Question

Root hairs absorb water from soil with the help ofa)Root pressureb)Osmatic pressurec)Suction pressured)Turger pressureCorrect answer is option 'B'. Can you explain this answer?

Answer

Root hairs absorb water from the soil with the help of osmotic pressure not suction pressure.opt c is correct

Answer

Root hairs absorb water  not by osmosis  it's by diffusion  in osmosis  water  moves through  a semi permeable  membrane

Answer

Answer

Plants absorb water and minerals salt from the soil with the help of root hairs. They absorb water by the process of osmosis. ... So the water moves into the root hairs through osmosis. Thus the cell of root hairs become turgid and exert pressure on the adjacent cells

Answer

As we know a large number of minerals are absorbed actively from soil to roots. This results in increased concentration of solute in root hair cells and in soil low conc. so according to pressure gradient water moves passively through osmosis by its high concentration (in soil) to low concentration (in root hair cells)

Answer

(A+B)^2= (A+B)(A+B) =A^2+AB+BA+B^2 In matrices AB &BA are not equal and hence we can't write AB + BA = 2AB

Answer

Option b.
osmotic pressure....
there is comparitavely more water in soil as compared to soil...so water moves form soil to roots from its high concentration to low concentration.that is by osmosis

Answer

Because Water Content in the Soil is greater than Water content in root primarily. As a result the O.P in the soil increases .as we know According to gradient the O.P travels from High to Low.Therefore,Water travels from soil to root through Osmosis
