Cell Structure and Types
Your body is made up of eukaryotic cells, which are complex structures packed with specialised parts called organelles. Both animal and plant cells fall into this category, but they've got some key differences you need to know.
Animal cells contain essential organelles like the nucleus (which holds your DNA and controls the cell), mitochondria (the powerhouses that provide energy), ribosomes (protein factories), and cytoplasm (where chemical reactions happen). The cell membrane acts like a bouncer, deciding what gets in and out.
Plant cells have all the same bits as animal cells, plus some extras. They've got a tough cell wall made of cellulose for structure, chloroplasts for photosynthesis (that's why plants are green!), and a large vacuole for storing cell sap and waste products.
Quick Tip: Remember that prokaryotic cells like bacteria are much simpler and smaller - they don't have a proper nucleus or organised organelles like eukaryotic cells do.
