Write a dichotmous key to these 9 groups viroids viruses bac

Write a dichotmous key to these 9 groups: viroids, viruses, bacteria, prions, archaea, fungi, algae, protozoa, helminthes.

First choose characteristics that describe the groups - they don\'t have to be the same for all groups - just start with 3 characteristics. For example: Bacteria - living and made of cells, no nucleus, have peptidoglycan in cell walls.

Do that for all 9 - then start writing your key. How can you divide the 9 groups into 2 groups? That will be your first set of statements: 1. & 1., Once you have done that - then take the first half and continue to key them out. Then continue with the other half.

The first question is how can I divide these 9 groups of microbes into 2 different groups? Continue until you have a finished key

Solution

These 9 groups can be divided into two groups:

One group having Bacteria Virus Viroids and prions- mainly Prokaryotic organisms

Another group having Archaea and Eukaryotes
