Ever wondered what makes your cells tick? Understanding cell structure is like getting the blueprint to life itself... Show more
Your body is built from eukaryotic cells - complex, organised structures packed with specialised parts called organelles. Unlike simple prokaryotic bacteria, these cells are like miniature cities with different departments handling specific tasks.
The plasma membrane acts as your cell's bouncer, controlling what gets in and out whilst responding to chemical signals like hormones. Plant cells get extra protection from a rigid cell wall made of cellulose that stops them from bursting under pressure.
At the heart of every cell sits the nucleus, your genetic control centre wrapped in a double-layered nuclear envelope with tiny pores. Inside, the nucleolus churns out ribosomes - the protein-making factories that either float freely or attach to the rough endoplasmic reticulum (RER).
The RER looks like stacked pancakes covered in ribosomes and specialises in folding proteins, while its smooth cousin (SER) handles lipid production. Vesicles act like delivery vans, shuttling materials between organelles and eventually reaching the Golgi apparatus - your cell's packaging and dispatch centre that also creates lysosomes filled with digestive enzymes.
Key Point Mitochondria are your cellular power stations, using a double membrane structure with folded inner layers (cristae) to produce ATP through aerobic respiration.
Making proteins is like following a recipe from your genetic cookbook. The process starts when DNA gets transcribed into mRNA in the nucleus, then travels through nuclear pores to ribosomes on the RER where the actual protein assembly happens.
Once built, proteins move through the RER's internal channels, get packaged into vesicles, and travel via microtubules to the Golgi apparatus for modifications. Finally, vesicles carry the finished products to the plasma membrane for release through exocytosis - a process crucial for hormones like insulin.
Prokaryotic cells (bacteria) are completely different beasts. They're tiny (2µm), have circular DNA floating freely, and cell walls made of peptidoglycan rather than cellulose. Their flagella are simple protein helixes, nothing like the complex 9+2 microtubule arrangement in eukaryotic cells.
Eukaryotic cells are giants in comparison with linear DNA safely tucked in a nucleus, membrane-bound organelles, and a sophisticated cytoskeleton made of microtubules and microfilaments that supports, shapes, and moves cellular components.
Remember The cytoskeleton isn't just structural - it's like your cell's internal motorway system, moving organelles and materials exactly where they need to go.
Light microscopes are your trusty workhorses - cheap, portable, and perfect for viewing living specimens up to 1500x magnification. However, their resolution maxes out at 0.2µm, meaning you'll struggle to see ribosomes or detailed organelle structures.
Laser scanning confocal microscopes create stunning 3D images by using fluorescent dyes that glow when hit with laser light. A pinhole blocks out unwanted light, producing incredibly detailed, coloured images perfect for medical research - though specimens must be dead.
Transmission electron microscopes (TEM) are the resolution champions, reaching 0.2nm and magnifying up to 2 million times. They fire electrons through ultra-thin specimens, creating detailed 2D black-and-white images where denser areas appear darker because they absorb more electrons.
Scanning electron microscopes (SEM) bounce electrons off specimen surfaces to create impressive 3D images at 200,000x magnification. Though resolution is lower than TEM (10nm), they're brilliant for studying surface structures and can even be enhanced with false colour.
Pro Tip Always calibrate your eyepiece graticule with a stage micrometer before measuring specimens - it's your key to accurate size calculations.
Getting perfect microscope images requires proper specimen preparation. Dehydrate your samples and embed them in wax to prevent distortion, then slice them thin enough for light to pass through effectively.
Staining is your secret weapon for highlighting specific structures. Acetic orcein turns chromosomes bright red, eosin colours cytoplasm, Sudan red reveals lipids, and iodine stains cell walls yellow whilst turning starch granules blue-black.
For measurements, line up your eyepiece graticule with the stage micrometer first. If one stage division (0.1mm) equals 4.5 eyepiece divisions, then each eyepiece division = 0.022mm. A specimen spanning 20 eyepiece divisions would measure 0.44mm.
Your total magnification is simple maths eyepiece magnification × objective lens magnification. Start with the lowest objective lens, raise the stage to maximum using the coarse adjustment, then fine-tune with the precision knob whilst looking through the eyepiece.
Essential Technique Always tilt your cover slip when placing it to avoid air bubbles - they'll ruin your image and make measurements impossible.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades
