Question

what is root pressure ???? explain​

Answer 1

Answer:

⏩Root pressure is the transverse osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves. Root pressure occurs in the xylem of some vascular plants when the soil moisture level is high either at night or when transpiration is low during the day.⏪

Explanation:

Root Pressure: Definition

Look outside your window. All of that plant life, even the tallest trees, have gravity-defying properties that allow nutrients to be 'sucked' up from the deepest depths of the soil and moved to the highest branches! This lesson takes a look at how plants have the amazing ability to transport water and nutrients upwards using a complex array of biological processes.

Plants are complicated organisms, and one of the many intriguing processes of a plant is root pressure. Root pressure is basically the idea that a plant's roots can either maintain a higher or lower pressure based on its surroundings. It does this in order to promote or discourage nutrient uptake. In other words, the root system of a plant can alter its pressure to either: a) help water and/or nutrients rise throughout the plant, or b) push water and/or nutrients out of the plant. Biologists are usually concerned with the former, and how it affects the rise of water and nutrients in a plant.
