WebTraditionally, broad spread technologies (splash plate) was used for the distribution of slurries. They cause a maximum of slurry-air contact and therefore a maximum of ammonia emissions. A band spreader means a significant improvement because it applies the liquid fertiliser in narrow bands (reducing the slurry surface on land) and the use of distributing … Web2 days ago · A sieve tube is a prime component of the phloem tissue present in the angiosperms. These cells are accompanied by companion cells forming an elegant transportation system to deliver carbohydrates and other organic compounds to the rest of the plant parts. Sieve tubes and companion cells are dominantly present in this tissue.

WebThe sieve retains larger particles. Sieving is the process of using a sieve to separate materials of various sizes of materials. With the support of a netting or perforated bottom vessel through which the material is agitated or poured, the material is exposed to mechanical forces of vertical and lateral movement. WebPhloem- It consists of four of elements: sieve tubes, companion cells, phloem fibres and the phloem parenchyma. Unlike the xylem, phloem conducts in both directions. It is responsible for transporting food from the leaves to the other parts of the plant. Phloem contains living tissues except for fibres that are dead tissues.
WebFigure 6. Phloem is comprised of cells called sieve-tube elements. Phloem sap travels through perforations called sieve tube plates. Neighboring companion cells carry out metabolic functions for the sieve-tube elements and provide them with energy. Lateral sieve areas connect the sieve-tube elements to the companion cells.
