Microscopy and Calculations
Getting comfortable with microscopes is easier than you think - just remember to always start on the lowest magnification before working your way up. Use the coarse focus knob first, then switch to fine focus for crystal-clear images of cells.
The magnification formula is your best friend: magnification = image size ÷ real size. Don't forget that magnification also equals eyepiece × objective lens. When dealing with measurements, always convert units carefully - micrometers (µm) are commonly used for cell measurements.
For any experiment, you'll need to calculate percentage change using: % change = (change ÷ original) × 100. Uncertainty is simply the range divided by 2, which helps you understand how reliable your measurements are.
Quick Tip: When converting from millimetres to micrometers, multiply by 1000 - this catches out loads of students in exams!
Osmosis and Food Tests
Osmosis is just water moving from where there's lots of it (dilute solution) to where there's less of it (concentrated solution). Think of it like water always trying to balance things out. In experiments, you'll typically change the sugar concentration and measure mass changes in potato chips.
Food tests are actually quite satisfying once you know the colour changes. Starch turns iodine from orange to black, sugars turn Benedict's solution from blue to orange when heated, and proteins turn Biuret reagent from blue to purple.
Enzymes work like a lock and key system - the substrate fits perfectly into the active site. Amylase breaks down starch into sugars, and you can test this by checking when iodine stays orange (meaning no starch left). Temperature and pH massively affect how well enzymes work.
Remember: Always crush your food samples with a pestle and mortar, then mix with water before testing - this gives you much clearer results.
Photosynthesis and Data Analysis
Surface area to volume ratio gets smaller as objects get bigger - a 1cm cube has a 6:1 ratio, but a 3cm cube only has 2:1. This is crucial for understanding how cells exchange materials efficiently.
In photosynthesis experiments, you'll often count oxygen bubbles from pondweed at different distances from a lamp. Keep everything else constant - temperature, lamp power, and pondweed type - or your results won't mean anything.
Data analysis is straightforward once you know the rules. The mean (average) involves adding all values and dividing by how many there are. The median is the middle value when you arrange numbers in order. The mode is simply whichever number appears most often.
Exam Hack: When calculating uncertainty, remember it's just range ÷ 2 - this formula appears in loads of practical questions.
Cell Biology and Division
Prokaryotic cells (like bacteria) are the simple ones without a nucleus - their DNA just floats around freely. Eukaryotic cells (like yours) have a proper nucleus and mitochondria to keep everything organised.
Plant cells are basically animal cells with extras: a cell wall for support, chloroplasts for photosynthesis, and a large vacuole for storage. Bacterial cells sometimes have a plasmid (ring of DNA) and a flagellum for swimming about.
Mitosis is how one cell becomes two identical cells, each with 46 chromosomes. The cell grows, copies its DNA, then divides. Stem cells are special because they can turn into any type of cell - that's why they're so important for medical research.
Key Point: Anything that starts and ends with the same number of chromosomes (46 → 46, 46) involves mitosis - this helps you spot it in exam questions.
Transport in Cells
Diffusion is particles moving from high to low concentration - like perfume spreading across a room. The bigger the concentration gradient (difference in concentration), the faster diffusion happens.
Exchange surfaces like alveoli, fish gills, and villi all have one thing in common - massive surface area. Alveoli let oxygen into your blood, gills help fish extract oxygen from water, and villi absorb nutrients in your small intestine.
Active transport is different because it needs energy and goes against the concentration gradient. While osmosis moves water from dilute to concentrated solutions, active transport can pump substances the 'wrong' way using energy from mitochondria.
Memory Trick: Active transport is like swimming upstream - it needs energy to go against the natural flow, just like particles moving against their concentration gradient.
Plant Transport and Photosynthesis
Xylem vessels are like plant plumbing - they're dead, hollow cells strengthened with lignin that transport water upwards. Transpiration is water loss from leaves, and it speeds up with higher temperature, more light, less humidity, or increased air flow.
