Surface area to volume ratio diffusion experiment

An important concept to understand for the year 11 is diffusion. It wasn’t until I performed the surface area to volume ratio diffusion experiment that I understood the idea of diffusion. Essentially, if you imagine having a group of students packed in the corner of a classroom, give it time and they will spread outContinue reading “Surface area to volume ratio diffusion experiment”

Do prokaryotic cells differ from eukaryotic cells?

Maybe we can understand this as what is a cell supposed to do – yuck, a philosophical question. Perhaps then – how does it work?Continue reading “Do prokaryotic cells differ from eukaryotic cells?”

Electron Microscope for HSC Biology

An electron microscope lets you see the microscopic world. A world so small it can’t even be seen with light. They need to use electrons to visualise structures such as animal cells and virus’. There are two types of electron microscopes. Scanning electron microscopes (SEM) and transmission electron microscopes (TEM). Learn about the electron microscope.Continue reading “Electron Microscope for HSC Biology”
