The movement of sugars through the phloem is called?
Translocation.
What is phloem sap?
Phloem sap is a nutrient-rich, watery fluid that flows through the phloem tissue of a plant. It is responsible for transporting sugars, amino acids, hormones, and other organic molecules from the leaves, where they are produced through photosynthesis, to other parts of the plant. Phloem sap moves through the plant in a process called translocation.
What are the structures in stems that carry fluids up and down the stems?
The two structures in the stem of a plant are xylem and phloem. Xylem goes up and carries water and nutrients to the the leaves while phloem goes down and carries sugars to the roots of the plant.
Sugars are conducted through plant tissue by the?
The sieve tubes of the phloem cells help to transport sugars. The stem of the plant has a layer of cells called phloem. Part of the phloem is made of sieve tubes that permit the flow of sugars solution through the influence of fluid pressure differential. The phloem also contains companion cells for the sieve tubes which aid in the transport of sugars to these tubes.
Which cells in a plant can translocate dissolved sugars?
Phloem
The movement of sugars through the phloem is called?
Translocation.
Translocation and transpiration?
There is a direct relationship between translocation and transpiration. Translocation refers to movement of sugars which are dissolved in the phloem while transpiration refers to the process through which water is moved from the roots to the stomata through the xylem.
What is phloem sap?

It is responsible for transporting sugars, amino acids, hormones, and other organic molecules from the leaves, where they are produced through photosynthesis, to other parts of the plant. Phloem sap moves through the plant in a process called translocation.
Function of phloem?
Unlike xylem (which is composed primarily of dead cells), the phloem is composed of still-living cells that transport sap. The sap is a water-based solution, but rich in sugars made by the photosynthetic areas. These sugars are transported to non-photosynthetic parts of the plant, such as the roots, or into storage structures, such as tubers or bulbs.

The two structures in the stem of a plant are xylem and phloem. Xylem goes up and carries water and nutrients to the the leaves while phloem goes down and carries sugars to the roots of the plant.
How does translocation occur in a plant?
Translocation in plants refers to the movement of organic substances, mainly sugars produced during photosynthesis, from one part of the plant to another. This process primarily occurs in the phloem, which is a specialized vascular tissue responsible for the transport of these substances. During photosynthesis, sugars (mainly sucrose) are synthesized in the leaves. These sugars need to be transported to other parts of the plant, such as roots, stems, and fruits, for energy and growth. The process of translocation involves the following steps: Sugar Loading : In the source (usually leaves), sugars are actively transported into the phloem cells. 2 Water Movement : The entry of sugars into phloem cells creates a high solute concentration, leading to water movement into these cells by osmosis. Pressure Buildup : The influx of water increases pressure within the phloem, creating a positive pressure called turgor pressure. Mass Flow : The pressure gradient created by the turgor pressure causes the movement of sugars along with water through the phloem toward the sink (the part of the plant where the sugars are needed). Sugar Unloading : At the sink (roots, growing tissues, sugars are actively transported out of the phloem cells and used for various metabolic processes or stored. Translocation is a crucial process for the distribution of nutrients and energy throughout the plant, supporting its growth and development.
Why is phloem useful to a plant?
Phloem is a conductive plant tissue and is found in the stems and leaf veins. It facilitates the movement of the sugars produced by photosynthesis to the rest of the plant. Phloem also provides a minor role in the support structure of the stem.
What is translocated from the leaves to the growing parts of the plants?
Translocation is the transport of sugars throughout the plant. The phloem is responsible for this, and has sieve tube members and companion cells that connect via the plasmodesmata in order to transport the sugars.
What is in the xylem and phloem?
Water and Sugars!!
What does the phloem do in a plant?
transports sugars
