Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.

Some leaves have a petiole, which attaches the leaf to the stem; leaves that do not have petioles are directly attached to the plant stem and are called sessile leaves. The arrangement of leaves on a stem is known as phyllotaxy; leaves can be classified as either alternate, spiral, opposite, or whorled.

A complete flower is a plant biology term that is used to describe a flower that is built with four parts which include the sepals, petals, pistils and stamens. If any of these four parts, which are integral in forming a flower, is missing, a flower is called an incomplete flower.
