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.
When stem of a herbaceous plant is cut water or sap oozes out dis is due to?
When the stem of a herbaceous plant is cut and water or sap oozes out, it is due to the pressure within the plant's vascular system. The xylem and phloem tissues, which transport water and nutrients throughout the plant, are under pressure, and cutting the stem releases this pressure, causing the water or sap to flow out.
Rising air warmed by the release of latent heat cools at the rate of?
10 K/km (in the troposphere)
Can tree sap be melted?
Yes, tree sap can be melted by applying heat. When heated, the sap softens and becomes more fluid. This can be useful for various applications such as making resin-based products or removing sap from surfaces.
What causes the tree sap to be purple?
Purple tree sap can be caused by a chemical reaction between the sap and certain minerals or compounds present in the tree. This reaction can create pigments that give the sap a purple color.
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
Do transpiration have no effect over ascent of sap?
Transpiration creates a negative pressure that helps pull water upward in the xylem vessels, playing a major role in the ascent of sap in plants. As water evaporates from the leaf surface during transpiration, it creates tension that helps to draw water molecules up from the roots. This process, known as the cohesion-tension theory, is essential for the movement of water and nutrients throughout the plant.
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 an ascent rate for scuba diving?
no more than 18 meters per minute
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..

If 120 gallons of sap are needed to make 3 gallons of maple syrup find the unit rate?
40 gallons of sap per gallon of syrup
