What are nucleated cells of the phloem which aid in the physiology of sieve tubes called?
The nucleated cells in the phloem that aid in the physiology of sieve tubes are called companion cells. These cells are closely associated with sieve tube cells and provide metabolic support, such as loading and unloading of nutrients, for the sieve tubes.
What is the specialized cell that helps control the movement of sugars through sieve tubes called?
Companion cells are specialized cells that help control the movement of sugars through sieve tubes in plants. They provide metabolic support to sieve tube elements and help maintain the pressure gradient that drives the flow of sugars.
Loaded in if sucrose is actively loaded into sieve tube?
Yes, sucrose is actively loaded into sieve tubes by companion cells that pump sucrose from the photosynthetic cells into the sieve tubes. This process requires energy and allows for long-distance transport of sucrose through the phloem.
What is the structure of the Phloem?
Phloem is composed of sieve elements and companion cells. Each sieve element has a companion cell that provides ATP and other necessary support to the sieve element. In addition to this there are sieve plates that separate sieve cells.
Difference between primary and secondary phloem?
Primary phloem 1. . Derived from procambium of apical meristem. 2. . District protophloem and metaphloem elements.3 Sieve tubes long and narrow. 3. Less or no development of phloem parenchyma. 4. Phloem fibres on the outer part. Secondary phloem 1. . Derived from vascular cambium. 2. . No clear demarcation between protophloems and metaphloems. 3. Sieve tubes short and wide. 4. .Well developed and abundant phloem parenchyma. 5. . Phloem fibers among the phloem parenchyma.
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 companion cells?
Companion cells are typically elongated and have a dense cytoplasm. They are closely associated with sieve elements in the phloem and play a crucial role in supporting the function of these sieve elements by providing them with nutrients and energy.

The nucleated cells in the phloem that aid in the physiology of sieve tubes are called companion cells. These cells are closely associated with sieve tube cells and provide metabolic support, such as loading and unloading of nutrients, for the sieve tubes.
What is the diffference between xylem and phloem?
Xylem contains Vessels, trachieds and xylem parenchyma Phloem consists of sieve tubes, companion cells and phloem parenchyma

Which of this following froms an important component of phloem tissue?
Sieve tubes and companion cells are important components of phloem tissue in plants. Sieve tubes are responsible for transporting sugars and other organic compounds, while companion cells support sieve tube function by providing energy and resources.

What is a sieve phloem?
Sieve phloem is a specialized tissue in plants that is responsible for transporting organic nutrients such as sugars from the leaves to other parts of the plant. It is made up of sieve tube elements and companion cells, which work together to facilitate the flow of nutrients through the plant.
Do plants have a tubes?
Yes angiospermic plants have sieve tubes in their conducting tissues.
