What else can I help you with?
Do phloem cells contain chloroplasts?
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.
What are dead xylem and phloem cells of a woody plant called?
Dead xylem cells are called "tracheids" or "vessel elements," while dead phloem cells are called "sieve cells" or "sieve tube members."
What is the name of the tissue that contains seive tubes?
Parenchyma cells in "phloem tissue"
Function of phloem parenchyma?
Phloem parenchyma cells provide structural support to the phloem tissue and help in the storage of starch, lipids, and proteins. They also facilitate the transport of organic compounds such as sugars and hormones within the plant.
Is mature phloem tissue dead upon maturity?
No, mature phloem tissue is not dead upon maturity. Phloem tissue remains alive and functional, aiding in the transport of sugars and other organic compounds throughout the plant. The cells in mature phloem tissue are specialized for this function and typically stay alive for an extended period.
Are phloem cells alive?
Yes, Phloem cells are alive.
How are mature phloem cells controlled if they lack a nucleus?
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.
What is the difference between the cells that compose xylem and phloem tissue?
the cells of phloem are the only ones with cytoplasm
What are the constituents of phloem?
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.
Do phloem cells contain chloroplasts?
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.
Which structures make up phloem?
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)
What are constituents of phloem?
i) Sieve tubes (ii) Companion cells (iii) Phloem parenchyma (iv) Phloem fibres
Phloem is made up of living cells. Phloem takes sugar in the To the roots?
leaves
Do dead xylem and phloem cells turn into cambium?
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.
What are the xylem and phloem are separated by?
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.
Are the Xylem and phloem grouped together in the cambium?
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.
What is a tissue that moves sugar?
phloem cells
