AThe pollen tube enters the antipodals directly
BThe vegetative cell directly fuses with the egg
CThe pollen tube germinates through a germ pore, grows through the stigma and style, enters the ovule via the micropyle, and discharges two male gametes into a synergid
DThe egg leaves the ovule to meet the pollen tube
Answer & Solution
Correct answer: C. The pollen tube germinates through a germ pore, grows through the stigma and style, enters the ovule via the micropyle, and discharges two male gametes into a synergid
**Pollen-pistil interaction**: compatible pollen germinates → pollen tube exits via a **germ pore** → grows through stigma + style → enters ovule via **micropyle** (porogamy) → reaches embryo sac → enters **synergid** (guided by filiform apparatus) → discharges **two male gametes**.
