Question

A student keeps an onion bulb in a jar filled with water and observes that the roots continue to grow in length. The student cuts a root tip and observes it under a microscope. The image shows the observations. Which option supports the reason for an increase in the root’s length?The root cells undergo meiosis to expand and increase in length.

The root cells undergo mitosis to combine together to make the root grow.
The root cells undergo mitosis to form new identical cells.
The root cells undergo meiosis to form different types of cells.

Answer 1

The root cells undergo mitosis to form new identical cells.

Step-by-step explanation:

Mitosis is the process of cell division, where a cell divides into two equal cells with the same number of chromosomes. These new cells are used to promote the growth of a biological structure, promoting an elongation, a replacement, a concert, or an increase in volume. This can be seen in the case of the growth of the tip of the onion root, where the cells underwent mitosis, forming equal cells, to promote the growth of a new tip.
