- Chemical Defenses: What is the benefit of having an inducible chemical defense, as opposed to a constitutive chemical defense? (an inducible defense is when the chemical is produced when herbivory is taking place as opposed to a constitutive defense where the chemical is always present) Inducible chemical defense best deters herbivory. With inducible defense predation will take place before a defense compound is produced which means there is damage to the plant before a defense is employed. With inducible defense herbivores are deterred even if no defense compound is produced. With inducible defenses energy is conserved by only producing secondary compounds when needed instead of continually. b 9 A....pdf XE A Week 9 Pre-lab.pdf A 10.7591 978150 A AY9_Week9_ng....xlsxChoose the one answer that fits best. Which of the following is NOT true with respect to plant defenses? O a. Plants are susceptible to infections by bacteria and fungi. O b. Some plant produce chemicals that inhibit the growth of other plant species. O c. Some plant produce pheromones to alert other members of the same species of the presence of herbivores. d. Some plants produce volatile chemicals with strong odors that are unpleasant to herbivores. e. All plants produce toxic chemicals to prevent infection from bacteria and fungi as well as to deter herbivores.Which of the following statements best describes what is depicted in the above image? The leaf in the image has most likely been infected by a parasitoid. The leaf in the image is an example of a plant defense known as mimicry. O The leaf in the image is depicting an exploitative interaction. The leaf in the image is an example of a plant defense known as allelopathy.
- Plant cells communicate in a variety of ways to elicit cellular responses. In the figure below the plant is responding the presence of light with the release of auxin. Auxin was first discovered for its ability to promote growth in plants. It is a plant hormone that inhibits the lengthening and stimulate the formation of lateral roots and root hairs. (c) Explain how the behavioral responses of the plant affect their overall fitness. ( refer to picture )Scientists studied changes in proline, which is an indicator of plant stress and overall protein content in the corn plant when leaves had been consumed by grasshoppers. Corn plants were exposed to varying numbers of grasshoppers and compared to control plants with no grasshopper exposure. The bar graphs, with error bars, show the mean proline and protein content. The dashed lines show the proline and protein content of healthy plants 10 days prior to treatment. Which of the following statements would most likely describe the growth of corn plants in this study? When there is a decrease in the number of grasshoppers (dependent variable) measured against proline and protein content (independent variables), the corn plants would have slower growth and be smaller than the control plants. When there is an increase in the number of grasshoppers (dependent variable) measured against proline and protein content (independent variables), the growth of the corn plants would be similar…Classify the plants based on the physical appearance of their defense structures. Classify them if they have the following ( If they have put description in each physical apperance, if they don't have put also some description each about it).a. with spinesb. with thornsc. with stinging trichomesd. with cutin or waxy leaves Plants to classify: stems of Euphorbia roses bunny ears cactus century plant makahiya kalamansi star apple leaves stinging nettle plant
- Create a carnivorous hypothetical plant incorporating physical, chemical, and behavioral defenses and its adaptations to biotic and abiotic stressors.emphasized how plastic and adaptable plants are in their environment. Write an essay touching on this concept. The first paragraph should be broad and discuss why plants must be more adaptable to their environment compared to other organisms, such as animals. Discuss if adaptation is or is not genetically determined and/or heritable. The second paragraph should provide a specific examples of how plants have adapted to stress. This portion needs to be in depth, and discuss both an abiotic and biotic stress.Plants have systemic defense mechanisms ( those that are not normally active but can be induced when the plant is under attack) describe an example of one systemic defense, including the processes, structures and/or molecules involved.
- Which of the following are examples of indirect chemical defenses? (Select all that apply). Extrafloral nectar Toxins Trichomes Compounds that make the plant taste bad Volatile organic compounds (VOCs)Explain why there are often trade-offs between plantgrowth and plant defense.Answer & Classify the plants based on the physical appearance of their defense structures. If they have the following defense structures explain. If they don't have make sure to provide some explanation to justify your answer. Thank you I hope you can answer it properly.
