A structural adaptation of a rose is that many different types have thorns on their stems. They also are very strong flowers.

have sharp leafblades that cut the skin.
Grana are defined as the stacks of thylakoids embedded in the stroma of a chloroplast. The adaptive value of the breakdown of chlorophyll is that the important minerals it contains can be re-cycled.
It is a structure in eukariyotes. So they have eukariyotic cells

thorns
A structural adaptation of plants is that bark helps limit the moisture evaporated from atree trunk.
Homology in the pentadactyl limb, where different species share a common limb structure despite having different functions, is evidence for adaptive radiation because it suggests that a common ancestor with this limb structure diversified into various species to adapt to different environments or ecological niches. The conservation of the pentadactyl limb's basic structure implies that these species diverged from a shared ancestor through adaptive changes to exploit different habitats and resources.
The protective structure of a rose is the thorns. The thorns grow up and down the stems of the plant. It protects the plant from being eaten.
