Hello. This question is incomplete. The full question is:
Explain why Bud says that "It's funny how ideas are, in a lot of ways they're just like seeds. Both of them start real small and then ... Woop, zoop, sloop ... Before you can say Jack Robinson they've gone and grown a lot bigger than you ever thought they could"
Answer:
Bud says this to show how a small and insignificant idea became something big inside him, becoming his biggest goal.
Explanation:
Bud explains that the idea of looking for and finding his father was insignificant, small in his subconscious and that he could go unnoticed by other more important and impacting ideas, however, over time, that idea grew and grew until he became the biggest goal of his life. To better explain it to the reader, he makes reference to how a seed so small can become such a large and imposing tree. The seed symbolizes the idea and the tree symbolizes the goal.
Volume should be the answer
Answer: Symbolism takes something that is usually concrete and associates or affixes it to something else in order to give it a new and more significant meaning.
