Why do flower petals sparkle?
Iridescence in plants occurs due to tiny grooves on the surface of flower petals. These ridges diffract light and change the way the petals look depending on the angle at which they are viewed. In other words, the color of the petals appears to change as you look at them from different angles.
What makes flower petals sparkle?
VISUAL EFFECTS OF CONICAL CELLS (1981) hypothesized that conical petal cells would focus light into petals, enhancing colour. They further suggested that the cone shape might have a light-scattering effect, generating a sparkling appearance.
Which tissue is present in petals of flower?
The petal is generally a thin structure, with a mesophyll-type cell layer between an ordered upper and lower epidermis. Petal cell walls are constructed in such a way as to be able to accommodate large and quite fast increases in cellular turgor during petal expansion and flower opening.

What are the two types of Mesophyll?
In dicotyledonous leaves there are two types of mesophyll cells, palisade mesophyll and spongy mesophyll. Palisade mesophyll cells form a layer beneath the upper epidermis whereas spongy mesophyll cells are internal to the lower epidermis.
