Webb8 juni 2024 · Phloem sap travels through perforations called sieve tube plates. Neighboring companion cells carry out metabolic functions for the sieve-tube elements and provide them with energy. Lateral sieve areas connect the sieve-tube elements to the companion cells. Once in the phloem, the photosynthates are translocated to the closest sink.
