CELL BIOLOGY - GCSE Biology (AQA Topic B1)
Science Shorts・2 minutes read
Cells have intricate structures that can be viewed with electron microscopes, revealing details like DNA location and organelles in eukaryotic and prokaryotic cells. Cell processes like mitosis, diffusion, and osmosis can be studied through practical experiments showcasing concepts like cell duplication, molecule movement, and active transport methods in different environments and scenarios.
Insights
- Electron microscopes provide higher resolution than light microscopes, allowing for detailed visualization of subcellular structures and accurate measurement of cell size based on magnification.
- Bacteria reproduce through binary fission at a rapid rate, with experiments utilizing agar plates and aseptic techniques for growth studies, showcasing the importance of understanding cell division mechanisms in microbiology.
