Phloem cell what does it do
WebbFood and other organic substances (e.g., some plant hormones and even messenger RNAs) manufactured in the cells of the plant are transported in the phloem. Sugars (usually sucrose), amino acids and other organic molecules enter the sieve elements through plasmodesmata connecting them to adjacent companion cells.

The phloem is also a pathway to signaling molecules and has a structural function in the plant body. It is typically composed of three cell types: sieve elements, parenchyma, and sclerenchyma. WebbAlthough its primary function is transport of sugars, phloem may also contain cells that have a mechanical support function. These are sclerenchyma cells which generally fall into two categories: fibres and …

Inside phloem cells are specialized cells called sieves that … WebbWhere does the phloem get food that it carries to the stem and roots? The vascular system is comprised of two main types of tissue: the xylem and the phloem. The xylem distributes water and dissolved minerals upward through the plant, ... The cells that do this work are called the xylem cells.
WebbCollenchyma tissue is composed by elongated living cells of uneven primary thick walls, which possess hemicellulose, cellulose, and pectic materials. It provides support, structure, mechanical strength, and flexibility to the petiole, leaf veins, and stem of young plants, allowing for easy bending without breakage.
WebbXylem and phloem cell fi les have formed by the end of embryo-genesis, but they are not fully differentiated and therefore re-main nonfunctional ( Bonke et al., 2003 ).
