Phloem definition biology plants
WebbWater potential and transpiration influence how water is transported through the xylem in plants. These processes are regulated by stomatal opening and closing. Photosynthates (mainly sucrose) move from sources to sinks through the plant’s phloem. Sucrose is actively loaded into the sieve-tube elements of the phloem. Webbphloem. [ flō ′ĕm′ ] A tissue in vascular plants that conducts food from the leaves and other photosynthetic tissues to other plant parts. Phloem consists of several different kinds of …

WebbThey may be components of the xylem and/or phloem or may occur independently of vascular tissue. Sclereids may also function in structural support, but their role in some plant organs is unclear; they may possibly help to deter herbivory in some plants. http://api.3m.com/xylem+and+phloem+vessels
WebbPhloem transports assimilates (substances made by the plant) from the source (i.e. areas where they are produced, like leaves) to a sink (areas where they are used or stored, like the root or the flower).
