AP BIOLOGY

Detailed explanation-1: -Sepal : The outer parts of the flower (often green and leaf-like) that enclose a developing bud. Petal: The parts of a flower that are often conspicuously colored. Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther.

Detailed explanation-2: -The petals, usually colorful leaf-like structures, attract animals and insects. Sometimes the petals are fused together and form a structure called a corolla. Beneath the petals are green leaf-like structures called sepals.

Detailed explanation-3: -Petals. The colorful, thin structures that surround the sexual parts of the flower. Not only attract pollinators, but also protect the pistil and stamen. May also produce a scent.

Detailed explanation-4: -Petal often consists of two parts: the upper, broad part, similar to leaf blade, also called the blade and the lower part, narrow, similar to leaf petiole, called the claw, separated from each other at the limb. Claws are developed in petals of some flowers of the family Brassicaceae, such as Erysimum cheiri.

Detailed explanation-5: -The sepals, the outermost layer, are usually green, enclose the flower bud, and collectively are called the calyx. Petals are the next layer of floral appendages internal to the calyx; they are generally brightly coloured and collectively are called the corolla.
