Why does the zygote begin to divide only after the division of Primary Endosperm Cell $(PEC)$ ?
The endosperm in angiosperms is formed
If an angiospermic male plant is diploid and female plant tetraploid, the ploidy level of endosperm will be
Enlist the steps of controlled cross pollination. Would emasculation be needed in a cucurbit plant ? Give reasons for your answer.
