lol none of them,you are confusing yourself,this process takes place because all parts of the plant needs glucose for respiration,so just to transport it it needs to be converted by sucrose for the sake of translocation

Its not a process saying that the parts of plant need glucose. I was asking about the process causing their transportation. Anyways I found out that active transport is involved, not diffusion as energy is required to move sugars (sucrose).

I m talking about p2 5054/22/n/12 Q9a)ii)

 

[usama321]

no the pressure one

ok i thought you were talking about chemistry :O

For the physics one, the answer is simple. When he asks about the TOTAL pressure, you include the pressure of the 15 m of water as well as the atmospheric pressure which is 1.0 × 10^5 Pa
