The model is developed by introducing various standard elements in bond graph lexicon. Out of all the resistive elements of plants, stem xylem resistance and stomatal resistance are modeled by taking diurnal variation. The value of stem xylem resistance of the plant is the maximum value at midday ([Formula: see text]MPa s\/m<jats:sup>3<\/jats:sup>) and the minimum value ([Formula: see text]MPa s\/m<jats:sup>3<\/jats:sup>) in the dark period. A Jarvis\u2013Stewart type model for stomatal conductance is implemented for developing stomatal resistance. The process of transpiration which is formulated with the help of Ohm\u2019s law analogy is also incorporated in the model. Thermal behavior of the vegetation is introduced by taking the boundary layer, aerodynamics, ambient temperature, relative humidity and global solar radiation into account. Simulations are performed for specific kinds of plants and for specific sights. Finally, various environmental and physical influencing factors are considered to study the response of the plant model, and this modeling technique offers a novel modeling tactic alternative to field measurements. The transpirational flow at constant water potential of \u22120.15 MPa varies between [Formula: see text] to [Formula: see text]m<jats:sup>3<\/jats:sup>\/s during the day period. The rate of transpiration reaches a maximum value of about [Formula: see text] m<jats:sup>3<\/jats:sup>\/s during the early hours in each day while the value of solar radiation is about 700 Wm<jats:sup>\u22122<\/jats:sup>. Leaf water potential depletes to a minimum value of \u22121.5 MPa at the 5<jats:sup>th<\/jats:sup> day of the drying cycle period.
