AIMS The aim of this experiment was to investigate the effect of temperature rise on the rate of transpiration of a plant (hibiscus) by measuring the plant’s water uptake in a period of time. HYPOTHESIS Transpiration is the process by which plants loses water to the atmosphere from their leaves. Water in the plant is lost to the atmosphere by evaporation. Evaporation of water can occur at any temperature. In the presence of sunlight‚ water in the plants evaporates into the intercellular air

to 28 degrees the slope of the line increases and shows a slight curve. The rate of evaporation increases with temperature since transpiration is a cooling mechanism to release heat. More stomata open as temperature increases as this allows a faster transpiration rate. Although‚ at much higher temperatures‚ plants close stomata to prevent excess water loss. b. The increasing humidity causes reduced transpiration rates. This is because atmosphere is saturated with water vapor and so not much can

Biology Assignment Transpiration rates between Exotic vs. Native plants In this investigation we will be looking at transpiration. The topic we will be focusing on is transpiration rates between native plants as well as exotic plants. We will be experimenting with 2 native plants as well as 2 exotic plants. The reason we are experimenting on this topic is because of Australia’s dry weather‚ we are wanting to find out which plants will be able to hold more water during Australia’s peaking tempretures

Alexander Templet Transpiration Rate in Tomato Solanum lycopersicum Biology 156 Summer 2008 Mr. Leith Adams‚ Instructor Lab Partners: Michael Adams Andrew Scalist Experiments Conducted: 23 June 2008 Abstract Plants draw water up through their roots and out through their leaves. This process is known as transpiration. The transpiration rate is a major determining factor in how quickly plants absorb water‚ and is thus critically important to understand for agriculture.

Marilyn Combalicer Exercise 3 TRANSPIRATION I. Result and Discussion 1. Effect of the Environment Factors on the Rate of Transpiration The quantitative rate of transpiration of the branch of papua dilaw was determined using the potometer. The distance travelled by the bubble in the capillary per unit of time was observed under different treatments: a. in front of a fan‚ b. exposed to light‚ c. fan and light‚ d. no treatment. Table 1. The transpiration rate of the branch of papua dilaw when

In other words‚ transpiration is one of the most important mechanisms in plants which affect and support the flow
Premium Wind Evaporation Transpiration
Transpiration is the evaporation of water from the aerial parts of plants‚ especially leaves but also stems‚ flowers and roots. Leaf surfaces are dotted with openings called stomates that are bordered by guard cells. Collectively‚ the structures are called stomata.[1] Leaf transpiration occurs through stomata‚ and can be as a necessary "cost" associated with many processes such as the opening of the pistil and allowing the diffusion of carbon dioxide gas from the air for photosynthesis. Transpiration

environmental conditions affected the rate of transpiration of a plant. The environmental factors we looked at were the affects of various temperatures and different light amounts in the different temperatures. We found that as the temperature warmed up‚ the rate of transpiration was higher. When the temperature was at five degrees Celsius‚ the rate of transpiration was very low. When we took out half of the light source and measured the rate of transpiration in the three temperatures we found the
