Flower Structure and Function

The video tutorial explores the anatomy of flowers, focusing on petals, sepals, and the receptacle. Petals, often brightly colored, attract insects for pollination, while some flowers with dull petals rely on wind pollination. Sepals, or modified leaves, protect the developing flower. The receptacle is the part of the stem where flower organs grow. The tutorial also defines corolla and calyx as groups of petals and sepals, respectively.
