Parts and their functions

• Pollen grain (परागकण) — Lands on a compatible stigma and germinates.
• Stigma (वर्तिकाग्र) — Sticky surface where pollination happens.
• Style (वर्तिका) — The pollen tube grows down through it.
• Pollen tube (परागनलिका) — Carries the male gamete to the ovule.
• Male gamete (नर युग्मक) — Moves down the tube and fuses with the egg cell.
• Egg cell (अंड कोशिका) — Female gamete. Fusion = fertilisation → zygote → embryo.
• Ovule (बीजांड) — Develops into the seed after fertilisation.
• Ovary (अंडाशय) — Enlarges into the fruit around the seeds.
