question:  What is the last step Captain Hannah must conduct in order to deliver successfully fruited plants to Gloryanna. What is the symbolic significance of this?
context: Captain Hannah climbed painfully down from the Delta Crucis , hobbled across the spaceport to where Beulah and I were waiting to greet him and hit me in the eye. Transshipped seeds invariably failed to germinate, which explained its rarity. But when I offered them a sizable piece of cash plus a perpetual share of the profits for letting us take a load of marocca plants to Gloryanna III, they relented and, for the first time in history, gave their assent. If we had gone through all of that rigamarole, we would have lost the franchise. And by the time I had lined up for Gloryanna and Jumped, I figured, like you said, that the trip would be a cakewalk. They 'remember' the rate and direction of movement, and keep it up during the night time. So I lined up the Delta Crucis perpendicular to her direction of motion, put a once-every-twenty-one hour spin on her to match the rotation rates of Mypore II and Gloryanna III, and uncovered the view ports to let in the light. It gradually brightened until 'noon time', with the ports pointing straight at the light source, and then dimmed until we had ten and one-half hours of darkness. "Oh," said Captain Hannah in quiet tones of controlled desperation, "it was very simple. "Of course, first I had to move all the hydroponic tanks from their original positions perpendicular to the axial thrust line of the ship to a radial position. And because somehow we had picked up half of the plants in the northern hemisphere of Mypore and the other half in the southern hemisphere, it turned out that half of the plants had a sinistral corkscrew and the other half had a dextral. So I had to set the plants up in two different rooms, and run an artificial sun for each, going clockwise with one, widdershins with the other.
output:  Captain Hannah must feed the marocca cuttings from their vines, but only after mulching them through an organic processor. His body turns out to be the only processor on board, meaning Captain Hannah must eat and process the vine clippings with his own body. This symbolizes the kind of will the plants’ have  over Hannah—they have inconvenienced him to the extent of his own insides.
options:  Captain Hannah must simulate proper sun exposure in order to ensure the plants’ vines don’t die. Their death would mean no fruit, symbolizing the way in which Hannah’s failure to keep the vines alive is the last possible way in which the narrator’s plan could fail.  Captain Hannah must exterminate all of the spores and bugs before reaching Gloryanna, seeing as the Gloryannans will only accept marocca fruit alone for fear of reinfecting their planet with its spores. It is symbolic that Hannah cannot sell the objects which make the fruit, but only the fruit alone.
