What type of tissue is composed of a single cell type?

Simple tissue is characterized by being composed of only one type of cell. This tissue type performs a variety of functions depending on the specific cell types present within it, such as photosynthesis, storage, and support. The primary examples of simple tissues include parenchyma, collenchyma, and sclerenchyma, each of which has distinct roles within plants.

In contrast, complex tissues, which are made up of multiple cell types working together, include xylem and phloem. Therefore, understanding that simple tissues comprise single cell types helps clarify their role in plant physiology and structure.
