Hey buddy,

Here's your answer ⤵️⤵️⤵️

✈COMPANION CELLS:

☆DEFINITION:

Companion cells found in the phloem cells of a plant are companion cells.

☆FUNCTIONS:

• Companion cells in the veins of leaves function in the transfer of assimilates from photosynthetic tissues and bundle sheaths into the sieve tubes.

• Apoplastic loading, a process utilizing energy, is facilitated by carrier proteins called sucrose transporters which are located in the plasma membranes of companion cells and/or sieve tube members.

• Companion cells that function as transfer cells are characterized by extensive wall in growths that vastly increase the surface area of the plasma membrane.

• Companion cells also play an important role in maintaining the viability and long-distance translocation system of the enucleate sieve tube members by providing them with proteins, including informational (signaling) molecules, and ribonuclear protein complexes as well as ATP.

Hope it helps ☺️
