Name: Aradhana Mahtani Subject: Biology HL Topic: Transpiration Teacher: Ms. Deane Date: 28/09/2007 BIOLOGY PLANNING LAB Research Question: To investigate how the change in wind velocity influences the rate of transpiration. Hypothesis: Transpiration is the loss of water in the form of water vapor from the leaves and stems of plants. Wind speed, among other factors such as light intensity, humidity and temperature is one of the abiotic factors that affects the rate at which transpiration takes place

Unformatted text preview: from the surface of the leaf and the stem. Pockets of air saturated with water vapor tend to form near the stomata in an environment with still air, which reduces the rate of transpiration as the capacity of the air to absorb more water from the surface of the plant is reduced. At high wind velocities, the wind blows the saturated air away and thus the air pocket above the leaf is replaced allowing transpiration...
