Fungi are thought to be plyphyletic in that not all members are thought to have necessarily descended from a single common ancestor. Given this apparent fact, what is a "fungus" and what attributes or characteristics do most fungi share in common with one another. In other words, how would you know when looking at a particular organism that was a "fungus" and not something else, like a protozoan, plant, or an animal?

Expert Solution

Fungi are the multicellular eukaryotic organisms. They are heterotrophs and contains chitin in their cell wall. Another characteristic of fungi is hyphae, these are the tubular filaments found in fungi and their interwoven mass is known as "mycelium." The fungi can be readily distinguished from the bacteria due to their large size. All fungi are eukaryotes, while the bacteria are prokaryotes, they can be readily distinguished due to the large size of fungi.

Actinomycetes share some morphological features with the fungi, such as the hyphae, and spore formation. But, genetically actinomycete are different from fungi. Their GC (guanine and cytosine) content is lower than the fungus and higher than the bacteria. Due to this reason, the actinomycete are also known as gram-positive fungi.

In the past, fungi were thought to be plants. Explain why. Why are they no longer considered to be plants? What characteristics do fungi share with animals? What is the 3 – 4 letter root word of fungi? (Hint: what is the study of fungus?) Some fungi are pigmented. What is the purpose of the pigment? Fungi belong to what supergroup? If most fungi are nonmotile (do not move), why are they classified in that supergroup? What is the definition...

Endophytic fungi are required by gametophytes of all the "primitive" vascular plants. If the endophytic fungi is not present in the soil, the gametophyte plant will not grow. Why would such a condition develop? Are there any advantages to this absolute requirement for gametophyte development? Explain.

1. We know fungi are eukaryotic (have membrane-bound nucleus and organelles). Explain three unique ways fungi are different from other microbes (algae, protozoans, bacteria and archaea). Compare things like cell walls, cell membranes, morphology, reproduction, life cycles. 2. Algae and protozoans are loosely grouped together as protozoans and are different from plants because they lack certain characteristics of plants. Explain what differentiates algae from plants and two ways they are different from protozoans. Talk about algae being part of our...
