Stephen Hales (1677-1761) was a English priest and scientist who gave accurate accounts of water movement in plants.
His work laid emphasis on measurement and experimentation.
Hales demonstrated that plants absorb air, and that some part of air is involved in their nutrition. He also measured plant growth and water loss, relating this to the upward movement of water from plants to leaves (transpiration).
