What are TISSUES?

• A tissue is a group of cells that are similar in
  structure and perform a specific function. There
  are two types of tissues, i.e., Plant tissue and
  Animal tissue. Plant tissues are further divided
  into two types, meristematic and permanent
  tissues. 
• On the basis of location of the meristematic
  tissue, it is divided into three types, i.e.,
  apical, intercalary and lateral meristem. 
• Permanent tissues are classified as simple and
  complex tissues. There are three types of simple
  tissues Parenchyma, collenchyma and
  sclerenchyma.
• There are two types of complex tissues, xylem and
  phloem. Xylem tissue is made of four kinds of
  cellular components s namely tracheids, vessels,
  xylem parenchyma and xylem fibres. While, phloem
  tissue consists of sieve tubes, companion cells,
  phloem parenchyma and phloem fibres.
• Animal tissues are classified as epithelial,
  connective, muscular and nervous tissue. On the
  basis of shape and function, epithelial tissue is
  classified as squamous, cuboidal, columnar,
  ciliated and glandular.
