13 Questions
What are the main components of a plant's body?
roots, shoots, and leaves
What is the nature of most fungi cells?
Most fungi cells are haploid by nature.
Plants utilize closed mitosis for cell division
False
What type of mitosis do fungi utilize?
closed mitosis
What is the composition of a fungi's body?
Their body consists of interwoven hyphae (filamentous cells).
Fungi have cell walls composed of chitin and other polysaccharides
True
Plants are chemoheterotrophs and do not have chlorophyll
False
How do fungi absorb organic molecules?
Fungi secretes digestive enzymes into the surrounding environment, and absorbs organic molecules across the body wall.
What are the main components of a fungi's cell wall?
chitin and other polysaccharides
What is the primary mode of reproduction for fungi?
Reproduction is primarily via the production of spores, which are dispersed by wind or animals.
What are the characteristics of Phylum Basidiomycota?
Phylum Basidiomycota includes mushrooms, shelf fungi, rusts, smuts, etc., and reproduces sexually via plasmogamy of +/- types and the forming of dikaryotic hyphae, which forms the fruiting body (basidiocarp).
What is the defining characteristic of imperfect fungi?
Imperfect fungi are defined as such because sexual reproductive stages have not been observed, and they reproduce via parasexuality.
What are some examples of imperfect fungi?
Examples of imperfect fungi include Penicillium and Aspergillus.
Study Notes
The World of Fungi
- Fungi are chemoheterotrophs without chlorophyll, and their body consists of interwoven hyphae (filamentous cells).
- The Kingdom Fungi has 120,000+ described species in 20 different phyla, and they may be unicellular or multicellular, terrestrial or aquatic, pathogenic for plants or people, predaceous, or bioluminescent.
- Mycelium, composed of interwoven hyphae, grows through and penetrates its substrate, secretes digestive enzymes into the surrounding environment, and absorbs organic molecules across the body wall.
- Most fungi cells are haploid by nature, and instead of separate sexes, there are “+ type” and “- type” versions.
- Reproduction is primarily via the production of spores, which are dispersed by wind or animals.
- Phylum Zygomycota includes common bread molds and reproduces asexually with the production of spores within sporangia at the tip of erect stalks called sporangiophores.
- Phylum Basidiomycota includes mushrooms, shelf fungi, rusts, smuts, etc., and reproduces sexually via plasmogamy of +/- types and the forming of dikaryotic hyphae, which forms the fruiting body (basidiocarp).
- Imperfect fungi are defined as such because sexual reproductive stages have not been observed, and they reproduce via parasexuality.
- Examples of imperfect fungi include Penicillium and Aspergillus.
