Sieve plates are cross walls separating the cells in the phloem and have lots of minute pores. These cross-walls look like a sieve and so are called sieve plates.

The holes in the sieve plates allows rapid flow of manufactured food substances through the sieve tubes.

How is the sieve plate evidence against the pressure flow model?

The presence of sieve plates in phloem tubes allows for bidirectional flow, which contradicts the unidirectional flow proposed by the pressure flow model. The sieve plates also enable some sieve elements to be blocked while others remain functional, challenging the notion of a continuous flow in the phloem.


What is sieve shaker used for?

A sieve shaker is used to apply mechanical vibrations to a stack of sieves to help separate particles based on size. This process is commonly used in soil analysis, aggregate testing, and other particle size distribution studies in various industries like pharmaceuticals, food processing, and construction.


What happens when you put sand in the sieve?

When you put sand in a sieve, the smaller particles of sand will pass through the sieve mesh while the larger particles will be trapped on top of the sieve. This allows for the separation of the sand based on particle size.


What happens if a sponge is placed through a sieve?

If a sponge is placed through a sieve, the sponge will likely get stuck in the sieve's mesh due to its size and inability to compress easily like a liquid or fine particles. It may require manipulation or cutting to remove the sponge from the sieve.


If you pour rock salt over a sieve will it go through?

No, rock salt, being larger in size than the holes in the sieve, will not go through the sieve. The sieve will only allow smaller particles or substances to pass through, while retaining larger ones.

How are pits perforation plates and sieve plates similar in function but different in structure?

Pits are small openings in the wall. Perforation plates are larger openings. A sieve plate looks similar to a sieve that is used in the kitchen. They all allow things to move across cell walls.


What do you mean by sieve no10?

"Sieve no.10" usually refers to a specific mesh size in a sieve analysis used to determine the particle size distribution of a sample. In this case, "no.10" typically corresponds to a sieve opening of 2.00 mm. The sieve analysis helps in characterizing the size of particles in a material sample.


How is a sieve tube adapted to its job?

The end walls of the sieve tubes are perforated and these perforated end walls are called sieve plates. Pores in the sieve plates offer less resistance to flow of liquid.Little cytoplasm in cells = only forms a thin layer lining the inside of the wall of the cell.cells of the sieve tube are living,thus facilitating translocation.sieve plates allow the phloem to seal itself rapidly if it is cut,since it can clot due to callose as a carbohydratesieve plates act as supporting elements thus preventing the phloem from collapsing. .

What is the process of sieving?

Sieving is the process of separating particles based on their size using a sieve or mesh. The material to be sieved is poured onto the sieve, and then the sieve is agitated or tapped gently to allow smaller particles to pass through while larger particles are retained on top. This method is commonly used in industries such as food processing, agriculture, and pharmaceuticals for particle size analysis and separation.


What is the difference between a filter and a sieve?

filter paper is paper and a sieve is a kitchen utensil used to put objects (pasta,rice) and drain water.filter paper is used to seperate smaller granules (sand etc.) and a sieve is used to seperate larger granules(peas, rice, pasta etc.)


The cells that function with the sieve tubes are the?

Cells containing sieve plates are called sieve tube members, a component of the phloem, which carries sugars produced in the leaves to various parts of the plant. They are characteristic of angiosperms (flowering plants) while gymnosperms (cone-bearing plants) have only sieve cells. Sieve cells and sieve tube members are collectively referred to as sieve elements.


Do discussion about sieve analysis?

Sieve analysis is a method that is typically used in civil engineering to determine the size of particles and how those particles are distributed. A discussion about sieve analysis could be conducted after using a series of sieves to filter out different particles of sand.

What is used to measure flour particle size. What is the screened dish called?

Chances are it is called a sieve. It used to be the most common size characterization method and by many is still considered the gold standard, however recent advances in size characterization have replaced it, due to ease and speed. The way it works is that the sieve has holes a preset size and particles that are smaller can pass through, while particles that are bigger remain in the sieve. By stacking sieves of different hole (mesh) sizes one can determine the mass weighted particle size distribution.


What is sieve analysis?

Sieve analysis is carried out to estimate particle size distribution in a given feed material. Sieve types normally designated by Tylor mesh series.