Leaves are perfectly designed for photosynthesis: carbon dioxide + water → glucose + oxygen. Palisade cells packed with chloroplasts do most of the work, while spongy mesophyll has air gaps for gas exchange.
Stomata (controlled by guard cells) are like tiny doors that open and close to control gas exchange and water loss. Limiting factors for photosynthesis include light intensity, CO₂ concentration, and temperature - whichever is in shortest supply limits the rate.
Exam Focus: Learn the photosynthesis equation off by heart - it appears in multiple question types and you'll lose easy marks if you get it wrong.
Glucose Use and Respiration
Plants don't just make glucose through photosynthesis - they actually use it in five main ways: respiration for energy, storage as starch (like in potatoes), conversion to lipids, making cellulose for cell walls, and creating amino acids for proteins (which needs nitrates from soil).
Phloem vessels transport sugars in both directions using translocation. Unlike xylem, these are living cells with pores between them, creating a two-way sugar highway throughout the plant.
Aerobic respiration uses oxygen: glucose + oxygen → carbon dioxide + water + energy. When oxygen runs out, anaerobic respiration kicks in - animals produce lactic acid, while plants and yeast make ethanol and carbon dioxide (perfect for bread and alcohol production).
Real-World Connection: Yeast's anaerobic respiration is why bread rises and how alcoholic drinks are made - it's the same biological process with different practical applications.
Heart, Blood, and Breathing
Your heart has four chambers with the left side being more muscular because it pumps blood around your entire body. The pacemaker keeps everything in rhythm, while the pulmonary artery and vein handle lung circulation.
Arteries have thick, muscular walls with elastic fibres for high-pressure blood flow. Veins have thinner walls, valves, and larger lumens for low-pressure return flow. Capillaries are tiny vessels where actual gas exchange happens.
During exercise, your heart rate and breathing rate increase to get more oxygen to muscles for respiration. This releases extra energy needed for muscle contraction. Your lungs work through the trachea, bronchi, and alveoli to maximise gas exchange.
Helpful Hint: Remember that pulmonary vessels are the odd ones out - the pulmonary artery carries deoxygenated blood (to lungs) while the pulmonary vein carries oxygenated blood (from lungs).
Digestion and Blood
Digestion involves three main enzymes: amylase (breaks starch into sugars), protease (breaks proteins into amino acids), and lipase (breaks lipids into fatty acids and glycerol). All three are made in the pancreas and work in the small intestine.
Bile is stored in the gall bladder and does two important jobs - it neutralises stomach acid and emulsifies fats, increasing surface area so lipase can work more effectively. The digestive system changes from acidic (stomach) to alkaline (small intestine).
Your blood contains red blood cells with haemoglobin for oxygen transport, white blood cells that fight disease, platelets for clotting, and plasma that carries everything around. Vaccines work by introducing dead or weakened pathogens so your immune system can recognise them later.
Exam Tip: Remember that emulsification isn't digestion - bile breaks fat into smaller droplets but doesn't change the chemical structure like enzymes do.
Disease and Health
Non-communicable diseases like cancer and cardiovascular disease aren't passed between people. Tumours can be benign or malignant (cancerous and spreading). Risk factors include smoking, alcohol, obesity, and high fat/salt diets.
Communicable diseases are caused by pathogens - microorganisms spread through water, air, or direct contact. Bacteria are prokaryotic cells that release toxins and replicate rapidly. Viruses are smaller, non-living particles that replicate inside cells and burst out.
Protists are single-celled eukaryotes, often parasites carried by vectors (like mosquitoes carrying malaria). Fungi have thread-like structures called hyphae and reproduce using spores. Each pathogen type requires different treatment approaches.
Key Distinction: Bacteria are living cells you can treat with antibiotics, but viruses aren't truly alive and need antiviral drugs or vaccines for prevention.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
