Plant tissue refers to groups of cells that work together to perform specific functions in plants. There are two main types of plant tissue: meristematic tissue, which is responsible for growth, and permanent tissue, which has specialized functions. Permanent tissue can be further divided into simple tissues, like parenchyma and collenchyma, and complex tissues, such as xylem and phloem. Xylem transports water and minerals from the roots to other parts of the plant, while phloem distributes sugars produced during photosynthesis. Together, these tissues support the plant's structure, facilitate growth, and enable essential processes for survival.
