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 theory explains how water is moved from roots to leaves?
The cohesion-tension theory explains how water is moved from roots to leaves in plants. This theory suggests that water is pulled up through the plant by the cohesive forces between water molecules and the tension generated by transpiration in the leaves. This creates a continuous water column that is pulled up through the xylem.
What happens to flow when pressure is increased?
Pressure decreases.
The flow of water flowing into the xylem is regulated by?
The flow of water flowing into the xylem is regulated by the process of transpiration and the cohesion-tension theory. Transpiration creates a negative pressure that pulls water up through the xylem, while cohesion between water molecules helps maintain a continuous column of water within the xylem.
How do pressure gradients affect bulk flow?
Pressure gradients drive bulk flow by creating a difference in pressure between two points, causing the movement of fluids from high pressure to low pressure areas. The greater the pressure gradient, the faster the bulk flow of fluids will occur.

What is pressure flow?
The pressure flow theory describes the movement of food through the phloem. The theory was originated by Ernst Munch.
What is the Effect of oil on separation process?

What is flow and non flow process of themodynamic's?
flow process : it is one in which fluid enters the system and leaves it after work interaction,which means that such processes occur in the systems having open boundary permitting mass interaction across the system boundary. non flow process : it is the one in which there is no mass interaction across the system boundaries during the occurrence of process. different type of non flow process of perfect gas are given below: (1) constant volume process (2) constant pressure process (3) Isothermal process (4) adiabatic process (5) polytropic process
How does bernoulli's principle explain Bunsen burner work?
Bernoulli's principle explains how the flow of a fluid (gas in this case) changes with pressure. In a Bunsen burner, gas is released at high pressure through a small opening, creating a fast flow of gas. As the gas flows from the high-pressure area to the low-pressure area around the burner, it mixes with air and ignites, producing a flame.
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.
What happens to flow when pressure is increased?
Pressure decreases.
What is the formula for converting flow to pressure in a hydraulic system?
The formula for converting flow to pressure in a hydraulic system is: Pressure Flow x Resistance.
The flow of water flowing into the xylem is regulated by?
The flow of water flowing into the xylem is regulated by the process of transpiration and the cohesion-tension theory. Transpiration creates a negative pressure that pulls water up through the xylem, while cohesion between water molecules helps maintain a continuous column of water within the xylem.
What is the relationship between pressure and flow rate in a system, as described by the pressure vs flow rate equation?
In a system, the relationship between pressure and flow rate is described by the pressure vs flow rate equation. This equation shows that as pressure increases, flow rate decreases, and vice versa. This means that there is an inverse relationship between pressure and flow rate in a system.
