Cells are the basic units of living things; they have specialised structures and functions (ACSSU149)

Elaborations
  • examining a variety of cells using a light microscope, by digital technology or by viewing a simulation
  • distinguishing plant cells from animal or fungal cells
  • identifying structures within cells and describing their function
  • recognising that some organisms consist of a single cell
  • recognising that cells reproduce via cell division
  • describing mitosis as cell division for growth and repair

Could you make a unicorn by crossing DNA?

Good question! Find out whether this is possible by watching as biologist at MIT, Dr Sera Thornton explains. What is a genome? And why do genomes need to be decoded? If the rhino genome was successfully decoded and the part that described the rhino horn was isolated, what would the process be for creating a unicorn?

How does the retina work?

When electrons in your retina absorb photons of light they don't emit light, they cause a molecule to change shape - and that lets you see colour!
