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.
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.
Explain the process of translocation of food in plants?
All plants need water. The wilted leaves recover when water is added to the soil, which means that water has been conducted upward into the leaves. You have also learnt that the leaves for photosynthesis need water. Likewise, the food produced in the leaves has to be transported to other parts of the plant including the stem, the roots flowers and fruits etc. All this transportation is the function of conducting tissues.
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
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 substances is transported from leaves to the rest of the plant body?
Sugars (mainly glucose) produced through photosynthesis in the leaves are transported to the rest of the plant body for energy and growth. Additionally, water and minerals absorbed by the roots are also transported to the leaves through the xylem tissue.
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

A tissues transport water and sugar in plant is?
The tissue responsible for transporting water and nutrients in plants is the xylem. Xylem tissue is made up of specialized cells called tracheids and vessel elements, which form continuous tubes for water and mineral transport from the roots to the leaves. Additionally, sugar transport in plants is facilitated by the phloem tissue, which transports sugars produced during photosynthesis to different parts of the plant for growth and energy.
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.

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 are plants made What are plants made up of?
plants are made up of 75-90 percent of flueds
What is one of two monosaccharides made by plants?
Plants make different sugars including sucrose, dextrose and fructose.
