  • vascular bundles arranged in a ring in stem
  • main root with branching side roots
  • network of veins in leaves
30
Q

Characteristics of prokaryotic cells

A

No nucleus (instead a circular loop of DNA free in the cytoplasm), cell walls made of peptidoglycan, no mitochondria, often have plasmids

30
Q

How do protoctists feed?

A

Some feed by photosynthesis, others by organic substances made by other organisms

33
Q

Features of viruses

A

RNA, protein coat, antigens

34
Q

Virus infection sequence

A

Virus penetrates cell, releases genetic material, cell produces virus components, virus particles are assemnle, cell bursts, virus particles are relased, attach themselves to a new cell, the cycle repeats
