In the phloem of angiosperms, a nurse cell that is connected to, and is a sister cell to, an enucleate sieve tube member.
cell-shaped
Companion cells found in phloem tissue have a nucleus. These cells are closely associated with sieve tube elements and play a role in supporting their function by providing energy and nutrients.
Mature phloem cells are regulated by surrounding companion cells, which supply them with necessary proteins and nutrients. These companion cells are connected to the phloem cells by plasmodesmata, allowing for communication and control despite the phloem cells lacking a nucleus.
Phloem vessels are made of living cells, including sieve tube elements and companion cells. Sieve tube elements are elongated cells that form the main transport conduits, while companion cells provide metabolic support to the sieve tube elements. Together, these two types of cells make up the structure of phloem vessels.

Yes. Stems do have cells.

Stem cells
in stems (:
The job of cells found in stems is to uphold the stem and help to keep its shape. Cells also act as a stems "brain" telling it when to capture the correct amount ogf sunlight water and air.
