Question

Rest options are
3. provides some characters of male plant to endosperm
4.All of the above
Ans is 4....how??
I think 2nd is wrong bcoz endosperm is formed before embryo formation.

Answer 1

no 2nd is not wrong..
after fertilization the 2nd gamete fused with secondary diploid nucleus to PEN .
hence endosperm is formed after fertilization and simultaneously double fertilization we can say..

Answer 2

hi dear!!

yes you are right that  endosperm is formed before embryo formation.

but here "ensures formation of endosperm only after fertilisation" ..in this i think "fertilisation" term refers to double fertilisation and not syngamy.so the statement is correct becoz endosperm develops only after double fertilisation.

hope this helps!!!!
