When the seasons change and snow begins to fall, which type of leaf (maple or pine) is more stable? Why?

The pine leaf is more stable because it is an evergreen tree, the leaves of these trees don not die in winter therefore they are more stable. The chlorophyll of the maple leaf is absorbed back into the trunk of the tree to help it survive, making the leaves brown or orange and thus dying.

No that answer is wrong. you have written the function of mitochondria in chloroplast and function of chloroplast in mitochondria.
