Vedclass · Answer

(B) Companion cells are specialized parenchyma cells closely associated with sieve tube elements in the phloem. Their primary function is to maintain the pressure gradient in the sieve tubes. They assist in the active loading of sucrose into the sieve tube elements from the source (leaves) by providing the necessary energy $(ATP)$. This creates a high osmotic pressure in the sieve tubes,which facilitates the translocation of food.
