The fruit of a sunflower is an elongated tetrahedral or laterally compressed seed consisting of a pericarp (peel, or husk) and a white seed (kernel) covered with a seed coat. In the pericarp of modern sunflower varieties between the sclerenchyma and cork tissue there is a shell layer, due to which the achenes are not damaged by sunflower fire.
