Tissue is a combination of similar cells that work together for a specific function, positioned between cells and organs in biological systems. Meristematic tissue is characterized by small, undifferentiated cells that continuously divide, featuring large nuclei and minimal vacuoles, as they focus on growth rather than waste storage. The two main types of plant tissue discussed are xylem, which transports water, and phloem, responsible for food transport.

- 1. What is a tissue? _____ What are some identifying features of meristematic tissue? Relative size of the cells: _____ Relative size of the nucleus: _____ Size of the vacuoles: Solution 4) when cells of similar type and same origin combine to perform a specific function it is known as tissue.it is a intermediate level between cells and organ.example: xylem and phloem.Xylem helps in the transportation of water throughout the plant and phloem helps in transportation of food to various parts of plants 5 ) (a)They are small in size.These cells are incompletely or not differentiated.They divide continuously.They are filled with protoplasm. (b) The relative size of nucleus is large.the cells forever remain young and throughout the life of plant.The main function is to perfrom mitosis. (c) vacoules are used to store waste material, excess salts etc.They are big and more in number in mature cells but meristemetic cells are mainly concern with growth hence they don't contain waste material so the size of their vacoule is small or they are absent in meristematic cells.
