40 EPG=10 micro metres (0.1mm=10 micrometres)
so radius is (50x10)/40 = 12.5 micrometres
Area of a circle=pi x r x r
=pi x 12.5 x 12.5
= 490 micrometres
=4.9 x 10^2 micrometres
(someone explained before)

Lol go over the questions again. A was that they're extensively folded to allow expansion....C was that they're folded to increase the SA. The answer was A....and in the second question, it said that histamine is released without antibody-antigen binding. See deep down we all know that these answers are damn weirdinfolded to allow expansion for increasing S.A not for gaseous exchange
yes to increase inflammation and make mast cells release histamine to attract nearby neutrophils.
you gave 12?what variant?
bcz companion cells are there to provide energy for the seive tube cells.... ATP is a source of energywhy is ATP needed in companion cells?

yes, anyways we have finished p1... so no need further explanationsLol go over the questions again.

i dont know about that.. but i think that it just is there to keep the seive tube celll alive.. and procide energy like respiration and stuff... do confirm from another sourceI know that
But precisely which step of translocation needs ATP?
1)for pumping H+ ions out of the seive tube (initial step of translocation) or
2)for loading of sucrose
