Water Transport in Plants Introduction In this lab experiment‚ we set out to examine the different transpiration rates of a plant system in certain environments. Water is transported in a plant by the process of transpiration‚ which is the loss of water through evaporation from the surface of leaves. The stomata in leaves are responsible for the diffusion of water vapor. Transpiration brings water upward through the xylem in the plant. There are certain factors that can affect transpiration

What is the Effect of the Colour of Light on the Rate of Photosynthesis? By Amelia Rowan‚ 12SDa Aim To discover whether the colour of the light source has any effect on the rate of photosynthesis of a sample of algae. Hypothesis It was predicted that the colour of the light source would have a very slight effect on the rate of photosynthesis. It was further predicted that when the sample was placed under the green light‚ the rate of photosynthesis would be the lowest. This hypothesis was arrived
