Florigen is synthesized in ____and transported to the _______.
Leaves, Intercalary meristem
Shoot apical meristem, Leaves
Intercalary meristem, Stomata
Leaves, Shoot apical meristem
Plants respond to the systemic signal known as florigen to start flowering (Chailakhyan, 1936). It is synthesized in the leaves and transported to the shoot apical meristem (SAM), where it stimulates the transition to flowers. Hence, option 4 is the correct answer.
