Cells and Microscopy

Pages 16-20

Name five sub cellular structures that both plants and animal cells have

• Nucleus

• Cytoplasm

• Mitochondria

• Cell membrane

• Ribosomes

What three things do plant cells have but animal cells don’t?

• Cell wall

• Chloroplast

• Permanent vacuole

Where is the genetic material found in an animal cell?

The nucleus

Where is the genetic material found in a bacteria cell?

The single strand of DNA that floats freely in the cytoplasm

What type of organisms are bacteria - prokaryotes or eukaryotes?

Prokaryotes

Which has a higher resolution - a light microscope or an electron microscope?

Electron microscopes

How have electron microscopes increased our understanding of sub cellular structures?

They let us see much smaller things in more detail, like the internal structures of mitochondria and chloroplasts
