Vedclass · Answer

(C) Abscisic acid $(ABA)$,also known as the stress hormone or dormin,is found in all vascular plants,as well as in some mosses,green algae,and fungi. It is completely absent in bacteria.$ABA$ is primarily synthesized within the chloroplasts of plant cells. The biosynthetic pathway involves the conversion of carotenoids,such as violaxanthin,which are present in the chloroplasts.While leaves are the primary site of synthesis due to the abundance of chloroplasts,$ABA$ can also be synthesized in other plastids like chromoplasts,leucoplasts,or proplastids found in roots,fruits,and seeds.
