In what vascular tissue is sugar mainly transported?
Sugar is mainly transported in the phloem, which is one of the two types of vascular tissues in plants. The phloem is responsible for the translocation of organic nutrients, particularly sucrose, from sources such as leaves (where photosynthesis occurs) to sinks like roots, fruits, and growing tissues. This transport process is essential for plant growth and energy distribution.
Where does sugar get transported to by phloem in plants?
In plants, sugar, primarily in the form of sucrose, is transported through the phloem to various parts, including growing tissues such as roots, stems, and developing fruits and leaves. This transport is essential for providing energy and carbon skeletons for growth and metabolism. The movement occurs from source tissues, like mature leaves where photosynthesis occurs, to sink tissues, which are areas of growth or storage. This process is driven by pressure differences created by active loading and unloading of sugars in the phloem.
What happens to the sugar produced in the leaves of a plant?
The sugar produced in the leaves of a plant is transported down to the roots, stems, and other parts of the plant through specialized tubes called phloem. This sugar is used as a source of energy for growth, maintenance, and reproduction in different parts of the plant.
Which part of the plant absorbs minerals for photosynthesis?
The roots of a plant absorb minerals from the soil, such as nitrogen, phosphorus, and potassium, which are essential for photosynthesis to occur in the leaves. Minerals are transported from the roots to the leaves through the vascular system of the plant.
Why does a plant's transport of sugar differ from its transport of water?
Because sugar is transported through phloem and water is transported through xylem.
What does the direction of sugar transport vary from season to season?
The direction of sugar transport in plants varies from season to season primarily due to changes in photosynthesis and energy demands. During the growing season, sugars are produced in the leaves and transported to growing tissues (like roots and fruits) for growth and development. In contrast, during the dormancy of winter, stored sugars are transported from roots and stems back to the leaves to maintain metabolic functions. This seasonal shift helps plants optimize energy use and support growth cycles.
In what vascular tissue is sugar mainly transported?
Sugar is mainly transported in the phloem, which is one of the two types of vascular tissues in plants. The phloem is responsible for the translocation of organic nutrients, particularly sucrose, from sources such as leaves (where photosynthesis occurs) to sinks like roots, fruits, and growing tissues. This transport process is essential for plant growth and energy distribution.
Carry water to the leaves and carry sugar and oxygen from the leaves to the living parts of the plant that need it?
Xylem carries water from the roots to toward the leaves. Phloem carries sugar and nutrients from the leaves toward the roots. Oxygen is transported by diffusion, NOT by the liquid transport system.
How do plants transport sugar from the leaves to the rest of the plant?
Plants transport sugar from the leaves to the rest of the plant through a process called translocation. This process occurs in the phloem, where sugar is actively transported from source tissues (like leaves) to sink tissues (such as roots, fruits, and growing tips) through specialized cells called sieve tubes. The movement of sugar is driven by a pressure gradient created by the loading of sugar at the source and unloading at the sink.

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 happens to the sugar produced in the leaves of a plant?
The sugar produced in the leaves of a plant is transported down to the roots, stems, and other parts of the plant through specialized tubes called phloem. This sugar is used as a source of energy for growth, maintenance, and reproduction in different parts of the plant.
What is the south Atlantic system?
Sugar, transported from sugar plantations in Brazil and the west indies
How is the sugar produced by photosynthesis transported from the leaf?
The sugar produced by photosynthesis in the leaf is transported through a network of tubes called phloem. These tubes carry the sugar to other parts of the plant where it is needed for energy or storage.
The root is an example of a photosynthetic sink tissue in plants True or False?
True. The sugars made during photosynthesis in the leaves (sugar source) are transported by the means of the pressure-flow hypothesis to sugar sinks. The roots are a sink since there is a low concentration of sugar and they need more from sugar sources to grow.
Which part of the plant absorbs minerals for photosynthesis?
The roots of a plant absorb minerals from the soil, such as nitrogen, phosphorus, and potassium, which are essential for photosynthesis to occur in the leaves. Minerals are transported from the roots to the leaves through the vascular system of the plant.

Because sugar is transported through phloem and water is transported through xylem.
