CIE would not enter into discussion over the answers from Marking Scheme or Examiner report! It's written on the first page.

And for suppose if its the actual answer thn

Sadly that can't be done.

thats not the testa...they come out from the middle and then EXTEND towards the following
Radicle extends towards the lower side while plumule goes up...hope you understand...

i hope this will help you...

Remember the question in atp a guy asked about? there was this seed and he wanted to know which part to draw. In that there were 2 white spots, one on the side, one in the middle, where would the plumule and radicle grow from?

thats cuz we havent tried it yet...

Thses errors should not happen spevially in mark schemes

Their "not entering into discussions" explicitly justifies the fact, they are not brave

they would grow from the middle...check out the picture i posted in my last post..
it clearly shows that plus in my book all the pictures of germination..( not many though) show that first the middle part extends outside and then goes on to divide into radicle and plumule...

yea but still, some pictures do show that plumule and radicle grow from the top. Here there are 2 possibilities and one would not risk in guessing so i want this clarified! Plus, there's no hint in the mark scheme.

well if it came in the paper i would write the center cuz most of the plants grow their radicle and plumule from there...

I got a feeling that the upper part is plumule and the part in the center is radicle, what do you say?

i just said...i dont have a feeling....
plus the one i have is that they both come from the same part...i even checked WIKI!

 

[asd]

If that's so then the middle part's got to be hilum!

The testa is the outer part which contains the small thingy from which plumule and radicle grow out !!

thats what i have been trying to say for a long time now.
thanx for strengthening up my case!!

that i know.
want you to identify the plumule and radicle (shown in q no. 2)

most seeds shown have their embryo on the top!

they are not actually on the top...jab seed grow karte hai to they shift like that k wo top par ajata hai...
let me confirm this from my teacher ok??
jeet gaya bhai tu!!
