Pollination in water hyacinth and water lily
Water hyacinth and water lily are two aquatic plants that rely on external agents for pollination. Let's explore how pollination takes place in these plants.
Pollination by insects or wind
In the case of water hyacinth and water lily, pollination occurs through the transfer of pollen grains from the male reproductive organ (stamen) to the female reproductive organ (pistil). This transfer can be facilitated by either insects or wind.
Pollination by insects
1. Insects as pollinators: Insects such as bees, flies, and beetles are attracted to the flowers of water hyacinth and water lily due to their bright colors and fragrance. These insects visit the flowers in search of nectar or pollen.
2. Mechanism of pollination: When an insect lands on the flower, it may accidentally come into contact with the stigma, the receptive part of the pistil. This transfers pollen grains from the insect's body onto the stigma.
3. Transfer of pollen: The pollen grains on the stigma then travel down the style, a long tube-like structure, to reach the ovary where fertilization takes place.
4. Advantages of insect pollination: Insect pollination in water hyacinth and water lily ensures efficient transfer of pollen between flowers, increasing the chances of successful fertilization. Additionally, insects also benefit from this interaction by obtaining food in the form of nectar or pollen.
Pollination by wind
1. Wind as a pollinator: In the absence of insect activity, water hyacinth and water lily can also rely on wind for pollination.
2. Mechanism of pollination: Both these plants have light and buoyant pollen grains that are easily carried by air currents. When the wind blows, it dislodges the pollen grains from the anthers (male reproductive structure) and carries them to the stigmas of other flowers.
3. Transfer of pollen: Similar to insect pollination, the pollen grains travel down the style to reach the ovary where fertilization occurs.
4. Advantages of wind pollination: Wind pollination allows these plants to reproduce even in the absence of insect pollinators. It ensures a widespread dispersal of pollen, increasing the chances of successful fertilization.
Conclusion
In conclusion, water hyacinth and water lily primarily rely on insects or wind for pollination. The bright flowers and enticing fragrance of these plants attract insects, which inadvertently transfer pollen between flowers. In the absence of insect activity, wind can also carry the light pollen grains from the anthers to the stigmas of other flowers. Both methods of pollination ensure the successful reproduction and continuation of these aquatic plant species.
