Support and Movement: JAMB Biology Questions, Answers & Notes

What Support and Movement covers in the JAMB Biology syllabus

Support and movement let organisms find food, escape danger and reproduce. Animals use skeletons: endoskeletons (internal bone, in mammals), exoskeletons (external chitin, in insects) and hydrostatic skeletons (fluid-filled, in earthworms). Bones meet at joints — ball-and-socket (shoulder/hip, many directions) and hinge (elbow/knee, one plane) — held by ligaments (bone to bone), with cartilage cushioning the ends; tendons attach muscles to bones. Muscles work in antagonistic pairs (biceps contracts as triceps relaxes). The skeleton also protects organs and makes blood cells. Plants are supported by turgor pressure (herbaceous plants wilt when flaccid) and by lignified xylem/wood.

For Support and Movement, JAMB expects you to be able to:

• Explain the need for support and movement and types of skeleton
• Describe joints, ligaments, tendons and antagonistic muscles
• Explain support in plants (turgor, wood) and functions of the skeleton

Key facts & revision notes: Support and Movement

These are the recurring points our Support and Movement questions test — revise them until each feels automatic, then practise the questions above to lock them in.

• The skeleton (bones) supports the body, protects organs and enables movement.
• An endoskeleton (bone) is internal, as in vertebrates.
• Insects have an external skeleton (exoskeleton) made of chitin.
• A joint is where bones meet, allowing (or preventing) movement.
• Ligaments connect bone to bone at joints; tendons connect muscle to bone.
• Tendons attach muscles to bones so that muscle contraction moves the bone.
• A ball-and-socket joint (shoulder, hip) allows movement in many directions.
• A hinge joint (elbow, knee) allows movement in one plane, like a door hinge.
• Antagonistic muscles (e.g.
• biceps and triceps) work in opposite pairs to move a bone both ways.
• To bend the arm, the biceps contracts while the triceps relaxes (antagonistic action).
• Herbaceous plants are held upright mainly by turgor pressure in their cells.
• When cells lose water they become flaccid (lose turgor), so the plant wilts and droops.
• Woody support comes largely from lignified xylem (wood) and strengthening tissue like sclerenchyma.
• Cartilage covers bone ends at joints, reducing friction and cushioning against shock.
• The skeleton supports, protects vital organs, allows movement and makes blood cells in bone marrow.
• An earthworm has a hydrostatic skeleton — a fluid-filled body cavity that provides support.
• Voluntary (skeletal) muscles are under conscious control, e.g.
• Cardiac muscle is found only in the heart and contracts rhythmically without tiring.
• Movement lets animals find food, escape predators, find mates and disperse.
• The vertebral column encloses and protects the spinal cord.
• The skeleton consists of bones and cartilage.
• The axial skeleton is the central supporting framework.
• Limb bones form the appendicular skeleton.

Worked examples

Three Support and Movement questions with the answer and a short explanation, so you can see how the topic is set before you practise the full set.

How Support and Movement is tested in JAMB Biology

Our Support and Movement bank holds 40 questions (3 easy, 24 medium, 13 hard). JAMB Biology typically returns to Support and Movement year after year, so steady practice on this topic is high-value revision. Questions are multiple-choice with four options, and at UTME pace you get roughly 40 seconds each — which is why timed practice matters.

How to answer Support and Movement questions

Work the stem first and predict the answer before you look at the options; then eliminate the ones that contradict the key facts above. Watch for “which is not…”, “all of the above” and “except” style stems, which are where rushed candidates lose easy marks on Support and Movement. If a calculation or a precise definition is involved, work it from first principles rather than guessing from a half-remembered rule. When two options look right, re-read the stem for the qualifier that separates them — JAMB rarely repeats an option by accident. If you are still unsure, eliminate the two weakest choices to lift your odds, flag the question, and move on; never burn a full minute on one Biology item when the exam gives you about forty seconds each. Then come back to flagged questions with whatever time remains. The single most reliable way to get faster at Support and Movement is repeated timed practice, so use the button above until the recurring patterns feel automatic.

Common mistakes to avoid in Support and Movement

The errors that cost marks on Support and Movement are usually careless rather than conceptual: misreading a negative stem, confusing two similar terms, or rushing a definition you actually know. Candidates also over-rely on “expo” and last-minute cramming instead of understanding the topic — which fails the moment JAMB rephrases a familiar idea. Treat every option as a claim to be checked against the facts above, keep your working tidy for any calculation, and don’t change a considered answer on a hunch. Above all, revise Support and Movement actively by answering questions, not just by re-reading notes — recall under time is what the exam rewards.

Frequently asked questions

Is Support and Movement part of the JAMB Biology syllabus?

Yes. Support and Movement is a recognised topic in the JAMB Biology syllabus, covering explain the need for support and movement and types of skeleton. You should be able to recall its key facts and apply them to multiple-choice questions.
