Sequence of Events in Angiosperm Reproduction

Steps:

• Pollination occurs first, transferring pollen from anther to stigma.
• Pollen tube then grows through the style to deliver sperm to the ovule.
• Fertilization follows, where sperm fuses with egg to form zygote.
• Seed germination happens last, after seed maturation and dispersal.

Why C is correct:

• In flowering plants, pollination initiates double fertilization, followed by pollen tube growth for sperm delivery, zygote formation, and finally seed germination as the reproductive cycle completes.

Why the others are wrong:

• A: Fertilization cannot precede pollination, as pollen must reach the stigma first.
• B: Pollen tube growth requires prior pollination to provide pollen grains.
• D: Germination occurs after all prior steps, not before pollination.

Final answer: C
