AQA GCSE BIOLOGY HIGHER TIER PAPER
1H EXAMINATION TEST 2026 QUESTIONS
WITH SOLUTIONS
◉ Cell. Answer: The building blocks of all living organisms. Cells can
be prokaryotic or eukaryotic
◉ Eukaryote. Answer: Plant and Animal cells are eukaryotic cells as
they have a cell membrane, cytoplasm and a nucleus
◉ Prokaryote. Answer: Bacterial cells are prokaryotic cells as they are
very very small have a cell wall around their cell membrane and they do
not have a nucleus
◉ Cell Membrane. Answer: An envelope that surrounds the cell and lets
substances in and out
◉ Nucleus. Answer: Contains DNA and controls the cells activity
◉ Cytoplasm. Answer: The jelly centre of the cell which holds the sub-
cellular structures and is where all the chemical reactions happen
◉ Cell Wall. Answer: Only found in plant cells and bacterial cells. In
plant cells the cell wall is made of cellulose
, ◉ Single DNA Loop. Answer: In prokaryotic cells (bacteria) the DNA is
found as a single loop
◉ Plasmid. Answer: A small ring of DNA found in prokaryotic cells
(bacteria)
◉ Mitochondria. Answer: This is where respiration happens in cells
which gives the cells energy
◉ Chloroplasts. Answer: Only found in plant cells, these contain
chlorophyll and are the sites of photosynthesis and are green
◉ Ribosomes. Answer: Where proteins are made
◉ Vacuole. Answer: Found in plant cells, these contain cell sap which is
sugar and water
◉ Specialisation. Answer: When a cell becomes specialised for a
specific job. E.g. liver cells, heart cells, sperm cells.
◉ Organ. Answer: An organ is made up of different tissues and has a
specific job. E.g. the heart's job is to pump blood around the body.
◉ Organ System. Answer: An organ system contains more than one
organ working together. E.g. the cardiovascular system consists of the
heart, lungs and blood.
