Tissue

• Tissue is a group of cells similar in structure
  and function.

Types of tissue

Plant tissue

Meristematic Tissue

• The growth of plants mainly occurred in certain
  specific regions due to dividing of tissue is
  also known as meristematic tissue.
• Meristematic tissue are classified as Apical,
  Lateral, Intercalary.
• Apical meristem is present at the growing of stem
  and roots increase the length of it. The girth of
  the stem or root increase due to lateral
  meristem. Lateral meristem is also known
  as(Cambium).Intercalary meristem is the
  meristematic the base of the leaves or internodes
  on twigs.

Permanent tissue

• When meristematic tissue formed cells they take
  up a specific role and lose the ability to divide
  and form the permanent tissue. The process of
  taking up a permanent shape, size and a function
  is called differentation.Cells of meristematic
  tissue differentiate to form different types of
  permanent tissue.
• Permanent tissue can be classified as Simple
  Permanent tissue and Complex permanent tissue.

Simple Permanent tissue

• It can be classified as Parenchyma,Collenchyma,Scl
  erenchyma

9
Complex Permanent Tissue

• Complex tissue are made of more than one type of
  tissue . It can be classified as Xylem and
  Phloem.
• Xylem-It consists tracheids , vessels , xylem
  parenchyma, xylem fibers .
• Phloem-It consists sieve tubes, Companion cells,
  Phloem fibers , Phloem Parenchyma.

Animal Tissue

• It can be classified in four types-Epithelial ,
  Connective ,Muscular ,Nervous .

• Nervous tissue is made up of neurons that receive
  and conduct impulses.
