Phloem cell what does it do
WebbIt has been known for several years that small globular proteins such as free green fluorescent protein (GFP) not only readily enter sieve elements from the companion cells (most likely through intercellular channels called plasmodesmata), but also that they are transported across large distances through the phloem and can be unloaded from the … WebbPhloem transports new materials (the sugars created from photosynthesis) from the crown to the roots. Dead phloem tissue becomes the bark of a tree. The band of tissue just inside of the cambium is the xylem, which transports water from the roots to the crown. Dead xylem tissue forms the heartwood, or the wood we use for many different purposes.
