GOD! hw dumb can i be! just HOW dumb? i guess its todays maths paper tht has left me in this state... usama321 u cldv secretly told me! -.- its embarrassing. like krwa lo in se bas! lol jk...well its question 2
Its not B as Active transport is always against the concentration gradient!
And its not C as... ions are moving within the plasma, so active transport needs to be through a membrane, but more importantly, active transport needs energy, n there is no source in the plasma
And its not D as its a fact that water is pulled up by a "Transpiration pull" in a transpiration stream , which a suction force simply due to transpiration...
But over all, its a FACT that movement of glucose n amino acids in villi takes place due to active transport(in the end).... n u also gotta know that ion uptake y roots is also active transport(in end), as it also comes in xams!!
