Describe the T.S of Monocot stem.

The T.S of monocot stem has:

•  Epidermis 
•  Hypodermis
• Ground tissue 
•  Vascular bundles
  • Epidermis : It is the outermost protective layer.
    •  It is covered with a thin layer of cuticle.
    •  It consists of few stomata.
  • Hypodermis : It is present below the epidermis.
    •  It has sclerenchymatous tissue.
    •  It provide mechanical strength.
  • Ground tissue : A large, conspicuous parenchymatous ground tissue is present below the hypodermis.
  •  Vascular bundles : A large number of scattered vascular bundles present.
    •  Each vascular bundle is surrounded by a sclerenchymatous bundle sheath.
    •  Vascular bundles are conjoint and closed.
    •  Peripheral vascular bundles are generally smaller than the centrally located ones.
    •  The phloem parenchyma is absent.
    •  Water containing cavities (lysigenous cavities) are present within the vascular bundles.
