The statement above is TRUE. The atmospheric cooling that occur where and when aerosol pollution is the greatest is called aerosol effect. Aerosol effect is an example of negative feed back mechanism. A mechanism is described as negative if it reduces variation in either direction. Examples of aerosol are salt crystals and pollen from windblown seawater and soot and sulfates from coal burning. Aerosols can have strong effects on both heating and cooling of the atmosphere. For instance, accumulation of soot in the atmosphere can cause heating. Some aerosols block out the heat of the sun thus causing cooling.

The phloem sap of vascular plants that moves through the
phloem; transports nutrients through fungi by hyphae, as a result of turgor
pressure. Hyphae are elongated tube-shaped structures that are like garden
hoses. They also have inflexible cell walls that may be strengthened by punctured
cross-walls which are called septa.
