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.
The phloem consists mainly of sieve tubes, companion cells, phloem fibers, and parenchyma cells. Sieve tubes are responsible for transporting sugars and other organic compounds, while companion cells support sieve tube function. Phloem fibers provide structural support, and parenchyma cells store nutrients.
The xylem and phloem are separated by vascular cambium in woody plants. This layer of meristematic tissue is responsible for producing new xylem and phloem cells, allowing the plant to grow in diameter.
No, dead xylem and phloem cells do not turn into cambium. The cambium is a layer of actively dividing cells in the vascular system of plants that gives rise to new xylem and phloem cells. Dead xylem and phloem cells are typically used for structural support or transport of water and nutrients, and they do not have the ability to transform into cambium cells.
No, the xylem and phloem are not grouped together in the cambium. The cambium is a layer of cells in between the xylem and phloem that is responsible for secondary growth in plants. It gives rise to new xylem and phloem cells as the plant grows.
Yes, Phloem cells are alive.

the cells of phloem are the only ones with cytoplasm
No, phloem cells do not contain chloroplasts. Chloroplasts are typically found in plant cells that are involved in photosynthesis, such as leaf cells, while phloem cells are specialized for transporting nutrients, such as sugars, throughout the plant.
The phloem consists mainly of sieve tubes, companion cells, phloem fibers, and parenchyma cells. Sieve tubes are responsible for transporting sugars and other organic compounds, while companion cells support sieve tube function. Phloem fibers provide structural support, and parenchyma cells store nutrients.
Phloem tissue consists of: conducting cells, generally called sieve elements; parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells; and supportive cells, such as fibres and sclereids.(attribution: wikipedia, Phloem)
