Ready-made decks you can study right now, with spaced repetition built in so you review each card just before you would forget it. No account needed to start.
Eukaryotic and prokaryotic cells, subcellular structures, specialised cells and microscopy. Covers the cell structure section of AQA GCSE Biology Topic 1.
Chromosomes, the cell cycle, mitosis and stem cells, including therapeutic cloning and the arguments around embryonic stem cell use.
Diffusion, osmosis and active transport, surface area to volume ratio, and how exchange surfaces are adapted.
The microscopy, osmosis and culturing microorganisms practicals, plus the magnification and percentage change calculations that come with them.
How the body breaks food down and absorbs it: the organs of the digestive system, the role of bile, and what carbohydrates, proteins and lipids become.
Lock and key theory, denaturing, the three digestive enzymes, the four food tests, and the required practical on pH and amylase.
Double circulation, the structure of the heart, arteries veins and capillaries, the four components of blood, and treatments for coronary heart disease.
Communicable and non-communicable disease, risk factors and how they interact, correlation versus cause, and benign and malignant tumours.
Leaf structure, stomata and guard cells, xylem and phloem, transpiration and translocation, and the factors that change the rate of water loss.
Viruses, bacteria, protists and fungi, how they spread and how spread is reduced, plus the specific diseases named in the specification: measles, HIV, TMV, salmonella, gonorrhoea, rose black spot and malaria.
The body's non-specific barriers, what white blood cells actually do, and how vaccination produces immunity without causing the disease.
Why antibiotics do not work on viruses, how resistance develops, where digitalis, aspirin and penicillin came from, and how a new drug is tested before anyone can take it.
Detecting and identifying plant disease, ion deficiencies, and the physical, chemical and mechanical defences plants use. Biology only content.
The equation and what it means, why photosynthesis is endothermic, where the raw materials come from, and the five things a plant does with the glucose it makes.
Light intensity, carbon dioxide, temperature and chlorophyll as limiting factors, reading rate graphs, the inverse square law, and the required practical with pondweed.
Aerobic and anaerobic respiration, fermentation in yeast, what happens to the body during exercise, lactic acid and oxygen debt.
What metabolism means, the reactions that build and break down molecules in the body, and how the liver deals with lactic acid and excess protein.
What homeostasis is and why it matters, receptors coordination centres and effectors, the reflex arc, and the required practical on reaction time.
Regions of the brain and why treating it is difficult, the structure of the eye, accommodation, long and short sightedness, and how body temperature is controlled. Biology only content.
The endocrine system and the main glands, how insulin and glucagon control blood glucose, and the difference between type 1 and type 2 diabetes.
How the body loses water, filtration and selective reabsorption, the role of ADH, and how dialysis compares with a kidney transplant. Biology only content.
Sexual and asexual reproduction and when each is an advantage, what meiosis does and how it differs from mitosis, and organisms that use both.
The structure of DNA, the four bases and how they pair, transcription and translation, and what mutations do. Mostly Biology only content.
Alleles, dominant and recessive, genotype and phenotype, working out crosses with Punnett squares and family trees, and how sex is determined.
Polydactyly and cystic fibrosis, how carriers pass conditions on, and the arguments for and against embryo screening.
What organisms compete for, abiotic and biotic factors, structural behavioural and functional adaptations, extremophiles, and why communities depend on each other.
Levels of organisation from individual to ecosystem, food chains and predator prey cycles, and the required practical using quadrats and transects.
The water cycle and the carbon cycle, the role of decomposers, what affects the rate of decay, and how compost and biogas make use of it.
Why biodiversity matters, pollution of land water and air, deforestation and peat destruction, global warming and its effects, and programmes to protect species.
How monoclonal antibodies are produced from hybridoma cells, and their uses in pregnancy tests, diagnosis and treatment. Biology only content.
Puberty and the menstrual cycle, the four hormones that control it, methods of contraception, and fertility treatment including IVF.
Where variation comes from, Darwin and Wallace, speciation, evidence from fossils, extinction, and antibiotic resistant bacteria as evolution you can watch.
Trophic levels and pyramids of biomass, why so little biomass is transferred between levels, threats to food security, and sustainable farming and fishing. Biology only content.
