Which cell found in phloem tissue has a nucleus?
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.
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 are phloem vessels made of?
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.
What geometric shape may be similar to the onion cells shape?
Onion cells are rectangular in shape.
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.
What is the shape of the chief cells of frogs red blood cells?
The shape of the chief cells of the frogs red blood cells is that they are biconcave in shape.
Which cell found in phloem tissue has a nucleus?
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.
What is the shape of the chief cells of human red blood cells?
The shape of the human red blood cells is that it is biconcave in shape.

What is the shape of the chief cells of skeletal muscles?
The shape of the chief cells of the skeletal muscles is that they are tube-shaped.
What geometric shape may be similar to the onion cells shape?
Onion cells are rectangular in shape.
What cells are wine glass shape?
cells the shape of wine glasses are called columnar cells.
How do plants cells retain their shape compare to how animals cells retain to there shape?
Plants cells retain their shape using a cell wall whereas animals cells retain shape with their cell membranes.
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.
Why should cells in different shape and sizes?
All cells ARE NOT the same shape. Cells can be of diverse structures.
What is the definition of companion cells in stems?
Companion cells are specialized parenchyma cells found in the phloem of plant stems. They are closely associated with sieve tube elements and help support their function by providing nutrients and maintaining cellular processes. Companion cells play a crucial role in the transport of organic compounds through the phloem.
