What is the hypothesis that explains the movement of fluid through phloem in a plant?
The hypothesis that explains the movement of fluid through phloem in plants is known as the "pressure flow hypothesis." It posits that the movement of sap, which contains sugars and nutrients, occurs due to differences in turgor pressure between source tissues (where sugars are produced or stored) and sink tissues (where they are utilized). As sugars are actively loaded into the phloem at the source, water enters osmotically, creating high pressure that drives the flow of the sap toward areas of lower pressure at the sinks.
What else can I help you with?
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
The movement of sugars through the phloem is called?
The movement of sugars through the phloem is called translocation. This process involves the transport of sugars, primarily sucrose, from sources (areas of photosynthesis or sugar storage) to sinks (areas of active growth or storage). Translocation is facilitated by specialized cells called sieve-tube elements in the phloem.
Water moves into phloem by?
Water moves into phloem primarily through the process of osmosis, where it travels from areas of high water concentration to low water concentration. This movement helps create the pressure that drives the flow of nutrients and other substances through the phloem tissue.
Why does water follow the sugar as it moves through the phloem?
What's The phloem
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.

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.
Water moves into phloem cells by osmosis and creates an increased pressure that pushes the sugr and water in the phloem to the rest of the plant. this is description of moving materials through the p?
This process is known as translocation, which involves the movement of sugars and water through the phloem in plants. The pressure flow hypothesis explains how this movement occurs due to the osmotic pressure created by the accumulation of sugars in the phloem. As water enters the phloem cells by osmosis, it creates pressure that helps push the sugar and water solution to various parts of the plant where it is needed for growth and metabolism.
Which of the following statements about the distribution of sap throughout a plant is true?
The true statement is: "Sap is primarily transported through phloem tissue in plants." This is because phloem is responsible for the distribution of organic nutrients and sugars produced through photosynthesis to different parts of the plant.
Plant that depends on diffusion to move materials?
I assume you are referring to the mass flow hypothesis, where water from the Xylem is diffused into the phloem, adding pressure inside of the phloem which causes the movement of materials through the plant. Any good A-level (erm...or American equivalent?) textbook will have a full description of mass flow hypothesis. I found (a long time ago :( ) when I was learning this that drawing yourself a diagram of it helps a lot. Good luck.

Which process requires more energy from the plant moving water up through the xylem or moving nutrients down through the phloem?
Moving water up through the xylem requires more energy from the plant compared to moving nutrients down through the phloem. This is because water movement in the xylem involves overcoming gravity and transpiration, which requires energy to pull water from the roots to the leaves. Nutrient movement in the phloem, on the other hand, occurs through pressure flow and does not require as much energy expenditure from the plant.
