_________are living cells that do not conduct sugar themselves.

Companion cells are important structures found in the vascular bundle known as the phloem of plants. They work together with sieve cells in the movement of vital compounds such as Protein, ATP etc to other parts of the plant.

Companion cells are also known as living cells that do not conduct sugar themselves but they play a very important role in the movement of these substances.

Companion cells are living cells that supply ATP, protein and other nutrients to the sieve elements but do not conduct sugar themselves.

Companion cells are parenchymal cells found within the phloem that direct the flow of nutrients through the sieve tubes, which do not have the cellular maintenance structures.

The elements of the sieve depend on the companion cells to do much of the metabolic work required to transport sugars and other nutrients.

Therefore, we can conclude that companion cells are highly specialized parenchymal cells that support the sieve elements in the transfer of sugars in the plant.
