What else can I help you with?
Are phloem cells alive?
Yes, Phloem cells are alive.
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.
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
What would happen to a plant without functional phloem cells?
The plant would wilt and die as it would not be able to receive water from the roots. For this reason cut flowers are placed in water to extend their life. If a vascular plant is subjected to cut its phloem in the stem region (leaving its xylem tissue intact), this plant will die of starvation because transportation of water and menerals is done by xylem and phloem transports the prepared food material to different plant parts. In a situation where phloem is dis-connected to the roots, the food supply to the roots will be stopped. Thus roots in the absence of nourishment will not be able to absorb water and minerals and the plant will die ultimately.
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.
