Hint:The movement of water and dissolved minerals assumes a focal part in the development of water among cells and different compartments inside plants. Without happening, osmotic powers rule the development of water into roots. Root pressure results when solutes gather to a more prominent fixation in root xylem than other root tissues.
Complete answer:Due to the absence of a heart or circulatory framework in plants, the progression of water upward through the xylem in plants can accomplish genuinely high rates up to 15 meters for every hour.
The transpiration pull is the theory that helps in the movement of water and minerals. At the point when the pressure creates because of happening, it is called transpirational pull. In this way, the right answer is 'cohesion-tension theory.' So, option A is correct.
Photosynthesis produces glucose in the green pieces of plants, which are regularly left. This is then changed over into sucrose. The sucrose is moved around the plant in phloem vessels. The development of sucrose and different substances like amino acids around a plant is called translocation. So, option B is incorrect
Tensile strength is an estimation of the power needed to pull something, for example, rope, wire. So, option C is incorrect.
It recommends that water containing food particles streams under tension through the phloem. The weight is made by the distinction in water grouping of the arrangement in the phloem and the moderately unadulterated water in the close by xylem channels. This is called the pressure-flow hypothesis. So, option D is incorrect.
Hence, option A is correct.
Note: The development of water and broken down minerals from the roots to the leaves is best clarified by the Cohesion-pressure hypothesis. This hypothesis was advanced by Dixon and Joly in 1894. This hypothesis tells that there is a constant section of water from the root through the stem and into the leaves. The upward development of water is principal because of the production of negative power or pressure ascribed to the constant dissipation of water at the surfaces of leaves.
