Why do Autumn leaves fall?

Why do leaves fall off in the autumn??

  • A- The tree is preparing for the development of new branches. B- The water in the leaves freezes, making the leaves too heavy to remain on the tree. C- The tree is better able to conserve its resources D- The leaves are damaged and must be replaced.

  • Answer:

    The best of these terrible answers is "C". The real reason is that an enzyme stops being produced in the leaf that allows photosynthesis thus killing the leaf and it falls off.

Principally it's 'C', but there is also an argument that deciduous trees lose their leaves in winter to prevent strong winds from blowing them down. It would be an evolutionary selection as trees that retained their leaves would be killed. Evergreens don't lose anywhere near as much moisture through their small leaves and are also better adapted to cooler or wamer, but more consistent climates.
