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.

What are sieve tubes and sieve tubes cells and sieve plates?

Seive tube elements:It includes sieve tubes and sieve cells. Both of these are thin -walled living cells . Sieve tube members are long slender tube-like joined end to end to form long tubular to form a long tubular channel. Seive plates are present at the end of the tube . Adjacent sieve plates . Main function of this tube is translocation of organic solute.


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 is the structure of the Phloem?

Phloem is composed of sieve elements and companion cells. Each sieve element has a companion cell that provides ATP and other necessary support to the sieve element. In addition to this there are sieve plates that separate sieve cells.


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 difference between companion cell and sieve tubes?

Companion cells have the structure of a 'normal' plant cell. Sieve tubes don't have nuclei, tonoplasts and ribosomes. Also there are no sieve plates in a companion cell, whereas there are in sieve tubes.

What is the function of the sieve plate?

Sieve plates are pores in the plant cell walls that facilitate transport of materials between two sieve tubes. from: http://en.wikipedia.org/wiki/Sieve_tube_element


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.
