alleryAfter double fertilisation, the zygote develops into the embryo while the:
APrimary endosperm cell (PEC) develops into the endosperm
BPEN forms the pericarp
CPEN degenerates
DPEN develops into the seed coat
Answer & Solution
Correct answer: A. Primary endosperm cell (PEC) develops into the endosperm
**Zygote → embryo**; **PEC (with triploid PEN)
→ endosperm** (nutritive tissue for developing embryo).
Endosperm development *precedes* embryo development to provide nutrition.
