Explanation / Answer

2. Fungi have been traditionally classified using morphology and reproductive mechanism.

Modern approach uses genetic analysis which has shown that traditional approaches are not correct in establishing taxonomic grouping.

3. Fungi contain chitin in their cell wall which is absent in plant cell wall. Instead of chitin, cellulose is present in plant cell wall.

4. The genus of fungi trichophyton causes many infections in humans associated with hairs, nails and skin.

5. Dimorphic refers to fungi that grow as yeast forms in tissues and reproduce by budding but produce mycelium and sporulating structures when grow in nutrient medium.

Histopllasma capsulatum is an example of dimorphic fungi.
