The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Angiosperms**: Angiosperms are flowering plants that reproduce through seeds enclosed within a fruit. They have distinct male and female reproductive organs. 2. **Identifying Male and Female Organs**: In angiosperms, the male reproductive organ is called the androecium, which consists of stamens. The female reproductive organ is called the gynoecium, which consists of carpels or pistils. 3. **Structure of the Stamen**: The stamen, the male part, has three components: - Anther: where pollen grains are produced. - Filament: supports the anther. - Connective: connects the anther to the filament. 4. **Pollen Formation**: Inside the anther, pollen grains are formed through a process known as microsporogenesis. 5. **Structure of the Carpel**: The carpel, the female part, has three components: - Stigma: the sticky surface where pollen lands. - Style: the tube that connects the stigma to the ovary. - Ovary: contains ovules where fertilization occurs. 6. **Pollination Process**: After pollen grains are formed, they are released from the anther. Through various modes of pollination, pollen grains reach the stigma of a compatible flower. 7. **Pollen Germination**: Upon landing on the stigma, if the pollen grain is compatible, it germinates. This means it begins to grow a pollen tube down through the style towards the ovary. 8. **Conclusion**: Therefore, in angiosperms, pollen germinates on the stigma. ### Final Answer: In angiosperms, pollen germinates on the **stigma**. ---
