Cells, Tissues and Systems of the Human Body: JAMB Physical and Health Education Questions, Answers & Notes

What Cells, Tissues and Systems of the Human Body covers in the JAMB Physical and Health Education syllabus

The body is organised in levels. The cell is the basic structural and functional unit of the body (the basic unit of life), usually seen only with a microscope; its main parts are the nucleus (the control centre, which controls the cell's activities), the cytoplasm (the jelly-like substance where reactions occur), the cell membrane (which controls what enters and leaves) and the mitochondrion (the 'powerhouse' that releases energy). A group of similar cells forms a tissue (e.g. muscle, nerve, bone, blood); a group of tissues forms an organ (e.g. heart, lungs, stomach); a group of organs forms a system (e.g. the digestive system); and several systems together make up the whole organism (body). The main point: the body is organised in levels from cells to tissues to organs to systems.

For Cells, Tissues and Systems of the Human Body, JAMB expects you to be able to:

• Define the cell (basic unit) and its parts (nucleus, cytoplasm, membrane, mitochondrion)
• Explain levels of organisation (cell → tissue → organ → system → organism)
• Give examples of tissues (muscle, nerve, bone, blood), organs (heart, lungs) and systems

Key facts & revision notes: Cells, Tissues and Systems of the Human Body

These are the recurring points our Cells, Tissues and Systems of the Human Body questions test — revise them until each feels automatic, then practise the questions above to lock them in.

• The cell is the basic structural and functional unit of the body.
• A group of similar cells performing the same function forms a tissue.
• A group of tissues working together forms an organ.
• A group of organs working together forms a system (organ system).
• The nucleus controls the cell's activities.
• The cytoplasm is the jelly-like substance inside the cell where reactions occur.
• The cell (plasma) membrane surrounds the cell and controls what enters and leaves.
• Body organisation from smallest goes cell → tissue → organ → system → organism.
• Muscle, nerve, bone and blood are examples of body tissues.
• The heart, lungs and stomach are examples of body organs.
• The mitochondrion is the 'powerhouse' of the cell, releasing energy.
• The digestive system is an example of a body system (a group of organs).
• Cells are usually seen with a microscope because they are very small.
• The correct order from smallest is cell → tissue → organ → system.
• The nucleus is often called the control centre of the cell.
• The cell is the basic unit of life.
• A tissue is made up of many similar cells.
• Several systems working together make up the whole organism (body).
• The cell membrane controls what enters and leaves the cell.
• The main point is that the body is organised in levels from cells to tissues to organs to systems.

Worked examples

Three Cells, Tissues and Systems of the Human Body questions with the answer and a short explanation, so you can see how the topic is set before you practise the full set.

How Cells, Tissues and Systems of the Human Body is tested in JAMB Physical and Health Education

Our Cells, Tissues and Systems of the Human Body bank holds 20 questions (3 easy, 14 medium, 3 hard). JAMB Physical and Health Education typically returns to Cells, Tissues and Systems of the Human Body 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 Cells, Tissues and Systems of the Human Body 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 Cells, Tissues and Systems of the Human Body. 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 Physical and Health Education 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 Cells, Tissues and Systems of the Human Body is repeated timed practice, so use the button above until the recurring patterns feel automatic.

Common mistakes to avoid in Cells, Tissues and Systems of the Human Body

The errors that cost marks on Cells, Tissues and Systems of the Human Body 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 Cells, Tissues and Systems of the Human Body actively by answering questions, not just by re-reading notes — recall under time is what the exam rewards.
