Simple tissues in plants are composed of cells that are structurally and functionally similar, consisting of only one type of cell. Examples include parenchyma, collenchyma, and sclerenchyma. These tissues mostly provide functions such as storage, support, or photosynthesis. On the other hand, complex tissues are made up of more than one type of cells, differing in structure and function, and work together to perform tasks like transportation of water, minerals, and food. The main examples of complex tissues are xylem and phloem, which are involved in vascular functions in plants.

Key Differences

• Composition : Simple tissues have homogeneous cells (one cell type), while complex tissues have heterogeneous cells (multiple cell types).
• Function : Simple tissues mainly support, store, and perform photosynthesis; complex tissues primarily function in transport.
• Examples : Simple tissues include parenchyma, collenchyma, and sclerenchyma; complex tissues include xylem and phloem.
• Location : Simple tissues are found throughout the plant, while complex tissues are mainly in vascular regions.
