The Leaf
The xylem and phloem are the transport tubes in a plant's root. The xylem carries water and nutrients from the soil up to the rest of the plant, while the phloem transports sugars and other organic compounds produced during photosynthesis throughout the plant.
The letter that typically indicates the region where substances are transported throughout the plant is "V," representing the vascular tissue. This tissue comprises xylem and phloem, which respectively transport water and nutrients from the roots to the rest of the plant and distribute sugars produced by photosynthesis.
A low pressure region should mean that the region is low in air. The air from the surrounding region (which is comparatively at higher pressure) moves into this low pressure region creating a wind. So, wind is the movement of air from a high pressure region into a low pressure region. Warm air is lighter than cold air. Warm air being lighter moves upward creating a low pressure region. So, wind could also be a movement of air from cooler to warmer region.
At 60 degrees latitude, the region is typically a high-pressure region due to the sinking air associated with the subtropical high-pressure belts. This creates stable, dry atmospheric conditions with generally clear skies.
I'm unable to draw images. However, the internal parts of a typical plant stem include the epidermis (outermost layer), cortex (region between the epidermis and vascular tissues), vascular bundles (xylem and phloem for transport), pith (central region for storage), and cambium (tissue responsible for secondary growth).
The pressure flow theory describes the movement of food through the phloem. The theory was originated by Ernst Munch.

Currently, trucks are used to transport goods in and out of the cordillera region of Canada.
Active transport is used to move a molecule from a region of low concentration to a region of high concentration. This process requires energy input in the form of ATP to pump the molecule against its concentration gradient.

When air pressure is constant throughout a region of the atmosphere the region is in a state is called equilibrium.
A low pressure region should mean that the region is low in air. The air from the surrounding region (which is comparatively at higher pressure) moves into this low pressure region creating a wind.
