The results from this Investigation showed Increased transpiration In the plants with the greater number of leaves compared to the ones with less leaves. To determine the validly of this claim, the same plants with different numbers of leaves were tested with same amounts of water, same temperature, and same apparatus and other carefully controlled variables. Introduction 1 Plants draw water in through their roots, and then transport it through the xylem up to the branches and leaves. Water exits the leaves through the stomata in the form of water vapor.

Polarity causes the water exiting through the stomata to draw after it the water in the xylem, which then pulls in more water through the roots. This process is known as transpiration (Raven, 2002). This report will talk about biological theories and values on transpiration as well as transpiration rates and how the results of this Investigation can be applied and shown In real world applications. Finding a successful method to grow plants and food can be very difficult; there are so many variables to cope with such as water, the pH of water, the temperature, wind, unlighted, temperature and other crucial variables.

Plants that are grown in the ground have many more variables and factors to deal with compared to plants in science labs. For example plants that are grown in soil have to deal with Author pressure (turgidity) which is the main pressure of the cells contents against the cell wall in plant cells; this force gives the plant structural balance and physical growth as it expands the plant cells. Transpiration is a vitally important process in plants, and to study it further the experimenters designed and conducted an experiment to assure the rate of transpiration in the same plants with different numbers of leaves.
