Quizplus · Accepted Answer

Cytokinins are a class of hormones produced in the roots of plants that promote cell division and growth. They also retard the aging of flowers and leaves, helping to prolong the lifespan of the plant. Phytochromes are involved in regulating plant growth and development in response to light, ethylene is involved in the ripening of fruits and the senescence of leaves, and gibberellins are involved in stem elongation and other growth processes.
