Question

What are the three structural changes that must occur in young, unmodified plant cells as they develop into xylem tissue?

Answer 1

nothing just let them gain whatever neccesary for them

Answer 2

@sammychahal I think you misunderstood the question. The question is about cell differentiation, not human involvement in development of the xylem.

I would start this question by describing the structural characteristics of an undifferentiated cell, then go on to describe the xylem cell. I found this in the link below, but it might not be sufficient.

"Almost all plant cells produce primary cell walls. The major component of most primary walls in xylem is a disorganized network of cellulose fibrils, which allows the wall to stretch and expand as the cell grows. The secondary wall is deposited on the inner side of the primary wall during and after the cell has elongated or enlarged. The cellulose fibrils in the secondary wall are arranged in a regular fashion with alternating layers at fixed angles to the main axis of the cell. This reinforces the plant cell, while preserving the elastic nature of the primary wall. Most of the cell types in xylem can be distinguished based on the shape and features of the secondary cell wall."
