Why is onion root a good specimen for studying mitosis?

Two specimens are commonly used by biologists to study mitosis: the blastula of a whitefish and the root tip of an onion. … The onion root is also a good place because this is the area where the plant is growing. Remember that when cells divide, each new cell needs an exact copy of the DNA in the parent cell.

Why is an onion root tip good for studying mitosis?

Why is onion root tip used to demonstrate mitosis in this experiment? It is because of the meristematic cells that are situated in the tip of the roots that render the most desirable and suitable raw material to study the different stages of mitosis. Onion is a monocot plant. … Hence, their root tips are used.

Why is an onion root a good sample to view cells?

These regions of growth are good for studying the cell cycle because at any given time, you can find cells that are undergoing mitosis. In order to examine cells in the tip of an onion root, a thin slice of the root is placed onto a microscope slide and stained so the chromosomes will be visible.

What cells of an onion are good for studying mitosis?

Two specimens are commonly used by biologists to study mitosis: the blastula of a whitefish and the root tip of an onion. The whitefish embryo is a good place to look at mitosis because these cells are rapidly dividing as the fish embryo is growing.

What is the importance of mitosis in the root tips of plants?

The tissue region at the root needs to have very active dividing cells, especially at the very root tip, as to enable the root to grow in length. Therefore, various stages of mitosis can be observed at this region.

What phase do cells spend the least time in?

Anaphase is the shortest phase of mitosis. In anaphase, the sister chromatids are pulled apart to opposite ends of the cell. In metaphase, chromosomes line up along the metaphase plate. Metaphase takes a short amount of time to complete.

Why does a cell undergo mitosis?

Mitosis is a process where a single cell divides into two identical daughter cells (cell division). … The major purpose of mitosis is for growth and to replace worn out cells.

What would happen if mitosis were uncontrolled?

What would happen if mitosis were uncontrolled? The organism would likely produce tumorous growths that could become cancerous.

What characteristics of onion root tip allowed you to identify mitotic cells?

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.
