Suppose you wish to be outstanding in your field by studyingplant cell biology. You discover a new strain of wild lima beanplants from Costa Rica that is resistant to being killed by ahydrophobic pesticide. Which one of the following states the mostreasonable hypothesis that could explain the nature of thepesticide resistance?
A) Many chloroplast proteins are encoded in the plant nucleargenome. A nuclear gene encoding an enzyme involved in the darkreactions might confer resistance by degrading the pesticide.
B) In the resistant strain, the plant cell wall might contain anovel phospholipid that binds to the pesticide and prevents itsentry into the plant cells.
C) The endoplasmic reticulum in the leaf cells of the resistantstrain might contain a mutant version of a cytochrome P450 enzymethat helps to remove the pesticide from the membrane.
D) The resistant strain has mutations in actin that inhibit thedevelopment of pluripotent cells in the stem, re. This results inactive transport of the pesticide via LDL particles interactingwith coated pits on the mitochondrial thylakoid membranes.
E) None of the above
