Flower Structure and Terminology

The video tutorial explains the structure and function of petals, sepals, and tepals in flowers. Petals, often colorful, attract pollinators and form the corolla. Sepals, forming the calyx, protect the flower. When petals and sepals are indistinguishable, they are called tepals, as seen in plants like aloe. The video also covers petaloid monocots and the characteristics of wind-pollinated flowers, such as grasses, which may have small or no petals.
