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. WebbXylem and phloem cell ﬁ les have formed by the end of embryo-genesis, but they are not fully differentiated and therefore re-main nonfunctional ( Bonke et al., 2003 ).

Webb16 juli 2024 · The phloem is associated with the movement of sugars throughout the plant. The cells of the phloem involved in this transport are sieve cells. Why do xylem cells have to be empty? Also, they need to be hollow to allow water to pass up them; organelles get in the way especially vacuoles. So they have to be empty thus dead for that.

WebbPhloem tissue transports photosynthetic products, other organic molecules (e.g., plant hormones and waste products), and soluble nutrients throughout the plant. Unlike xylem, phloem is alive at maturity, but usually with a much reduced cell contents and no nucleus. 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 …
