2024 Spring Stem Photo Contest
Description
Sunflowers produce seeds through pollination and fertilization. This plant contains both male and female reproductive structures. During pollination grains from the male part of the flower are transferred to the female part, assisted by bees, birds, and butterflies. Fertilization occurs when a pollen grain travels down the style, combines with an ovule in the ovary, and forms a seed. This photo shows the male and female structures in various stages of pollination and fertilization.
