Table 2: The effects of transpiration rate with changing factors Independent Variables Heat Increased humidity Decreased air movement Darkness Increased air movement Decreased surface area Control (ml/hr) 1.46ml/hr 1.46ml/hr 1.46ml/hr 1.46ml/hr 1.46ml/hr 1.46ml/hr Experimental (ml/hr) 1.84 0.65 0.80 0.90 1.95 .85 State the effect of the experimental condition on the rate of transpiration The increased heat will increase transpiration because it will cause more water to be pulled out of the plant This will cause transpiration
