Question

an example of mitosis at work is a plant root elongating. absorbing. pointing down. breaking.

Explanation:

Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus. In plants, mitosis in the root meristem (region of active cell division) leads to cell proliferation. As new cells are formed through mitosis and then elongate (due to processes like cell - wall loosening and water uptake), the root elongates. Absorbing (related to function of root hairs for water and nutrient uptake), pointing down (due to gravitropism - a growth response to gravity, not directly mitosis), and breaking (a physical damage - related event) are not direct results of mitosis at work in the context of normal root growth.

Answer:

elongating.
