a) Draw a L.S. of a pistil showing pollen tube entering the embryo-sac in an angiosperm and label any six parts other than stigma, and ovary. b) Write the changes a fertilized ovule undergoes within the ovary in an angiosperm plant.

Draw a longitudinal section of a post-pollinated pistil showing entry of Pollen, tube into a mature embryo-sac. Label filiform apparatus, chalazal end, Hilium, antipodals, male gametes and secondary nucleus.
