Vedclass · Answer

(B) Transpiration is the process of water loss from the aerial parts of plants,primarily through stomata. Factors affecting transpiration include light,temperature,humidity,wind speed,and soil water availability. $A$. Companion cells are involved in phloem loading and unloading,not directly in the transpiration process. $B$. Constant temperature implies no change in temperature,meaning it does not act as a variable factor influencing the rate of transpiration. $C$. Xylem elements are the conduits for water transport,but the rate of transpiration is determined by external environmental factors and stomatal regulation,not by the xylem elements themselves. $D$. Soil moisture directly affects the water potential of the plant and the availability of water for transpiration. Among the given options,'Constant temperature' represents a state of no change,making it ineffective as a variable factor influencing the rate of transpiration.
