WebbPhloem sieve tubes are primarily composed of two main types of cells – sieve element cells and companion cells The phloem also contains schlerenchymal and parenchymal cells which fill additional spaces and provide support Sieve Element Cells Sieve elements are long and narrow cells that are connected together to form the sieve tube WebbThe cell cannot function without certain organelles and must rely on the organelles of the companion cells. The companion cell is responsible for all metabolic functions of the sieve tube member. The companion cell is essential for the survival of the sieve tube member.
