What type of gradient is involved in the pressure flow theory of phloem transport?
The pressure-flow hypothesis explains the function of pholem because ONE DIRECTION IS THE BEST
What else can I help you with?
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.
Contains a nucleus and helps control movement through the sieve cell?
The phloem parenchyma cell contains a nucleus which helps in regulating its metabolic activities. These cells are involved in maintaining the osmotic pressure gradient within the sieve cell, aiding in the movement of sugars and nutrients in the phloem.
Does diffusion help phloem to absorb minerals from the soil or active transport?
Active transport is the primary mechanism through which phloem absorbs minerals from the soil. Diffusion is not as efficient for transporting minerals over long distances within plants. Active transport allows phloem to selectively uptake specific minerals against their concentration gradient to ensure proper nutrient balance in the plant.
Phloem is to food transport as what is to water transport?
xylem
Sugars are conducted through plant tissue by the?
The sieve tubes of the phloem cells help to transport sugars. The stem of the plant has a layer of cells called phloem. Part of the phloem is made of sieve tubes that permit the flow of sugars solution through the influence of fluid pressure differential. The phloem also contains companion cells for the sieve tubes which aid in the transport of sugars to these tubes.

Which vascular tissue is involved in the transport of starch found in fruit pulp?
The phloem tissue is involved in the transport of starch found in fruit pulp. Phloem is responsible for transporting sugars and other nutrients produced by photosynthesis from leaves to various parts of the plant, including fruits. Starch, as a storage form of sugars, is transferred through the phloem to provide energy for growth and development in different plant parts.

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
Phloem is to food transport as what is to water transport?
xylem
In a plant the pressure flow hypothesis explains the movement of sugar from the to the?
The movement of sugars in the phloem begins at the source, where (a) sugars are loaded (actively transported) into a sieve tube. Loading of the phloem sets up a water potential gradient that facilitates the movement of water into the dense phloem sap from the neighboring xylem (b). As hydrostatic pressure in the phloem sieve tube increases, pressure flow begins (c), and the sap moves through the phloem by mass flow. Meanwhile, at the sink (d), incoming sugars are actively transported out of the phloem and removed as complex carbohydrates. The loss of solute produces a high water potential in the phloem, and water passes out (e), returning eventually to the xylem.
How does the structure of xylem and phloem vessels differs microscopically?
differ in such a way that xylem transport water while phloem transport food and nutrients
What are the transport tissues in plant?
Xylem and phloem are the main transport tissues in plants.
Sugars are conducted through plant tissue by the?
The sieve tubes of the phloem cells help to transport sugars. The stem of the plant has a layer of cells called phloem.

The phloem also contains companion cells for the sieve tubes which aid in the transport of sugars to these tubes.
Which tubes in a vascular plant transport food?
Phloem
What cells in a plant transport the food?
xylem & phloem
