Tissues
Chapter 6 of the Class 9 NCERT Science textbook shows how cells organise into working teams. Meristematic tissues divide while permanent tissues, including parenchyma, collenchyma and sclerenchyma, support, store and strengthen plants. Xylem and phloem conduct water and food through the plant body. In animals, epithelial, connective, muscular and nervous tissues cover, bind, move and coordinate. Stained slides and everyday injuries connect microscopic structure with protection, movement and healing in living bodies.
