What carries the sap from the roots up the trunk?
The xylem tissue in a plant carries sap from the roots to the leaves through a process called transpiration. Water and nutrients are absorbed by the roots and then pulled up through the xylem vessels by evaporation of water from the leaves.
What would we be able to study by injecting a nutrient dye into a root of a plant?
Xylem sap transport
What meant by the ascent of xylem water?
Ascent of xylem water is also known as the ascent of sap as sap contains minerals dissolved in water. Ascent of sap is actually the movement of sap from the roots all the way to the leaves where it can be utilized in photosynthesis. There are two prposed theories so as to exlain the ascent of sap. One is the "Root Pressure Theory" which says that root exerts a pressure on the water to push it upwards by absorbing more from the soil. But this pressure works only for a few metres. The second theory is more acceptable; "The transpiration Pull". According to this one, when water is transpired through the leaves, the evaporating water molecules pull the ones after them with the help of the adhesive and cohesive forces. This helps in the ascent of water from the roots, all the way through the xylem, to the leaves.
What kind of plant sap do cicada eat?
Cicada actually suck the sap of plants not eat it. They are partial to a number of plants and not one soecific host. Plant sap is plant sap, basically insects feed off of it because it is high in Nitrogen - normall at the growing points of the plant where the concentrations of nitrogen are at their highest
Is tree sap a liquid?
Yes, tree sap is a liquid. It is a sticky and viscous substance that flows through the xylem of a tree, carrying nutrients and water from the roots to the leaves.
Sap rises through what plant material?
Sap rises through the xylem of the plant. The xylem is one of the two transportation materials in a plant.
How water is absorbed and moved into the leaf via the xylem?
Two phenomena cause xylem sap to flow:Transpirational pull: the most important cause of xylem sap flow is the evaporation of water from the surfaces of mesophyll cells to the atmosphere. This transpiration causes millions of minute menisci to form in the mesophyll cell wall. The resulting surface tension causes a negative pressure or tension in the xylem that pulls the water from the roots and soil.Root pressure: If the water potential of the root cells is more negative than the soil, usually due to high concentrations of solute, water can move by osmosis into the root from the soil. This causes a positive pressure that forces sap up the xylem towards the leaves. In some circumstances, the sap will be forced from the leaf through a hydathode in a phenomenon known as guttation. Root pressure is highest in the morning before the stomata open and allow transpiration to begin. Different plant species can have different root pressures even in a similar environment
What takes water and minerals from the root to the shoot?
Xylem tissue by ascent of sap
The type of vascular tissue that carries sap upward is?
Xylem is the vascular tissue that carries sap upward in plants. It consists of parenchyma cells, fibers, vessels, and tracheids that transport water and minerals from the roots to the rest of the plant.
What substance would you expect to find in phloem but not in xylem?
Sugars, amino acids, and hormones are substances typically found in phloem sap but not in xylem sap. These substances are transported in the phloem to various parts of the plant for growth and energy production.

Why is there sap on the leaves of the linden tree?
What causes the sap on a Linden tree? and what can I do?

Plant sap is plant sap, basically insects feed off of it because it is high in Nitrogen - normall at the growing points of the plant where the concentrations of nitrogen are at their highest
How does sap coming out of the tree?
Sap comes out of a tree through internal pressure that builds up and forces the sap to flow through special tubes called xylem. When the tree is injured or tapped (for example, during maple syrup collection), the sap is released through these openings in the bark.
Why can colored water be seen flowing up through a celery stalk?
According to research and data, water transports into a celery stick by moving through it's veins and going up to the leaves. Imporoved answer: the celery absorbs the water through the xylem tubes, this tubes carry the water all the way up to the leaves.
