Tissue: A group of cells which are similar in structure, function & origin and together they perform a particular function is called a tissue. Tissue is divided into two groups on the basis of cell wall- Plant Tissue & Animal Tissue. Plant Tissue: Plants are made up of various types of cell which come together to form Tissue. Further plant tissues ate divided in two groups on the basis of their dividing capability i.e. Meristematic Tissue ( Dividing tissue ) & Permanent Tissue ( Non-dividing tissue ). Meristematic tissues convert to Permanent Tissue by the process of Differentiation. Differentiation is the process of taking fixed shape, size, function of cells. Meristematic Tissue: The growing or dividing tissues are called Meristematic tissue. This tissue is very active, dense cytoplasm, thin cell wall, prominent nuclei and they lack vacoules due to fast division purpose. This tissue is also divided into three types on the basis of their location. A...
