Simple tissues are composed of a single type of cell that performs a uniform function, while complex tissues consist of multiple types of cells working together to perform specialized and integrated functions. Simple tissues are homogeneous and involved mainly in storage, support, and photosynthesis, present throughout the plant. Complex tissues are heterogeneous, forming vascular tissues like xylem and phloem, and are responsible for the transport of water, nutrients, and food in plants.

Key Differences:

• Cell Composition : Simple tissues have one cell type; complex tissues have multiple cell types.
• Function : Simple tissues focus on storage, support, and sometimes photosynthesis; complex tissues specialize in transportation.
• Location : Simple tissues are found throughout the plant; complex tissues are mainly found in vascular regions.
• Examples : Simple tissues include parenchyma, collenchyma, and sclerenchyma; complex tissues include xylem and phloem.

These differences highlight the structural and functional distinctions between simple and complex tissues in plants.
