How does Nancy Farmer use imagery in The House of the Scorpion?

Imagery:

"The cells were perfect- or so it seemed. Each was furnished with all it needed to grow. So much knowledge was hidden in that tiny world! Even Eduardo, who understood the process very well, was awed. The cell already understood what color hair it was to have, how tall it would become, and even whether it preferred spinach to broccoli. It might even have a hazy desire for music or crossword puzzles. All that was hidden in the droplet."

"I've been watching you, with your sharp little eyes. You take in everything everyone says. You're like the old man. I don't know much about this clone business- I was twelve the last time I darkened a schoolroom door- but I know you're a copy of him. It's like the old vulture was being given a second chance... I'll tell you this: El Patron has his good side and his bad side. Very dark indeed is his majesty when he wants to be. When he was young, he made a choice, like a tree does when it decides to grow one way or the other. He grew large and green until he shadowed over the whole forest, but most of his branches are twisted... I'm probably talking over your head, laddie. What I mean to say is this: When you're small, you can choose which way to grow. If you're kind and decent, you grow into a kind and decent man. If you're like El Patron... Just think about it."
