3. The diagram below represents a cell found in some complex organisms. The enlarged section represents an organelle, labeled X, found in this cell. Part A: Identity organelle X. State the process that this organelle performs.

Part B: Identify two materials that are needed for this process to occur, and then identify one molecule produced by this organelle and explain why it is important to the organism.
