with the help of a labelled diagram describe the structure of a typical anatropous ovule.

Dear Student, 

The ovule is the structure that gives rise to and contains the female reproductive cells.
Structure of an anatropous ovule is as follows:​​​​​​
  • Chalaza: It is the basal swollen part of the nucellus from where the integuments originates
  • Nucellus: The embryo sac is located inside the nucellus. It provides nutrition to the developing embryo. Its parenchymatous tissue surrounded by the integuments from the outside.
  • Integuments: These are the outer layers which surrounds the ovule. It provide protection to the developing embryo. 
  • Micropyle:  It is the point where the pollen tube enters the ovule at the time of fertilization.
  • Hilum: It is the point where the body of the ovule is attached to the funiculus.
  • Funiculus: It is a stalk-like structure which represents the point of attachment of the ovule to the placenta of the ovary.




Regards.

Answer:-) The structure of a typical anatropous ovule



The various parts of an ovule are :–
  • Funicle : It is a stalk-like structure which represents the point of attachment of the ovule to the placenta of the ovary.
  • Hilum : It is the point where the body of the ovule is attached to the funiculus.
  • Integuments : They are the outer layers surrounding the ovule that provide protection to the developing embryo.
  • Micropyle : It is a narrow pore formed by the projection of integuments. It marks the point where the pollen tube enters the ovule at the time of fertilization.
  • Nucellus : It is a mass of the parenchymatous tissue surrounded by the integuments from the outside. The nucellus provides nutrition to the developing embryo. The embryo sac is located inside the nucellus.
  • Chalazal : It is the based swollen part of the nucellus from where the integuments originate.
