Justified the above statement with arguments and examples
Step by step
Solved in 2 steps
- What are the four phases of growth for an epidemic? Show these phases on a diagram. (Plant Pathology)It refer to the structures of the pathogen that are found associated with the infected plant (i,e., fungal mycelia, fruiting bodies, bacterial ooze, sclerotial bodies)Nicotine is a toxin in tobacco associated with “antibiosis” type of host plant resistance.
- Do you have any suggestions on how they could have controlled the spread of kudzu? As you stated in your post, the plant thrives in certain environmental conditions. Do you feel that certain environmental aspects can be purposely altered in an attempt to slow the progress of the plant? I was more interested in the kudzu plant as it has the ability to cause great harm, even to the extent of wiping out other plants and trees. Please explain the full bold information please. Thank youWhich of the following plant pathogens have had a large impact on civilization over the years? Claviceps purpurea Saccharomyces Phytophthora infestans All of the aboveis the relationship that both the microorganism and the host benefit. O Saprophytes Parasitism O Mutualism
- Difference between epidemic pathogen and virulent pathogen in Botany? With suitable exampleAgrobacterium tumefaciens carries a _______ that enters dicotyledonous (dicot) plant cells, transforming the cells into tumor cells and causing crown gall disease.Indicate which response would be most important for each pathogen attack. A fungus that can attack the roots, leaves, stems, and flowers of a plant Systemic acquired resistance Hypersensitive response A small colony of protists infects a leaf A localized bacterial infection in a single leaf After an initial pathogen attack, a second pathogen attacks several weeks later
- Consider the role of the tobacco industry in contributing to the global tobacco epidemic. Why is this industry sometimes described as a “disease vector” in promoting the epidemic? Support your answer. What in your opinion is the most effective strategy to combat the epidemic and reduce tobacco related disease and death? Justify your response.For fungal organism to be considered a "true" or "primary" pathogen it would need to be able to: Be completely nontreatable with antimicrobial agents Cause illness Invade an grow in a healthy, non-compromised host Be a member of the Candida genusBelow are statements about symbiosis. Choose the correct responses. ( Only pick one answer per [ ] ) ["Commensalism", "Mutualism", "Parasitism"] is a term that describes when two organisms both benefit from a relationship. One example of this you will view is lab is ["Viruses Infecting Bacteria", "Yeast Fermenting sugar", "Bacteria such as Rhizobium living in plant structures called root nodules"] . ["Commensalism", "Mutualism", "Parasitism"] is a term that describes when one organism benefits, while the second organism is not harmed, and does not benefit. ["Commensalism", "Mutualism", "Parasitism"] is a term that describes when one organism benefits while the second organism is harmed. In lab you will explore ["Viruses Infecting Bacteria", "Yeast Fermenting sugar", "Bacteria such as Rhizobium living in plant structures called root nodules"] as an example of this relationship.
