Investigating rate of transpiration essay 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. Up water from their neighbours and xylem vessels withdrawal of water by osmosis from the xylem vessels produces a tension this tension draws water up the vessels of the stem from the roots bringing about the transpiration stream.
