- You give a good overview of sexual and asexual reproduction in fungi. However, which one is more advantageous? and if one is more advantageous... why would the fungi use both types of replications? Again, your prompt is fair, but it is quite uncertain if you are telling which are favorable conditions and why... you do tell us that genetic variation is only possible under unfavorable circumstances. However, is this strategy due to evolution and fitness? or is it just because of circumstances given under the chance factor?arrow_forwardThe fungi in the photograph seem to be different individuals, can their DNA be identical? Explain.arrow_forwardSome fungi can be viewed as coenocytic organisms that exhibit little differentiation. When differentiation does occur, such as in the formation of reproductive structures, it is preceded by septum formation. Why does this occur?arrow_forward
- While working in a plant disease diagnostic lab, you receive a sample of a very dead tomato plant. The plant has rotted roots and the symptoms match known fungal and oomycete diseases of tomatoes. Explain one difference between true fungi and oomycetes that you could observe to determine what type of organism is killing the tomatoes?arrow_forwardThe ascomycete fungus that causes chestnut blight and has killed an estimated 4 billion chestnut trees in North America was accidentally imported from Asia. Why are plants particularly vulnerable to fungi imported from other regions? How do the plants in Asia protect themselves against ascomycete fungus so they are not affected?arrow_forwardA student is using a Venn Diagram to communicate understanding of the similarities and differences between fungi and animals. The student placed key characteristics in each circle and classmates are asked to review the work. A-You should remove ‘has a cell wall’ because neither fungi nor animals have a cell wall. B- You need to move the term heterotroph to the ‘animals’ circle because fungi can be heterotrophic or autotrophic.” C-“You have all of the information correct.” D- All animals only reproduce sexually so you need to move ‘may reproduce sexually or asexually ‘to fungi only.arrow_forward
- Fungi tend to reproduce sexually when nutrients are limited or other conditions are unfavorable, but they reproduce asexually in more ideal conditions. Why is this strategy successful? Need referencearrow_forwardDiscuss the economic importance of imperfect fungi.arrow_forward: See Figure 1 above. This picture of a yeast has been artificially colored green to help with viewing. What is potentially confusing about this color choice for a member of the fungi?arrow_forward
- In what ways (both positive and negative) are fungi important in modern biology and medicine?arrow_forwardMany fungi produce chemicals that inhibit bacterial growth. Why might the genes encoding these chemicals be adaptive to fungi?arrow_forwardSince dimorphism is a property of fungi, how do you account for thefact that molds grow preferentially in vitro rather than in vivo?arrow_forward
