The herbicide glyphosate (Roundup®) kills plants by inhibiting an enzyme needed forsynthesis of phenylalanine. Deprived of phenylalanine, the plant cannot make the proteinsit needs, and it gradually weakens and dies. Although a small amount of glyphosate isdeadly to a plant, its human toxicity is quite low. Suggest why this powerful herbicidehas little effect on humans.

Glyphosate is an herbicide used to kill weeds. It is themain component of a product made by the MonsantoCompany called Roundup. Glyphosate kills plants by inhibiting an enzyme in the shikimate pathway calledEPSPS. This herbicide is considered safe because animalsdo not have the shikimate pathway. To sell even more oftheir herbicide, Monsanto commissioned its plant geneticists to engineer several crop plants, including corn, to beresistant to glyphosate. To do so, the scientists had to introduce an EPSPS enzyme that was resistant to inhibitionby glyphosate into crop plants and then test the transformed plants for resistance to the herbicide.Imagine that you are one of these scientists and thatyou have managed to successfully introduce the resistant EPSPS gene into the corn chromosomes. Youfind that some of the transgenic plants are resistant tothe herbicide, whereas others are not. Your supervisoris very upset and demands an explanation of why someof the plants are not resistant even…

) Both the caterpillar stage of the yucca moth and the ground sloth ate seeds of the yucca plant. However, when caterpillars eat, they completely digest the seed itself. When sloths ate the seeds, the seeds passed intact through the digestive system. How would you classify each of these interactions for the plant (positive or negative)? What do these interactions tell you about plant and animal interactions involving part of the plant being eaten?
