Cell Structure and Function
Ever wondered what makes you "you" at the cellular level? Cell theory tells us that cells are the fundamental building blocks of all living things - pretty mind-blowing when you think about it!
Prokaryotic cells (like bacteria) are the simpler bunch. They've got 70s ribosomes floating freely to make proteins, and their DNA hangs out in a region called the nucleoid rather than being locked away in a nucleus. The capsule acts like a slippery protective coat that helps bacteria cause disease and avoid drying out.
Eukaryotic cells (plant and animal cells) are way more organised. Plant cells get some exclusive features like chloroplasts for photosynthesis, amyloplasts for storing starch, and a cell wall made of cellulose for support. They also have plasmodesmata - tiny channels that let neighbouring plant cells chat to each other.
Quick Tip: Remember that prokaryotic = "before nucleus" whilst eukaryotic = "true nucleus" - this'll help you remember which is which!
Organelles and Their Jobs
Your cells are basically tiny factories, and each organelle has its own specific job to keep things running smoothly. Think of it like a well-organised workplace where everyone knows their role.
The plasma membrane controls what gets in and out of the cell using its phospholipid bilayer structure. Meanwhile, the endoplasmic reticulum comes in two flavours: rough ER (covered in ribosomes) makes proteins, whilst smooth ER handles lipid production and transport.
The Golgi apparatus is like the cell's postal service - it modifies, packages, and ships proteins where they need to go. Mitochondria are your cellular power plants, churning out energy through respiration. Don't forget about lysosomes either - they're the cleanup crew that breaks down waste materials.
Remember: Ribosomes in eukaryotic cells are 80S (larger) compared to the 70S ribosomes in prokaryotes - this difference is often tested!
Gram Staining
When you need to identify bacteria quickly, Gram staining is your go-to technique. It's brilliantly simple and divides bacteria into two main groups based on their cell wall structure.
Gram-positive bacteria have thick peptidoglycan walls that trap the purple crystal violet stain, so they stay purple throughout the whole process. Gram-negative bacteria have thinner peptidoglycan walls, so the alcohol wash removes the purple stain, and they pick up the pink safranin counterstain instead.
This isn't just academic stuff - doctors use Gram staining in hospitals to quickly identify bacterial infections and choose the right antibiotics. The whole process takes minutes and can literally save lives.
Lab Hack: If you mess up the alcohol step, your results will be wrong - gram-negative bacteria might appear purple if you don't wash long enough!
Microscopy Basics
Light microscopes and electron microscopes are like comparing a decent camera to a professional film setup - both useful, but for different jobs. Your standard light microscope is perfect for looking at living cells and gives you lovely coloured images up to about 500x magnification.
Electron microscopes are the heavy hitters, magnifying up to 500,000x with incredible resolution. The downside? They kill your specimens and only produce black and white images. Plus, they're massively expensive and take up loads of space.
For calculations, remember: total magnification = objective lens power × eyepiece lens power. And get comfortable converting units: cm → mm (÷10) → μm (÷1000) → nm (÷1000).
Exam Tip: Questions often ask you to compare the two types - focus on magnification, resolution, living specimens, and cost as your key comparison points.
Specialised Cells
Cells aren't all the same boring blobs - they're actually incredibly specialised for their specific jobs. It's like how different professionals need different tools and skills.
Palisade mesophyll cells are packed with chloroplasts and positioned perfectly in leaves to catch maximum light for photosynthesis. Their thin cell walls and large vacuoles help maintain the right shape and pressure.
Sperm cells are built for one mission: reaching the egg. They've got a streamlined head with digestive enzymes, mitochondria-packed midpiece for energy, and a flagellum tail for swimming. Egg cells are the complete opposite - massive (relatively speaking), loaded with nutrients, and surrounded by protective layers.
Structure-Function Link: Always connect how a cell's structure helps it do its job - this relationship is exam gold!
More Specialised Cells and Tissues
Root hair cells are brilliant at their job - those long extensions massively increase surface area for absorbing water and minerals from soil. They're packed with mitochondria to power active transport when needed.
Red blood cells have that distinctive biconcave shape to maximise oxygen-carrying capacity. No nucleus means more room for haemoglobin, and their flexible membrane lets them squeeze through tiny capillaries. White blood cells are the body's security guards - they can change shape to engulf pathogens and are loaded with enzymes to destroy invaders.
Tissues are groups of similar cells working together. You've got four main types: epithelial (lining and protection), muscle (movement), nervous (communication), and connective (support and structure).
Real-World Connection: Understanding blood cells helps explain why altitude training works for athletes - more red blood cells mean better oxygen delivery!
Epithelial Tissues and Health
Epithelial tissues are basically your body's wallpaper and protective covering. Squamous epithelium lines blood vessels and air sacs in lungs - it's super thin for rapid gas exchange. Ciliated epithelium in your respiratory tract has tiny beating hairs that sweep mucus and trapped particles away from your lungs.
When things go wrong, you get conditions like emphysema, where alveoli walls break down, making breathing difficult. The endothelium lining blood vessels can get damaged by smoking, high blood pressure, or other factors.
Goblet cells produce mucus to trap pathogens and particles. White blood cells patrol these areas, ready to destroy any threats. It's like having a sophisticated security system throughout your body.
Health Link: Smoking damages ciliated epithelium, which is why smokers cough more - their natural cleaning system is broken!
Blood Vessels and Disease
Your blood vessels are like a sophisticated transport network. Arteries carry blood away from your heart and need thick, muscular walls to handle high pressure. Veins bring blood back and have thinner walls plus valves to prevent backflow. Capillaries are where the real action happens - their thin walls allow easy exchange of gases and nutrients.
Atherosclerosis is when arteries get clogged with fatty plaques containing cholesterol, calcium, and other substances. This narrows the arteries, increases blood pressure, and raises the risk of dangerous blood clots.
The consequences are serious: coronary heart disease, angina, heart attacks, and strokes. The process starts with damage to the endothelium, followed by inflammation and cholesterol buildup.
Prevention Point: Understanding atherosclerosis shows why diet and exercise matter - you're literally keeping your blood vessels healthy!
Muscle Tissue Structure
Muscle tissue is where the magic of movement happens. All muscle contains actin and myosin protein filaments that slide past each other to create contraction - it's like tiny molecular ropes pulling against each other.
Skeletal muscle has that striped appearance because of repeating bands of these proteins arranged in units called sarcomeres. Each muscle fibre contains loads of these sarcomeres, plus mitochondria for energy and specialised membranes for rapid communication.
The sliding filament mechanism works through a cycle: myosin heads bind to actin, pull (the power stroke), release, and repeat. ATP provides the energy for this process, and calcium ions control when it happens.
Movement Insight: Understanding muscle contraction explains why you need calcium in your diet and why ATP is so crucial for life!
Muscle Fibre Types
Not all muscle fibres are created equal - you've actually got two main types that serve completely different purposes. It's like having both a marathon runner and a sprinter in your muscles.
Slow-twitch fibres are the endurance specialists. They use aerobic respiration, are packed with mitochondria and blood vessels, and can work for ages without getting tired. Think marathon runners, long-distance cyclists, or just maintaining your posture all day.
Fast-twitch fibres are the power players. They rely on anaerobic respiration, have more myosin filaments, and store lots of glycogen and ATP for quick energy bursts. These handle sprinting, jumping, and explosive movements but tire quickly.
Athletic Application: Elite athletes often have specific ratios of these fibres based on their sport - sprinters have more fast-twitch, whilst endurance athletes have more slow-twitch!
