Jul 4, 2018 · Apart from pigments that selectively absorb light at specific wavelength ranges, three main characteristics determine a flower’s reflectance: the refractive index difference between floral structures, the flower’s interior inhomogeneity and the flower’s thickness.

May 11, 2016 · We first provide an overview of the general optical characteristics of flowers, i.e. the fractions of reflected, transmitted, and absorbed light, flower absorbance spectra and types of pigment localization.

Flowering plants react to light, gravity, infection by pathogens, drought, and, as with the Venus flytrap, touch. Animals have two systems on which they can rely to detect and respond to stimuli: the nervous and endocrine systems. Plants, however, only have chemical control mechanisms at their disposal.
Photomorphogenesis is the growth and development of plants in response to light. It allows plants to optimize their use of light and space. Photoperiodism is the ability to use light to track time. Plants can tell the time of day and time of year by sensing and using various wavelengths of sunlight.
We see a molecule as “colored” when the object absorbs light at a wavelength that matches some wavelength in the visible part of the electromagnetic spectrum. If a molecule absorbs blue light, the object reflects orange light and we see the object as orange.
May 8, 2020 · We now have the ability to study the development of live flowers, from a few dividing cells at the tip of a stem to mature flowers undergoing pollination and fertilization, with access to gene expression and hormone signaling, over a wide range of physical and temporal scales.
