Carpel is a part of a flower which is a female reproductive part. Carpel is generally made up of ovary, stigma, and styles. Carpel is sometimes attached to a basal ovary which is shared and sometimes has an individual ovary itself. Naturally, the ovary is the extended basal portion of the carpel, which contains the placentas.
The pistil is a part of a flower; this part is a female reproductive part present in a flower. The pistil is generally made up of several carpels. Generally, by the floral formula, the flowers which consist of a single pistil and a single carpel are represented as G (1).
Carpel and Pistil of a flower
Carpel and pistil both are the female reproductive part of a flower. A carpel consists or is made up of parts like ovary, stigma, and style, whereas pistil consists of several carpels or it can consist of a single carpel. Naturally, the ovary is the extended basal portion of the carpel, which contains the placentas. The placentas are the backbone of tissues that bear one or more ovules. The style is the pillar-like structure through which pollen tubes reach or grow to the ovary, style has a responsibility to hold the stigma out of the flower to attract and capture pollen grains. The remnant of the megasporangium, the outer layer, the female gametophyte formed from a haploid megaspore, the integument, the nucellus is the parts of the ovule. Monocarpellary pistils are pistils with a single carpel, but polycarpellary pistils are pistils with many carpels. Generally, by the floral formula, the flowers which consist of a single pistil and a single carpel is represented as G (1). Whereas, by the floral formula, the flowers which consist of three distinct and free carpels with separate ovaries, These three distinct and free carpels can be considered as three pistils is represented as G (3). If a flower has three carpels where ovaries are fused with it, this type pistil is known as the compound pistil and the floral formula is represented as G (3). Production of egg cells, production of seeds, undergoing fertilization and helping in the dispersal of seeds are the main function of carpel but pistil does not produce seed. Carpel is a megasporophyll, which is a modified leaf-bearing ovule.
Difference between Carpel and Pistil
Conclusion
Carpel and pistil both are the female reproductive part of a flower. Naturally, the ovary is the extended basal portion of the carpel, which contains the placentas. Production of egg cells, production of seeds, undergoing fertilization, and helping in the dispersal of seeds is the main function of carpel but pistil does not produce seed.
