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.
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 is the hypothesis that explains the movement of fluid through phloem in a plant?
The hypothesis that explains the movement of fluid through phloem in plants is known as the "pressure flow hypothesis." It posits that the movement of sap, which contains sugars and nutrients, occurs due to differences in turgor pressure between source tissues (where sugars are produced or stored) and sink tissues (where they are utilized). As sugars are actively loaded into the phloem at the source, water enters osmotically, creating high pressure that drives the flow of the sap toward areas of lower pressure at the sinks.
Sugars are conducted through plant tissues by the what?
Phloem
What are tissue in plants that moves sugars downward from the leaves?
The tissue in plants that moves sugars downward from the leaves is called phloem. Phloem is part of the vascular system and is responsible for the transport of organic nutrients, particularly sucrose, produced during photosynthesis. This movement occurs through a process known as translocation, where sugars are actively transported to various parts of the plant, including roots and growing tissues.
What moves the sugars produced by plants?
Sugars produced by plants are move through a process called translocation. This process involves the sugars being transported through phloem vessels, which are specialized tubes that transport nutrients within the plant. Energy for this movement is provided by the plant through various mechanisms such as active transport and pressure gradients.

The phloem also contains companion cells for the sieve tubes which aid in the transport of sugars to these tubes.
Which of the following statements about the distribution of sap throughout a plant is true?
The true statement is: "Sap is primarily transported through phloem tissue in plants." This is because phloem is responsible for the distribution of organic nutrients and sugars produced through photosynthesis to different parts of the plant.

Which cells in a plant can translocate dissolved sugars?
The phloem cells are responsible for translocating dissolved sugars in plants through a process called translocation. These specialized cells form tubes that transport the sugars, mainly sucrose, from the leaves where they are produced through photosynthesis to other parts of the plant for energy or storage.
How are the sugars made in leaves transported in plants?
Sugars produced in leaves during photosynthesis are transported through the plant in the phloem tissue. The sugars move in a process called translocation, which uses pressure gradients to move the sugars from the source (leaves) to the sink (such as roots, fruits, and other growing parts of the plant). This process is powered by energy from the plant and relies on specialized cells called sieve tubes in the phloem.
What is old phloem called?
Old phloem is called the secondary phloem. It is produced by the vascular cambium in plants and serves to transport sugars and other nutrients throughout the plant.
In a plant the pressure flow hypothesis explains the movement of sugar from the to the?
The movement of sugars in the phloem begins at the source, where (a) sugars are loaded (actively transported) into a sieve tube. Loading of the phloem sets up a water potential gradient that facilitates the movement of water into the dense phloem sap from the neighboring xylem (b). As hydrostatic pressure in the phloem sieve tube increases, pressure flow begins (c), and the sap moves through the phloem by mass flow. Meanwhile, at the sink (d), incoming sugars are actively transported out of the phloem and removed as complex carbohydrates. The loss of solute produces a high water potential in the phloem, and water passes out (e), returning eventually to the xylem.
What is called the food conducting tissue of a plant?
The food conducting tissue of a plant is called phloem. Phloem is responsible for transporting sugars and other organic nutrients produced by photosynthesis throughout the plant.
