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 else can I help you with?
Does active transport have sugar or amino acid?
Active transport can transport both sugar and amino acids across the cell membrane. This process requires energy in the form of ATP to move these molecules against their concentration gradient.
How do plants transport sugar from the leaves to the rest of the plant?
Plants transport sugar from the leaves to the rest of the plant through a process called translocation. This process occurs in the phloem, where sugar is actively transported from source tissues (like leaves) to sink tissues (such as roots, fruits, and growing tips) through specialized cells called sieve tubes. The movement of sugar is driven by a pressure gradient created by the loading of sugar at the source and unloading at the sink.
What is the process by which molecules of sugar pass through an animal cell membrane to replenish the cell's lack of sugar is?
The process by which molecules of sugar pass through an animal cell membrane is called facilitated diffusion. In this process, sugar molecules move across the cell membrane with the help of specific transport proteins. These transport proteins create channels for the sugar molecules to pass through, allowing them to replenish the cell's supply of sugar.
What is one example of how a cell uses active transport?
One example of active transport in a cell is the sodium-potassium pump, which uses energy in the form of ATP to actively transport sodium ions out of the cell and potassium ions into the cell, against their concentration gradients. This process helps maintain the cell's electrochemical gradient essential for functions such as nerve signaling and muscle contraction.
What is used in facilitated diffusion to assist transport of sugar and sodium molecules?
transport proteins both are carrier proteins and channel proteins
The source region in the pressure flow explanation of phloem transport is most often the?
The source region in the pressure flow explanation of phloem transport is typically the sugar-producing tissues like leaves where sugar is actively loaded into the phloem. This creates a high concentration of sugars in the phloem sap, generating a pressure gradient that drives the flow of sap towards sinks such as growing regions or storage tissues.
What sugar does RNA have that is different from the sugar in the morning?
Which mechanism explains the phenomenon
Is sugar osmosis or passive transport or active transport?
Sugar transport can occur through both passive transport, such as facilitated diffusion or simple diffusion, and active transport, such as primary or secondary active transport processes. Osmosis specifically refers to the movement of water across a semi-permeable membrane, so sugar transport itself is not osmosis.
Does passive transport require sugar?
Passive transport does not require sugar. Passive transport is a process by which molecules move across a cell membrane without the input of energy, such as diffusion or osmosis. Sugar molecules can be transported passively, but the process itself does not depend on sugar.
What is the function of a sugar in the body?
Sugar helps to transport the oxygen inside the body.
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
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.
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.
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.
