Webb28 mars 2024 · Xylem is unidirectional; its job is to make sure water flows upward. However, phloem is bidirectional and transports food and nutrients to all of the plant. Mature xylem is made up of dead cells that do not have cell contents, while phloem contains living cells (albeit without nuclei). The structure of xylem and phloem is also … WebbQuantification of Leaf Phloem Anatomical Features with Microscopy.

WebbPhloem is a living vascular conducting tissue found in angiosperms and gymnosperms. It is composed of three types of cells, sieve elements, parenchyma cells and the supportive cells. Read this article to find a well-labelled diagram of the phloem tissue with all its components explained. Webb26 aug. 2024 · Sap within the phloem simply travels by diffusion between cells and works its way from leaves down to the roots with help from gravity. The phloem is made from cells called ‘sieve-tube members’ and ‘companion cells’. Sieve-tube members. Sieve-tube members are living cells that create chains of cells running the length of the plant.

WebbPlants create sugar in the mesophyll cells of their leaves by photosynthesis. This sugar, mostly sucrose, has to be loaded via the bundle sheath into the phloem vascular system (the sieve elements), where it is distributed to growing parts of the plant.
