Would a defoliated plant respond to photoperiodic cycle? Why? | NCERT solution | Class 11 Biology | Unit-15 Plant Growth and Development



Q.10:- Would a defoliated plant respond to photoperiodic cycle? Why?

 

Answer:-



No, a defoliated plant would not respond to photoperiodic cycle because photoperiodic stimulus is picked up by the leaves only. Even one leaf or a part of it is sufficient for this purpose. For perception of photoperiodic cycle, there must be the presence of leaves under inductive photoperiod, so that, the hormone responsible for flowering can be produced.
