I had learnt in a plant biology course that, all the flowers are actually originating from leaves, with several mutations. I wonder what makes a flower sparkly like this.
Photos belong to a Phalaenopsis Orchid (White) (under direct sunlight) . But I believe this can be observed in many plants.
When searched for it, I saw one explanation on that they shine right after they are watered. But I observed this long after the plant was watered. So I guess this is not the case.
Also I've read about the pigments that absorbs different wavelenghts and give the plant its color. But I couldn't find an explanation about this sparkling view.
Another thing I read was about the shiny views of some flowers, like buttercup flower. It is said that this is originating from flat cell shapes. (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5332578/). But again, this is different than what I am asking.
Biology is not my major (probably as you have already guessed :)), so I might not be searching it with the right keywords. So I will be glad to get some help. Thank you :)!
Edit:
Another photo, taken with flash light. The shiny view is only in the side leaves (petals and sepals), not in the middle parts.
