Chilling its petiole slows the rate at which food is translocated out of the leaf (above). Oxygen lack also depresses it. Killing the phloem cells puts an end to it. The Pressure-Flow Hypothesis

Webb5 sep. 2024 · Phloem is the vascular tissue in charge of transport and distribution of the organic nutrients. 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. WebbIt has been discovered that the angiosperm phloem can use the sieve tubes as a way to transport various forms of RNA to sink tissues which can help alter transcriptional activity. Sink tissues are tissues that are in the process of growth and need nutrients.

WebbAnd thus, the water present in the xylem column transports up to the tip of the stem, leaves, etc. The direction for water and mineral in xylem is always unidirectional (up). Food 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.
