D.Evaporation

Explanation: Active transport moves molecules or ions from a region of lower concentration to one of higher concentration, against the gradient, and therefore requires energy supplied by ATP from respiration. An example is the uptake of mineral ions by root hair cells.

7The correct sequence of levels of organisation in a multicellular organism is

A.cell, tissue, organ, system

B.tissue, cell, system, organ

C.organ, system, tissue, cell

D.system, organ, cell, tissue

Explanation: Cells of similar structure group to form tissues, different tissues form organs, and organs working together form a system. This increasing complexity is the standard hierarchy of organisation in living things.

8Organisms whose cells lack a true membrane-bound nucleus are classified as

A.eukaryotes

B.prokaryotes

C.protists

D.fungi

Explanation: Prokaryotes, such as bacteria and blue-green algae, have no true nucleus; their genetic material lies free in the cytoplasm. Their cells also lack membrane-bound organelles such as mitochondria.

9In the five-kingdom system of classification, mushrooms and moulds belong to the kingdom

A.Plantae

B.Animalia

C.Fungi

D.Monera

Explanation: Fungi such as mushrooms and moulds are eukaryotic, have cell walls made of chitin and feed by absorbing nutrients (saprophytic or parasitic nutrition). They cannot photosynthesise, so they are placed in their own kingdom, Fungi.

10A device used to identify and classify organisms based on a series of paired contrasting features is called a

A.dichotomous key

B.food web

C.pyramid of numbers

D.cladogram chart

Explanation: A dichotomous key offers a series of paired statements; at each step the user chooses one of two contrasting descriptions, gradually narrowing down to the identity of the organism. It is the standard tool for identifying living things in the field.

About the WASSCE Biology Exam

The West African Senior School Certificate Examination (WASSCE) Biology paper is a school-leaving science subject taken by senior secondary candidates in Nigeria, Ghana, Sierra Leone, The Gambia and Liberia, administered by the West African Examinations Council (WAEC). Biology is assessed across three papers totalling 200 marks: Paper 1, a 50-question multiple-choice objective test drawn from the common Section A of the syllabus; Paper 2, an essay/theory paper of six questions; and Paper 3, a practical paper. The syllabus covers the concept of living things and classification, cell organisation and cellular processes, plant and animal nutrition, transport, respiration, excretion, homeostasis and coordination, support and movement, reproduction, ecology, microorganisms and health, genetics and variation, and evolution. WAEC offers both a School Candidates sitting (May/June) and a Private Candidates / GCE sitting (November/December and a second May/June series).

Assessment

Paper 1 (Objective): 50 multiple-choice questions from the common Section A. Paper 2 (Essay): six essay questions across three sections. Paper 3 (Practical): three sections testing laboratory work and specimen analysis. Total 200 marks.

Time Limit

Paper 1: 50 minutes; Paper 2: 1 hour 40 minutes; Paper 3: 2 hours.

Passing Score

No single pass mark. Subjects are graded A1 (Excellent) to F9 (Fail). A1-C6 is a credit pass (the standard required by most universities and employers), D7-E8 is a weak pass and F9 is a fail.

Exam Fee

WASSCE registration fees are set per country and session by WAEC and national ministries and are paid through the school (School Candidates) or directly (Private Candidates); confirm the current amount with your school or WAEC office. (West African Examinations Council (WAEC))

WASSCE Biology Study Tips from Top Performers

1Practise the 50 objective questions under a 50-minute timer so you get used to spending about one minute per question and learn to move on from hard items and return to them.

2Learn the labelled diagrams that recur in Biology objective questions, such as the plant and animal cell, the nephron, the heart, the eye, the flower and the digestive system.

3Master the definitions and differences that examiners test repeatedly, for example diffusion versus osmosis versus active transport, and arteries versus veins versus capillaries.

4For ecology, be confident with food chains, food webs and trophic levels and be able to read pyramids of numbers and energy flow diagrams.

5For genetics, practise drawing monohybrid and simple dihybrid crosses and calculating phenotype and genotype ratios using a Punnett square.

6Use WAEC past objective papers to spot frequently tested areas such as classification, enzymes, transport and reproduction, then revise the underlying syllabus points.
