A sieve demonstrates selective permeability by allowing certain-sized particles to pass through while blocking larger particles. This is similar to how cell membranes selectively allow certain molecules to enter or exit the cell based on their size and charge.
it allows some but not all materials to cross

When was Nectar in a Sieve created?
"Nectar in a Sieve" was written by Kamala Markandaya and first published in 1954.
What is a sieve phloem?
Sieve phloem is a specialized tissue in plants that is responsible for transporting organic nutrients such as sugars from the leaves to other parts of the plant. It is made up of sieve tube elements and companion cells, which work together to facilitate the flow of nutrients through the plant.
Where is the sieve tube located?
The sieve tubes are located in the phloem tissue of plants. They are responsible for transporting sugars and other nutrients throughout the plant.
How is a sieve tube adapted to its job?
A sieve tube is adapted to its job of transporting sugars by having specialized sieve plates that allow for the movement of sugars and other materials between adjacent cells. These sieve plates have pores that facilitate the flow of sap. Additionally, sieve tubes lack many organelles, allowing for more efficient transport of materials.
What is the structure of the Phloem?
Phloem is composed of sieve tubes, companion cells, fibers, and parenchyma cells. Sieve tubes are long cells that transport organic compounds, companion cells support the sieve tubes, fibers provide structural support, and parenchyma cells store nutrients. Together, these components make up the vascular tissue responsible for transporting sugars and other organic nutrients throughout the plant.
How does a sieve colander demonstrate the property of selective permeability?

How does a sieve or colander demonstrate the property of selective permeability?
A sieve or colander demonstrates selective permeability by allowing smaller particles, like water or liquid, to pass through while blocking larger particles, like solids. This property is based on the size of the holes or pores in the sieve or colander, which determine what can pass through and what gets caught.
What is the permeability of No. 8 gravel No. 67 limstone No. 8 limestone No. 57 stone and limestone sand?
The permeability of different types of gravel and limestone can vary depending on their particle size and porosity. In general, larger stone sizes like No. 8 gravel and No. 57 stone have higher permeability compared to smaller sizes like limestone sand. Lime stones may have moderate permeability depending on their gradation and compaction. It is recommended to conduct specific permeability tests in the laboratory to determine the exact values for each material.
Who made the sieve?

What is sentence of sieve?
You can sift flour using a sieve.
What does sieve meen?
A sieve is a very fine screen used to filter, or sieve, solids out of liquids.
What is the difference between a wet sieve and a dry sieve analysis?
A wet sieve analysis involves using water to wash finer particles through the sieve, while a dry sieve analysis does not involve any added moisture and relies on natural particle movement through the sieve openings. Wet sieve analysis is typically used for cohesive materials, while dry sieve analysis is more commonly used for non-cohesive materials.
What the conclusion the sieve analysis?
the importance of sieve analysis
