Question

Poppy plants were exposed to the inductive photoperiod with some or all leaves covered with aluminum foil during the induction time. The results are shown in Table B. What do these results indicate about the photoperiodic signal receptor?

Table B

Condition	Percent flowering
All leaves intact	100
All leaves covered	0
All but one leaf covered	100

Answer 1

Answer:- In first situation when all leaves are intact,it means no leaves are covered then all the leaves are able to get suight and done their essential processes like making food or transfer of harmones.This helps in flowering of flowers.

But in 2nd situation,when all leaves are covered with aluminum foil,no leaves get sunlight during photoperiod,hence they are unable to make food for plant therefore inhibit flowering.

in 3rd situation when only one leaf is covered by aluminum foil,then is 100 percent flowering because others leafs are uncovered and they get proper sunlight to make food with compromise the lose of food and harmones done by covered leafs .so,there is 100% flowering.
