Plant sap and tree sap originate in the roots and then climb to nourish the leaves. We take advantage of this ascension in maple trees. When their sap begins to ascend in the Spring, we tap the trees and collect and boil the sap in the production of maple syrup. Vet59Man

∙ 14y agoAns: Ascent of cell sap can be compared to our digestive and circulatory system. The ascent of sap helpls the plant for the transportation of water and other nutrients thruogh the root system and it also helpls to pass the food which is prepared in the leaf of the plant.

∙ 11y ago1) Transpiration pull - When water is lost through the leaf stomata it is called transpiration .
2) Root pressure - Root hair are constantly absorbing water from the soil, building an internal pressure called root pressure . This root pressure constantly pushes water in the xylem elements in the roots .

When stem of a herbaceous plant is cut water or sap oozes out dis is due to?
this is due to the upward movement of water/sap in the plant which is called ascent of sap.
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 is the Scientific term for process of colored water travelling up the stem of a flower?
trans-location via capillary action/ Ascent of sap
When a firework rocket is on its way up how does gravity affect it?
Gravity slows its rate of ascent.
Describe the path taken by water at the moment it enters the leaf and leaves through the stomata?
The water enters the leaf by ascent of sap. It is used in photosythesis. It reappears or synthesized during respiration and ultimately leaves through stomata by transpiration.
Do transpiration have no effect over ascent of sap?
Yes, transpiration have effect over ascent of sap because trnspiration cause suction force which makes the sap rise upward. The process of rising of sapis callled ascent of sap.
Who discovered ascent of sap?
I have no fricken idea!

What takes water and minerals from the root to the shoot?
Xylem tissue by ascent of sap

What two forces drive the flow of water from the roots to the leaves?
transpiration and ascent of sap
What is the process called when roots supply water to the tree?
Osmotic absorption of water by root hairs and ascent of sap.
What is the Scientific term for process of colored water travelling up the stem of a flower?
trans-location via capillary action/ Ascent of sap
What is an ascent rate for scuba diving?
no more than 18 meters per minute
When a firework rocket is on its way up how does gravity affect it?
Gravity slows its rate of ascent.
Does the stoma open or shut in the light?
OpenIn day light , they are open, and perform the following three functions1. Transpiration2. Gaseous exchange3. Promotion of ascent of sap
Bryophytes are not large plantsThey are typically small why?
because they do not have vascular bundles i.e. xylem n phloem.. n vascular bundle is an imp source of ascent sap..
