Carpels are located at the center of the flower. A carpel may form a simple pistil (the female reproductive organs of the flower), but a pistil may be composed of two or more fused carpels. The carpel is a modified leaf-like structure, enclosing one or more ovules. To learn how many carpels are in a pistil, count the number of divisions in the stigma; if the stigma is not divided, there is only one carpel.
The female part of the flower. A carpel consists of three parts: 1) the ovary, a swollen basal portion containing the ovule, which becomes the seed after fertilisation, 2) styles, extensions of the ovary and 3) stigmas, specialised filaments on which the pollen falls and germinates.
an organ (generally believed to be a modified foliar unit) at the centre of a flower, bearing one or more ovules and having its margins fused together or with other carpels to enclose the ovule(s) in an ovary, and consisting also of a stigma and usually a style.
