Kingdom Fungi, rhizopus, mold (A-biology)

Kingdom Fungi

Specific Objectives

The learner should be able to:

1. State the characteristic of fungi
2. State characteristics of Rhizopus or Mucor, yeast, and mushroom.
3. State the economic importance of fungi
4. Name the common fungal diseases
5. Describe the method of preventing fungal diseases
6. Explain the use of yeast in brewing alcohol and bread making

Characteristics

1. Have no chlorophyll; do not photosynthesize.
2. Heterotrophic
3. Cell wall contains chitin rather than cellulose
4. The body usually a mycelium
5. Carbohydrates stored as glycogen
6. Reproduction by means of spores without flagella

Classification

Phylum: Zygomycota	Phylum: Ascomycota	Phylum: Basidiomycota
No septa in hyphae; large branched mycelium formed	Septa in hyphae	Septa in hyphae, large 3-dimensional structure often formed
Asexual reproduction by sporangia producing spores or y conidia	Asexual reproduction by conidia	Asexual reproduction unusual but by spores
Sexual reproduction by  conjugation that gives rise to zygospore	Sexual reproduction by ascospores forming in an ascus	Sexual reproduction by the formation of basididiospores outside basidia
Example: mold or Mucor Rhizopus- bread mold	e.g., yeast	E.g. Agaricus Campestris -field mushroom

 

Economic importance of fungi

Beneficial

1. Decompose and recycle organic matter
2. Production of antibiotics e.g. penicillin
3. Production of alcohols
4. Baking e.g. yeast

Nonbeneficial

1. Cause diseases e.g. ringworm,
2. Food decay

Example fungal disease in plants

Anthracnose;

1. Rots;
2. Mildews
3. Rusts

Example of fungal diseases to animals

1. Athletic foot
2. Ringworm
3. Candida
4. meningitis
