The carpel is the female organ of a flower.It consists of the following three parts:
1.Stigma-it is the top part of the carpel which receives the pollen grain during pollination.it is sticky in nature so that the pollen grains can cling onto it.
2.Style-the style is a long tube which joins the stigma with the ovary.the pollen tube grows and reaches the ovary through the style.
3.Ovary-the ovary is the reproductive organ of the carpel which produces the female gamete ovule.it is in the ovary that fertilisation takes place.
