7. Archaega does not have cell wall but they do compose of peptidoglycan molecules with the exception of methanobacteria who have pseudo peptidoglycan in their cell wall. 8. There are three main types of archaea: the crenarchaeota which are characterized by their ability to tolerate extremes in temperature and acidity. The euryarchaeota which include methane-producers and salt-lovers; and the korarchaeota catch-all group for archaeans about which very little is known.
Many bacteria are parasitic on external and internal body surfaces; some of these invade the inner tissues and cause disease. Most parasites are obligate; i.e., they are unable to

Some fungi have beneficial uses. For example, penicillin and yeast for baking. Thrush is a common fungal infection. Parasites are small organisms which depend can only live on a host. Plants, animals, humans, fish, birds and reptiles can all be host to parasites.
1) Bacteria are living things that are neither plants nor animals, but belong to a group all by themselves. They are very small, individually not more than one single cell. However there are normally millions of them together, for they can multiply really fast. Bacteria are prokaryotes (single cells that do not contain a nucleus). They are ten to 100 times larger than viruses.
