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!
