The upper part of the pistil of a flower that receives the pollen grains and on which they start to grow.
The part of the female structure of a flower that receives the pollen grains.
The pollen receptor on the gynoecium, which may be either sessile on the ovary or on top of the style or style arms.
The damaging labeling of a person or group to indicate that something is abnormal or evil. The stigma of mental illness is still strong enough that many individuals are reluctant or refuse to seek treatment. In some cultures, such as Asian or Hispanic, the stigma of mental illness is much more marked than in non-Western societies, leading to underutilization of mental health services.
The flat, outer end part of the pistil of the flower that receives the pollen grains and on which they germinate.
The (usually sticky) surface at the tip of a style, which receives the pollen and where the pollen grains are stimulated to germinate. A style may have one or several stigmas.
The business part of a carpel, where the pollen lands and is captured.
The portion of the pistil receptive to pollination; usually at the top of the style, and often appearing fuzzy or sticky.
The sticky portion at the top of the pistil of a flower. Pollen will adhere to this part.
A visible symptom which shows that someone has a particular disease.
The upper part of a carpel with specialized receptive cells on its surface, often slightly sticky and hence able to capture pollen grains from visiting insects or birds, or wind-borne pollen. The chemical environment of the stigma allows the pollen grain to germinate, sending a fine tube down through the style of the carpel, this tube containing the pollen parent’s genetic material which then impregnates the ovules, resulting in seeds. Stigmas may be knob-like in form or have various other shapes, including star-shaped.
A mark that characterizes a particular disease, such as the cafe-au-lait spots characteristic of neurofibromatosis.
A mark or spot on the skin; lesions or sores of the hands and feet that resemble crucifixion wounds.
A personal characteristic or trait that leads to societal shame, avoidance, or discrediting of an individual. Mental disorders are frequently associated with stigma, exemplifying this phenomenon.
A tiny mark or spot, often a blood spot found on the palm or sole, occasionally observed in individuals with hysteria; any distinctive mark or sign indicative of a specific disease or condition.
A gap between cells, also known as a stoma.
Delicate structures designed to capture the pollen responsible for fertilizing the ovules.
