Question

how is the arrangement of cells in onion root tip?

Answer 1

An onion root tip is a rapidly growing part of the onion and thus many cells will be in different stages of mitosis. The onion root tips can be prepared and squashed in a way that allows them to be flattened on a microscopic slide, so that the chromosomes of individual cells can be observed easily.

Answer 2

The cell in an onion tip is rectangular in shape. Large numbers of cells are interlocked with each other. Each cell has a distinct wall which separates it from the surrounding cells. Each cell has a unique nucleus and large vacuoles at the center. Small granules maybe observed inside the cell.

Explanation:

The cell of onion divides very fast and the process is known as mitosis. In mitosis each cell divides into two daughter cells and resemble to the parent cell. It has four phases, Prophase, Metaphase, Anaphase and telophase.
