Sugar is transported through a plant by the "veins" in the plant called phloem. Xylem is the other transportation system that transports water.

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.
Why is it important that a plants phloem extends into its leaves?
Any cell that is using sugars for respiration act as a "sink" for sugars being transported by the phloem. As the sugar is consumed, more will move to the area of less concentration as long as the leaf cells keep on producing sugars. It is called the pressure-flow hypothesis. This process insures all cells needing the energy found in the sugar molecules will get enough energy to continue growth of the plant.
What is the function of phloem?
Unlike xylem (which is composed primarily of dead cells), the phloem is composed of still-living cells that transport sap and forms part of the plants vascular system. The sap is a water-based solution, but rich in sugars made by the photosynthetic areas (mainly in the leaves). These sugars are transported to non-photosynthetic parts of the plant, such as the roots, or into storage structures. Transport in the phloem is generally in a downward direction within the plant. food transport
Phloem is made up of living cells. Phloem takes sugars in the to the roots?
leaves
Which way does the phloem transport food?
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 - predominantly a downward movement from the leaves.
Where are the sugars traveling in the phloem produced?
Sugars made in photosynthesis in the chloroplasts of leaves are transported throughout the plant (up & down) as sucrose.The leaves represent the source and the tissues receiving the sucrose are called the sinks eg. buds, growing points etc. S
What substances is transported from leaves to the rest of the plant body?
plants have two "tubes" running up and down the plant. One is called the xylem, which transports inorganic substances from the roots upwards, towards the leaves. The other is called the phloem, which transports organic substances manufactured in the leaves to all parts of the plant.

What moves sugars that are made in the plant's leaves?
phloem in vascular tissue.
What moves sugars that are made in plant leaves?
phloem in vascular tissue.
Why would the plant die if the phloem and xylem is removed?
It would die as water and minerals absorbed from the roots cannot be transported to other parts of the plant.Food made by the leaves cannot be transported to other parts of the plants too.So,the leaves and stems do not get the water and minerals absorbed by the roots.The roots and stems also cannot get the food made by the leaves.Hence,the plant will die eventually.
Food for plants are made here?
the food for plants are made in the cloroplats in the leaves.
What is one of two monosaccharides made by plants?
Plants make different sugars including sucrose, dextrose and fructose.
What are plants made What are plants made up of?
plants are made up of 75-90 percent of flueds

Why are leaves greens?
Leaves are green because the cells form which they are made contain structures called chloroplasts which are filled with a green coloured chemical called chlorophyll. Chlorophyll absorbs all the light which is not green and uses the energy in this light to make sugars. Thus the green leaves of plants make the food that plants need to grow (and which animals get when they eat plants).
