how are simple tissue different from complex tissue in plants

Simple tissues in plants are made up of only one type of cell that looks alike and performs similar functions, whereas complex tissues consist of various cell types that work together to perform multiple functions. Simple tissues include parenchyma, collenchyma, and sclerenchyma, mainly involved in photosynthesis, storage, and support. Complex tissues include xylem and phloem and are primarily responsible for the transport of water, nutrients, and food within the plant. Simple tissue cells are loosely packed, while complex tissue cells have a more organized structure with specialized cells such as vessel elements and sieve tube elements, predominantly found in vascular tissues.
