Sieve elements are a key component of phloem, the conductive tissue through which plants transport carbohydrates and a wide range of signalling molecules. Elongated cylindrical cells are capped at one end by a sieve plate and arranged end-to-end to form sieve tubes which in turn form a network throughout a plant's body.
