3.2 Microbes

Using ..........................., scientists saw tiny organisms wherever they looked

• telescopes

• microscopes

• gyroscopes

.........................................are living things, they are microscopic organisms that are too small to see without a microscope

• Plants

• Animals

• Micro-organisms or microbes

Uses light and lenses to magnify things

• Light microscope

• Electron microscopes

Can make things look up to 1000 times bigger.

• Light microscope

• Electron microscopes

The specimen observed needs to be thin enough to let light pass through it.

• Light microscope

• Electron microscopes

Can make things look up to one million times the size of the specimen.

• Light microscope

• Electron microscopes

Images from it are black and white but they can be coloured artificially to make them clearer

• Light microscope

• Electron microscopes

..............................., they show the surface of specimens

• SEMs (scanning electron microscopes)

• TEMs (transition electron microscopes)

..............................., they look through thin slices, like light microscopes do.

• SEMs (scanning electron microscopes)

• TEMs (transition electron microscopes)

They do not move.

• Algae

• Protozoa
