seeds, fertilization in flowering plants..

Postby isabell » Wed Mar 01, 2006 4:51 am

fertilization in flowering plants ocurrs:
on the stigma
in the style
in the ovule
i the anther
none of the above

i think it is in the stigma where the pollen is deposit not sure..


seeds consist of a:
a) seed coat, plumule, cotyledon
b) hypocotyl, epicotyl, cotyledon
c) radicle, plumule, hypocotyl
d) epicotyl, coleoptile, prop roots
e) seed coat, true leaves, cotyledon




and this one i just need to confirm im right after lots of reading and researching i got this answer: a, i know seeds consists of seed coat, and i think cotyledon (the seed leaf for embryo of a flowering plant)
a little help please!!

fertilization - in ovule.
It happened with me 2 , 2 yrs back. :oops: :o

I created a joke and i remebered it forever...its just like fertilization on cervix for humans! :lol:Then the zygote just fall out of mothers body... a no use process!!! :lol:
Both fertizations involve a tube- fallopian tube [ site of fertilizshn] and there pollen tube [ not site, but conveyer of 2 sperms]...

About seed, a, b & c all appear correct to me!
lets find some botnybuddy who can help us out.

I believe that the answer would be a) seed coat, plumule, cotyledon
