1 KEY WORDS: Structure Function Specialised Diffusion Osmosis ASSESSMENT: Sketch and label a plant and an animal cell; What do plant cells have that animal cells do not? What is the function of: Nucleus – Mitochondria Ribosomes Chloroplasts Cell Wall B2 REVISION – CHAPTER 1 – CELLS Draw and label 2 specialised cells. Explain their structure is adapted to suit their function Use pictures and words to describe the three ways substances can move in and out of cells Diffusion Osmosis Active Transport

2 KEY WORDS: Respiration Photosynthesis Limiting Factor Nitrates Magnesium ASSESSMENT: Why do plants need nitrates? Why do plants need magnesium? What is the equation for photosynthesis Where in the plant does it occur? How are leaves adapted to perform photosynthesis? B2 REVISION – CHAPTER 2 – HOW PLANTS PRODUCE FOOD Explain how light, CO 2 and temperature are limiting factors of photosynthesis Explain how plants use glucose for the following: Respiration Transport Storage

3 KEY WORDS: Biomass Decay Decomposer Carbon cycle Energy ASSESSMENT: What organisms break down matter? What conditions do they require? Why is the process of decay important? What is the main source of energy for living things? What is biomass and how does it change along a food chain? B2 REVISION – CHAPTER 3 – ENERGY FLOWS Describe how energy losses can be reduced in food production Explain how energy is lost in the following ways: Waste Movement Maintaining Body Temperature Describe the different forms carbon can be found in, how it is used, and how it is cycled

4 KEY WORDS: Enzyme Lock and Key Denature Aerobic respiration Bile Carbohydrase/Protease/Lipase ASSESSMENT: What is the equation for aerobic respiration? Where in the cell does it occur? Why do we need respiration? What are enzymes made from? What do enzymes do? How do they work? (explain & draw the lock & key mechanism B2 REVISION – CHAPTER 4 – ENZYMES What effect does temperature have on enzyme activity What effect does pH have on enzyme activity What are the 3 groups of enzymes in digestion? What is their substrate and what do they break them down into? 1) 2) 3) Why is the stomach acidic? What is bile, what does it do and how does it do it? Describe 3 industrial uses for enzymes

5 KEY WORDS: Homeostasis Thermoregulatory Centre Vasodilation/Vasoconstriction Insulin/Glucagon Glycogen Diabetes ASSESSMENT: What part of the brain controls body temperature? Explain how the body: a) Keeps Cool [e.g. how does sweating help?] b) Keeps warm What is homeostasis? Explain why the following are regulated: Waste products CO 2 Urea Water & ions B2 REVISION – CHAPTER 5 – HOMEOSTASIS How does the body control blood sugar levels? [Key Words: Insulin, Glucagon, Glycogen, Pancreas, Liver, Blood] What is diabetes? What are the symptoms? How can it be treated?

6 KEY WORDS: Chromosome Mitosis / Meiosis Gene Allele DNA Stem Cells ASSESSMENT: What are stem cells? State 2 uses of stem cells: State 2 problems with stem cell research: Chromosomes are made of long strands of what? Small sections of this are called what? What do genes code for? What is DNA fingerprinting? What is mitosis and why is it needed? What is differentiation? How does it differ in plants and animals? What is meiosis? Why is it important? How does it help generate variation? B2 REVISION – CHAPTER 6 – INHERITANCE How many chromosomes in a) gamete and b) somatic cell? What is an allele? What does a) dominant; and b) recessive mean? What is Huntington’s Disease and what causes it? What is Cystic Fibrosis and what causes it? On the back, cross 2 CF carriers and describe the offspring
