One of the main functions of phloem is the transportation of sap and organic molecules such as sugars, amino acids, certain hormones, and even messenger RNAs within the plant. The phloem function in the process of translocation. It also serves as a site for oviposition and breeding of insects. Websectional area A of phloem conduits is approximately equal in angiosperms and gymnosperms (A stem ∼ 500–1000 μm2; see Ref. [8]). In contrast, phloem conduits in conifer leaves are remarkably small, with areas in the range A ∼ 3–10 μm2 [9]. While the factors that limit phloem cell size to this range

WebPhloem mostly contains sugar molecules dissolved in water forming a very thick sugary sap, which is food for them. And if you're wondering what these things are over here at the sides, that is some leftover cytoplasm. The cells don't lose all of their cytoplasm. And similarly, this is the cell walls. They have developed gaps in between. WebSucrose transported in phloem by mass flow. Glucose converted to cellulose. Describe the processes involved in the transport of sugars in plant stems. At source, sucrose is actively transported into the sieve tubes by companion cells. This lowers water potential in phloem so water enters by osmosis.This produces high hydrostatic pressure.
