Stigma is the receptive tip of a carpel in the female reproductive organ of a plant. Learn about its shape, structure, function and variation in different plant families and species.
The stigma (pl.: stigmas or stigmata) is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Diagram showing the stigma-style-ovary system of the female reproductive organ of a plant. The stigma is fixed to the apex of the style, a narrow upward extension of the ovary.
11 cze 2004 · This article reviews the cellular and molecular aspects of pollen and stigma biology, and how they vary across angiosperm taxa. It also discusses the evolutionary significance of pollen and stigma diversity and the challenges of studying it.
Learn the definition and features of stigma, the receptive tip of the carpel that receives pollen in flowering plants. Find out how stigma is adapted, secreted, and involved in pollination and fertilization.
Stigma is the part of a flower's pistil that receives pollen during fertilization. It plays a crucial role in the reproductive process by capturing pollen grains, which are essential for the fertilization of ovules.
