Vadlapudi Mojess, G Mary Sandeepa

Cell is the structural and functional unit of life, in every living organisms are made from a cells. Every cell containing cytoplasm, nucleus and plasma membrane. A collection of cells is referred to as a tissues, on this review we will discussing plant and animal tissues. Plant tissues are majorly divided into meristematic and everlasting tissue, permanent (everlasting tissue) tissue again categorised into simple and complex tissue. Simple tissue (composed of single cell type) sub classified into dermis, parenchyma, collenchyma, sclerenchyma. Complex tissue (tissue composed of more than one cell type) sub-categorised into xylem and phloem, xylem vessels containing tracheids, phloem containing sieve tubes and companion cells, sieve tubes and RBC does not containing nucleus, ultimate all cells containing nucleus except sieve tubes and RBC. Animal tissues are classified into epithelial, connective, muscular and nervous tissues. Epithelial tissues classified into simple epithelium and compound epithelium, simple epithelium again classified into squamous, cuboidal, columnar, ciliated epithelium. Connective tissues categorised into loose connective tissue, dense connective tissue, specialised connective tissue. loose connective tissue containing areolar and adipose tissues, specialised connective tissue containing bone, cartilage, blood, lymph. Muscular tissue sub-classified into striated (skeletal), unstriated (easy), cardiac tissues. In this review provide detail information about these plant and animal tissues
