Detailed explanation-1: -Cytokinins are present in all plant tissues. They are abundant in the root tip, shoot apex, and immature seeds. Their endogenous concentration is in the low nanomolar range.
Detailed explanation-2: -Cytokinins are more abundant in developing tissues and organs, such as root tip, shoot apex, cambium, and immature organs, and initially it was thought that cytokinins are synthesized in these limited tissues and organs.
Detailed explanation-3: -Final answer: Cytokinins are produced in root tips and germinating seeds in large amounts.
Detailed explanation-4: -Cytokinin is synthesized largely in root tissue and then travels upward to the shoots; some production also occurs in developing leaves. Nutrients will move and accumulate in plant tissue where higher levels of cytokinin are expressed.
Detailed explanation-5: -Cytokinins are present in greater concentration in young fruits and seeds.
