Relationship between osmotic potential & pressure potential with water potential

Relationship between osmotic potential & pressure potential with water potential Explain the relationship between osmotic potential & pressure potential with water potential. ·        Water potential mainly depends on concentration, pressure, and gravity. If the symbols of water potential, the effects of solutes, pressure, & gravity are denoted by Ψw, Ψs, Ψp & Ψg  , then water...

Plant Hormones: Cytokinins

CHAPTER: 15(D) Plant Hormones: Cytokinins Cytokinins: •      Cytokinins (CK) are a class of plant growth substances (phytohormones) that promote cell division, or cytokinesis, in plant roots and shoots. •      They are involved primarily in cell growth and differentiation, but also affect apical dominance, axillary bud growth, and leaf senescence.  •      There are...
