The scientist who first discovered cells while looking at a thin slice of cork was:
A. Isaac Newton
B. Robert Hooke ✓ Correct
C. Louis Pasteur
D. Charles Darwin
Solution: Robert Hooke saw tiny box-like spaces in cork in 1665 and named them cells.
Q2 — Structure of a Cell · easy · theory
The smallest basic unit that makes up the body of every living thing is the:
A. Brick
B. Atom
C. Cell ✓ Correct
D. Organ
Solution: The cell is the basic building block of all living things.
Q3 — Structure of a Cell · easy · theory
To see a single cell clearly, we need to use a:
A. Telescope
B. Stethoscope
C. Magnet
D. Microscope ✓ Correct
Solution: Cells are far too small to see with the naked eye, so we use a microscope.
Q4 — Structure of a Cell · easy · theory
The part of a cell that controls all its activities, like a captain, is the:
A. Cell wall
B. Cell membrane
C. Nucleus ✓ Correct
D. Cytoplasm
Solution: The nucleus is the control centre of the cell and directs its work.
Q5 — Structure of a Cell · medium · theory
The jelly-like material that fills the cell and where many life activities take place is called:
A. Nucleus
B. Cytoplasm ✓ Correct
C. Cell wall
D. Cell membrane
Solution: Cytoplasm is the jelly-like fluid inside a cell where its activities happen.
Q6 — Structure of a Cell · medium · theory
The thin outer covering that surrounds a cell and controls what goes in and out is the:
A. Nucleus
B. Cytoplasm
C. Chloroplast
D. Cell membrane ✓ Correct
Solution: The cell membrane is the outer boundary that decides what enters or leaves the cell.
Q7 — Structure of a Cell · medium · theory
Amoeba is made up of only one cell. An organism made of a single cell is said to be:
A. Multicellular
B. Unicellular ✓ Correct
C. Non-living
D. Colourless
Solution: Uni means one, so an organism made of a single cell, like Amoeba, is unicellular.
Q8 — Structure of a Cell · medium · theory
Which group correctly names three parts found in almost every cell?
A. Cell membrane, cytoplasm and nucleus ✓ Correct
B. Bricks, cement and sand
C. Roots, stem and leaves
D. Brain, heart and lungs
Solution: Nearly every cell has a cell membrane, cytoplasm inside it, and a nucleus.
Q9 — Structure of a Cell · hard · theory
Which is the longest cell found in the human body?
A. Blood cell
B. Bone cell
C. Skin cell
D. Nerve cell ✓ Correct
Solution: A nerve cell can be very long as it carries messages over long distances in the body.
Q10 — Structure of a Cell · hard · theory
A human being is made of billions of cells, while an Amoeba is made of just one cell. This tells us that:
A. Cells are found only in humans
B. An Amoeba is non-living
C. Both are living things made of cells ✓ Correct
D. Only the human is a living thing
Solution: Every living thing is made of cells, whether it has one cell or billions of them.
