CAMPBELL ESSENTIAL BIOLOGY 5E SIMON
YEH ACTUAL EXAM PAPER 2026
QUESTIONS WITH ANSWERS GRADED A+
⩥ Osmosis. Answer: A passive movement of water molecules through a
semi permeable membrane. Water moves from an area of low solute
concentration to high solute concentration
⩥ Active Transport. Answer: An active movement where an input of
energy is required. Particles move from low concentration to high
concentration
⩥ Facilitated Diffusion. Answer: A passive movement of particles from
high to low concentration through a protein channel in a cell.
⩥ Isotonic Solution. Answer: The same concentration of dissolved
substances. Water in = water out.
⩥ Hypertonic Solution. Answer: Higher concentration of solutes outside
cell than inside
⩥ Plasmolyse. Answer: When a cell has shrunk
,⩥ Hypotonic Solution. Answer: A cell has more solute inside than
outside.
⩥ Turgid. Answer: Cell may explode under pressure due to a hypotonic
solution.
⩥ Exocytosis. Answer: Movement out of a cell
⩥ Endocytosis. Answer: Movement into a cell
⩥ Lysosome. Answer: A vesicle that contains destructive/digestive
chemicals
⩥ Pinocytosis. Answer: A form of endocytosis where a cell engulfs
liquid into the cell.
⩥ Phagocytosis. Answer: A form of endocytosis where a cell engulfs
solids into a cell
⩥ Scientific question. Answer: Questions that can be answered by using
experiments and factual reasoning.
⩥ Biology. Answer: The study of living organisms and how they
function.
, ⩥ Scientific Method. Answer: A method of procedure that has
characterized natural science since the 17th century, consisting in
systematic observation, measurement, and experiment, and the
formulation, testing, and modification of hypotheses.
⩥ Hypothesis. Answer: 1st part of the scientific method
⩥ experimental design. Answer: Experimental design refers to how
participants are allocated to the different conditions (or IV groups) in an
experiment.
⩥ variable. Answer: factors that are kept constant or unchanging.
⩥ observation. Answer: The process of studying of something to gain
information.
⩥ inference. Answer: A conclusion made up of facts and inferring
knowledge.
⩥ conclusion. Answer: The final ending or idea of a process
⩥ prediction. Answer: A statement about the hypothesis
