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.
