Biology Year 10 Assessment Week

• Meristem tissue: Plant tissues containing undifferentiated stem cells
• Metabolism: All of the chemical reactions occurring in an organism.
• Non-communicable disease: A disease which cannot be spread between individuals.
• Organs: Aggregations of tissues performing specific functions.
• Organ systems: Groups of organs that work together to form organisms
• Protease: An enzyme produced in the stomach and pancreas that breaks proteins down into amino acids.
• Pulmonary artery: The main artery that takes deoxygenated blood away from the heart to the lungs.
• Pulmonary vein: The main vein that takes oxygenated blood back to the heart from the lungs.
• Rate of reaction: The speed at which reactants are converted into products
• Statins: A class of drugs that are used to reduce blood cholesterol levels which slows down the rate of fatty material deposit.
• Stent: A tube that can be surgically implanted into blood vessels to keep them open.
• Tissue: A group of cells with a similar structure and function.
• Vein: A blood vessel that carries blood at a low pressure back to the heart.
• Vena cava: The main vein that takes deoxygenated blood back to the heart from the body.
• Amylase: An enzyme produced in the salivary glands and pancreas that breaks carbohydrates down into simple sugars.
• Aorta: The main artery that takes oxygenated blood away from the heart to the body.
• Artery: A blood vessel that carries blood at high pressure away from the heart
• Bile: A substance made in the liver and stored in the gallbladder which is used to neutralise stomach acid in the intestine and emulsify fats.
• Blood: A tissue containing red blood cells, white blood cells, platelets and plasma
• Capillary: A very thin blood vessel that is used for exchange of substances.
• Cell: The basic building block of all living organisms.
• Communicable disease: A disease that can be spread between individuals either directly or indirectly.
• Coronary heart disease: A disease caused by the buildup of fatty deposits inside the coronary artery, narrowing it and reducing blood flow to the heart tissue.
• Enzymes: Biological catalysts that increase the rate of reactions in living organisms
• Health: The state of physical and mental wellbeing.
• Heart: An organ that pumps blood around the body in a double circulatory system.
• Lipase: An enzyme that is produced in the pancreas that breaks lipids down into fatty acids and glycerol.
• Lock and key hypothesis: A theory that describes how substrates must be the correct shape to fit the active site of an enzyme.
• Antibiotics: Medicines that help to cure bacterial disease by killing infective bacteria inside the body.
• Gonorrhoea: A sexually transmitted disease (STD) caused by a bacterium with symptoms of a thick yellow or green discharge from the vagina or penis and pain on urinating.
• Human Immunodeficiency Virus (HIV): An infectious virus that weakens the immune system and can lead to AIDS (acquired immunodeficiency syndrome).
• Communicable disease: A disease that can be spread between individuals either directly or indirectly.
• Malaria: A disease caused by a protist that causes recurrent episodes of fever and can be fatal.
• Measles: A serious disease caused by a virus that shows symptoms of fever and a red skin rash.
• Non-communicable disease: A disease which cannot be spread between individuals.
• Pathogens: Microorganisms that cause infectious disease.
• Salmonella: A bacterial disease that is spread by bacteria ingested in food and can cause a fever, abdominal cramps, vomiting and diarrhoea.
