Question

The classification system developed in the early 1700s divided living organisms into plant and animals. Today, that has been expanded into five kingdoms.  What invention was most responsible for creating the need for the additional three kingdoms?

Ivy Acosta · Accepted Answer

Study of nucleus structures, number of cells in body, cell wall, chloroplasts etc., lead to further classification of organisms from two kingdoms to five kingdoms.

In the early seventeenth century, C. Linnaeus divided all living things into two major categories: plants and animals. However, after more in-depth research and discoveries about nucleus structures, the number of cells in an organism, the presence or absence of cell walls, chloroplasts, and other factors, organisms were further divided into the following five Kingdoms.

undefined The necessity for the extra three kingdoms was primarily caused by the development of the microscope.
