Answer 1

Due to the missing diagram (Figure 1), it's not possible to definitively identify what structure 'Z' refers to based on the given options. Suppose the Z regions refer to a rod-like structure in the center of a cell visual; it would refer to a 'chromosome.'Please check the diagram and use this guidance to identify Z correctly. Referring to a well-labelled diagram of a cell undergoing mitosis might provide more accuracy and context.

Answer 2

## Step 1: Understanding the question.This question relates to knowledge of cell biology and needs an understanding of Cellular division or mitosis in plants, particularly an onion root tip. Specifically, we are asked to identify the labelled structure 'Z' in Figure 1 (which is not provided, unfortunately).
