For 10 points answer this question about flowers?
The pistil is the collective term for the carpel(s). Each carpel includes an ovary (where the ovules are produced; ovules are the female reproductive cells, the eggs), a style (a tube on top of the ovary), and a stigma (which receives the pollen during fertilization).

Reply:A typical flower has the following parts and their individual component.





1) Calyx = The outer most floral whorl , usually green in color.


the individual components are Sepals ( All sepals together form Calyx)





2 ) Corolla = It is inner to calyx . Usually attractively colored.The individual components are called Petals ( All petals together form corolla.)





3 ) Androecium = It is the third floral whorl in the sequence . It is commonly refereed to as the Male Reproductive Whorl and its individual components are called Stamens . The anther at the top produce Pollen Grains.( All stamens together form Androecium )





4 ) Gynoecium OR Pistil = It is the last and the inner most floral whorl . The individual members are called Carpels . The ovary at the base contains ovules that turn in to seeds after pollination and fertilization. ( All carpels together form Gynoecium or Pistil )





So , Pistil == All the carpels taken together == Gynoecium.





Pistil may be monocarpellary ( Only one carpel )





Or it may be polycarpellary ( Many carpels)








This is just basic information limited to the question asked.





A diagram is on the link below , just click it --
