why are flowers brightly colored, shape, and smell all work together to attract pollinators. Without these bees (and other insects and small animals) flowers wouldn’t be able to reproduce.

The primary reason why flowers are brightly colored is to attract pollinators. Pollination is when pollen from one flower fertilizes an egg cell in another flower (or other plant). This is necessary for plants to reproduce. Flowers use their sweet scents and brightly colored petals to attract bees, hummingbirds, butterflies, bats, and other animals that help with pollination.

Flowers get their colors from pigments called anthocyanins and carotenoids. These pigments are localized inside structures called plastids in the cells of the plant. Anthocyanins produce red, purple, and blue colors while carotenoids give yellow and orange hues. The color of a flower also depends on the light that it receives and its temperature. Different wavelengths of light and the amount of sunlight that a flower gets can affect its color.

The bright colors of a flower and patterns on its petals reflect ultraviolet energy, or UV. Bees can see UV and will be attracted to a flower that reflects it. When bees visit a flower, they collect nectar from it and spread pollen from the flower to other flowers as they fly away. When a bee visits another flower that has been pollinated, the pollen sticks to the bee’s body and can then transfer to the next flower, fertilizing it. This process is called cross-pollination.
