On the contrary, phloem id the vascular tissue which is involved in the transportation of food from the leaves to other parts of the plant.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
