Sample Grade 7 Science and Technology Practice Questions

Try these sample questions to test your Grade 7 Science and Technology exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which organelle controls the activities of a typical animal cell and contains the genetic material?
A.Mitochondrion
B.Nucleus
C.Cell wall
D.Chloroplast
Explanation: The nucleus is the control centre of the cell. It stores DNA (genetic material) and directs growth, repair, and reproduction. Mitochondria release energy; cell walls and chloroplasts are found in plant cells, not as the control centre.
2Which structure is present in a plant cell but absent in a typical animal cell?
A.Cell membrane
B.Cytoplasm
C.Cell wall
D.Nucleus
Explanation: Plant cells have a rigid cell wall made mainly of cellulose outside the cell membrane. Animal cells have a cell membrane, cytoplasm, and nucleus, but no cell wall.
3What is the main function of the excretory system in humans?
A.To digest food into simpler nutrients
B.To remove metabolic waste products from the body
C.To carry oxygen to body cells
D.To produce movement of the limbs
Explanation: The excretory system removes wastes such as urea, excess salts, and water (mainly via the kidneys and urine) so they do not build up and harm the body.
4Which pair of organs is most important for filtering blood and forming urine?
A.Lungs and heart
B.Kidneys and bladder
C.Stomach and liver
D.Brain and spinal cord
Explanation: The kidneys filter waste from blood to form urine; the bladder stores urine until it is passed out. Together they are central to the urinary/excretory pathway.
5Which blood vessel type carries blood away from the heart?
A.Veins
B.Arteries
C.Capillaries only
D.Lymph vessels
Explanation: Arteries carry blood away from the heart to the body (and to the lungs in the pulmonary artery). Veins return blood to the heart; capillaries are tiny exchange vessels between arteries and veins.
6What is the main job of red blood cells?
A.To fight infections by destroying pathogens
B.To transport oxygen using haemoglobin
C.To clot blood at a wound
D.To produce digestive enzymes
Explanation: Red blood cells contain haemoglobin, which binds oxygen in the lungs and releases it to body tissues. White cells fight infection; platelets help clotting.
7In flowering plants, which structure develops into a seed after fertilisation?
A.Petal
B.Sepal
C.Ovule
D.Anther
Explanation: After pollen fertilises the egg inside the ovule, the ovule develops into a seed. Petals attract pollinators; sepals protect the bud; anthers produce pollen.
8What is pollination in flowering plants?
A.The joining of male and female gametes inside the ovary
B.The transfer of pollen from anther to stigma
C.The opening of a seed coat during germination
D.The loss of water vapour from leaves
Explanation: Pollination is the transfer of pollen from the anther (male part) to the stigma (female part). Fertilisation is the later fusion of gametes after a pollen tube grows.
9Which statement correctly compares viruses and bacteria?
A.Both viruses and bacteria are always multicellular organisms
B.Bacteria are living cells that can reproduce independently; viruses need a host cell to multiply
C.Viruses are larger than bacteria and always have a cell wall
D.Bacteria cannot cause disease, but viruses always do
Explanation: Bacteria are cellular microorganisms that can grow and divide on their own under suitable conditions. Viruses are much smaller and must infect a living host cell to replicate.
10Fungi such as moulds and mushrooms obtain nutrients mainly by:
A.Photosynthesis using chlorophyll
B.Absorbing digested or decaying organic material
C.Hunting and swallowing prey like animals
D.Fixing nitrogen gas directly from the air only
Explanation: Most fungi are saprophytes or parasites: they secrete enzymes onto organic matter and absorb the soluble nutrients. They lack chlorophyll, so they do not photosynthesise.

Grade 7 Science and Technology Study Tips from Top Performers

1Draw and label cell, atom, circulatory and excretory diagrams from memory, then check against your notes.
2Connect soil properties (texture, structure, fertility) to plant growth examples from Lesotho farming contexts.
3Practise series of force/pressure/heat/electricity definitions with one concrete classroom experiment each.
4For ICT items, focus on purpose of Excel, PowerPoint and email rather than brand-specific menus.
5Use the scientific method language (observe, hypothesise, predict, test) when explaining investigations.

Frequently Asked Questions

What is Grade 7 Science and Technology?

It is the compulsory ECoL Grade 7 End-of-Level Science and Technology assessment. Scope comes from the NCDC Scientific and Technological learning area spanning science, agriculture, ICT, home economics and related strands.

How long is the official paper?

The 2025 final timetable lists Science and Technology code 4012 for 1 hour 30 minutes on 31 October 2025. Confirm the current year timetable.

Is this the same as LGCSE Physical Science or Biology?

No. Grade 7 Science and Technology is end-of-primary. LGCSE Physical Science 0181 and Biology 0180 are senior secondary syllabuses with different structure and depth.

Are these official ECoL questions?

No. Official assessment is a written paper. These MCQs are original study aids aligned to NCDC Grade 7 outcomes.
