What is the adaptive advantage of the filamentous nature of fungal mycelia?

What is the adaptive advantage of the filamentous nature of fungal mycelia?

The adaptive advantage associated with the filamentous nature of fungal mycelia is primarily related to: an extensive surface area well suited for invasive growth and absorptive nutrition.

What is the advantage of this characteristic to an organism that gets most of its nutrition through absorption?

What is the advantage of this to an organism that gets most of its nutrition through absorption? The larger surface area allows for more material to be transported through the cell membrane.

What feature of Chytrids supports the hypothesis that they represent an early fungal lineage?

What feature of the chytrids supports the hypothesis that they represent an early diverging fungal lineage? Chytrids have flagellated spores (zoospores) which would be necessary in early life due to the lack of a complex root structure and a water environment.

What is the major benefit of the extensive Dikaryotic stage found in ascomycota and basidiomycota?

What is the importance of the extended dikaryotic stage in the life cycles of basidiomycetes and ascomycetes? It allows for more genetic recombination.

What would be the adaptive advantage of a fungus producing and secreting a bacterial inhibitor?

Having a fungus that secreted a bacterial inhibitor would allow it to dominate the ecosystem with its fungi colonies. Bacteria and fungus typically grow in the same environment; therefore, having the ability to secrete a bacterial inhibitor would increase its ability to grow and have less competition.

What is the important difference between Ascospores and conidia?

What is the difference between ascospores and conidia? Ascospores are produce is a sexual process and have a ploidy of haploid while conidia is produced through an asexual phase.

Why is it advantageous for fungi to have an extremely high surface area to volume ratio?

Fungi have an extremely high surface-area-to-volume ratio. -This high ratio creates more room inside the cells for additional organelles involved in absorption. -This high ratio means that fungi have a thick, fleshy structure that allows the fungi to store more of the food it absorbs.

What are the filamentous mats formed by most fungi called?

Reproductive structure Hyphae • 3. Nearly all are multicellular = filamentous – Unicellular groups include yeasts and some chytrids. The vegetative bodies of most fungi are constructed of tiny filaments called hyphae that form an interwoven mat called a mycelium.

What is the adaptive advantage of mycelia?

The most important adaptive advantage associated with the filamentous nature of fungal mycelia is: an extensive surface area well suited for invasive growth and absorptive nutrition. In cases of non-resistant bacteria, antibiotics may relieve symptoms in a few weeks, but the infection has not been eliminated.

What is the evolutionary role of the Dikaryotic state in the fungi?

The prolonged dikaryotic stage is a feature unique to fungi. It is thought that the dikaryotic state provides the organism with genetic flexibility in a competitive environment while, at the same time, conferring it with many of the same advantages as a diploid because it possesses a complementary set of chromosomes.
