Question

Choose the correct answer from the alternatives given.
Yellowing and shedding of leaves in autumn in many trees is an example of:

• A. overall senescence
• B. top senescence
• C. deciduous senescence
• D. progressive senescence

Answer 1

The correct option is C deciduous senescence

In temperate deciduous trees such as elm and maple, all the leaves senesce and fall at certain seasons of the year like late autumn in October. This is also called as simultaneous senescence. It is controlled by environmental factors.

So, the correct option is 'deciduous senescence'.
