Phloem transports sugar in the vascular tissue system. In the ground tissue system, it is stored and includes mesophyll, where most photosynthesis occurs. Understanding this, I believe , sugar-flow mechanism or transpirational-pull mechanism; this would explain the mechanism of sugar transport. This is because "a vascular tissue called phloem, sends sugars from leaves or storage tissues to all parts of the plant."

Sugar. The membrane is impermeable to sugar molecules ... insulin's function is to activate active transport.
Water is transported in Xylem vessels and sugar is transported in the phloem
I believe so
transport proteins both are carrier proteins and channel proteins
In summer the plant makes alot of sugar, so it is transported to the roots for storage. In the winter, there is less light and less photosynthesis occurs, so sugar is trasnported to the leavesto use it as energy
Which mechanism explains the phenomenon
Sugar. The membrane is impermeable to sugar molecules ... insulin's function is to activate active transport.
Sugar helps to transport the oxygen inside the body.
Water is transported in Xylem vessels and sugar is transported in the phloem
Phloem transport sugars, Xylem transports water

Sugar does not directly increase blood pressure (as in the higher the surgar the higher the blood pressure. Chronically elevated sugar (diabetes) doe predispose to vascular disease which can lead to high blood pressure. I don't think we completely understand why it does that.
Phloem ~ Pressure Flow Theory The phloem tissue moves products of photosynthesis by active transport. The flow of materials in phloem is an active process that requires energy. The mechanism of flow is driven by an osmotic pressure gradient, generated by difference in sugar and water concentrations. Just remember photosynthesis= water + sugar water= osmosis sugar=gradient
no, that's why its called "passive".
When you add a teaspoon of honey to water with vapor pressure, it will reduce the vapor pressure. The sugar in the honey leads to the pressure going down.
The principal sugar in milk is lactose.
the idiom to describe energetic is eating a box of sugar.
