simple pistil
Definition
Noun: A simple pistil is a fundamental reproductive structure in flowering plants (angiosperms). It consists of a single carpel. The carpel is the basic female unit of a flower, typically comprising an ovary (containing ovules), a style (a stalk), and a stigma (a receptive surface for pollen). A flower may contain one or more simple pistils.
Usage
The term is used in botany and plant morphology to describe and classify the female parts of a flower. * In flowers like those of the pea or bean family (Fabaceae), you often find a simple pistil. * The botanist noted that the species was characterized by a single simple pistil per flower. * A simple pistil develops from one folded leaf-like structure (the carpel).
