A grid is sometimes called a sieve because it can be used to strain or separate different components of a mixture, similar to how a sieve is used to separate solids from liquids or smaller particles from larger ones. The grid's structure allows smaller components to pass through while retaining larger ones, mimicking the function of a sieve.
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.
Companion cells are typically elongated and have a dense cytoplasm. They are closely associated with sieve elements in the phloem and play a crucial role in supporting the function of these sieve elements by providing them with nutrients and energy.
No, mitosis does not occur in the phloem. Mitosis is the process of cell division, and in the phloem, specialized cells called sieve elements are responsible for transporting sugars. These sieve elements are formed via a process called differentiation, not mitosis.
The conducting cell in phloem tissue is called a sieve tube element. These elongated cells are responsible for transporting sugars and other organic compounds throughout the plant. Sieve tube elements are connected end-to-end to form sieve tubes, which are an integral part of the plant's vascular system.
The American word for a sieve is "strainer."
Yes
Both a grid and a sieve is composed of vertical and horizontal lines with spaces in between. An example of a grid is a spreadsheet. An example of a sieve is a colander, or a gardener's riddle that is used to remove stones from soil.
One method for finding prime numbers is called the "Sieve of Eratosthenes" because it basically "sifts" through the numbers looking for numbers that are not not prime.
A grid is often referred to as a sieve because both structures serve a similar purpose: they separate or filter out certain elements while allowing others to pass through. In cooking, a sieve is used to strain liquids from solids, while in data processing or analysis, a grid can filter information based on specific criteria. The analogy emphasizes the function of both tools in sorting and categorizing.

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.
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.
the sieve plate is a filter for the water that enters the "Water Vascular System" in Echinoderms.
The word "sieve" in this context is used figuratively with reference to the fact that a sieve does not hold all its contents. Think of sprinkling numbers at the top of the page. The composite numbers get caught, the prime numbers sift on down.

Dead xylem cells are called "tracheids" or "vessel elements," while dead phloem cells are called "sieve cells" or "sieve tube members."
