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."

What is one example of how a cell uses active transport?
Sugar. The membrane is impermeable to sugar molecules ... insulin's function is to activate active transport.
Why does a plant's transport of sugar differ from it's transport of water?
Water is transported in Xylem vessels and sugar is transported in the phloem
Does active transport have sugar or amino acid?
I believe so
What is used in facilitated diffusion to assist transport of sugar and sodium molecules?
transport proteins both are carrier proteins and channel proteins
Why does the direction of sugar transport vary from season to season?
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
What sugar does RNA have that is different from the sugar in the morning?
Which mechanism explains the phenomenon

What is the function of a sugar in the body?
Sugar helps to transport the oxygen inside the body.
Why does a plant's transport of sugar differ from it's transport of water?
Water is transported in Xylem vessels and sugar is transported in the phloem
What structure in vascular plants transport sugar?
Phloem transport sugars, Xylem transports water
What are plant pipes that transport sugar molecules?
stem
How does sugar increase blood pressure?
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.
The driving force for the movement of materials in the phloem of plants is?
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
Does passive transport require sugar?
no, that's why its called "passive".
What happens to vapor pressure if sugar is added to a solution?
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.
Which carbohydrate is known as milk sugar and describe the chemistry of milk sugar?
The principal sugar in milk is lactose.
What is the idiom to describe energetic?
the idiom to describe energetic is eating a box of sugar.
