Statement 3 is incorrect.
Changes in the environment especially due to anthropogenic activities have limited the population of pollinators (such as Bees). In such a situation, plants evolve to self-pollinate itself.
What is Self-pollination?
It is a reproductive process in plants where pollen from a flower’s male reproductive organs (anther) fertilizes the female reproductive organs (stigma) of the same flower or another flower on the same plant.
The mechanism ensures the plant’s ability to reproduce without relying on external pollinators like insects or wind.
Mechanism of the Self-Pollination:
- Anther and Stigma Proximity: In self-pollinating plants, the anther (producing pollen) is close to the stigma (receiving pollen) within the same flower.
- Pollen Transfer: Pollen grains are transferred from the anther to the stigma, either by physical contact or through the plant’s internal mechanisms.
- Fertilization: The pollen tube grows down the style to the ovary, where fertilization takes place, resulting in the formation of seeds.
- Genetic Similarity: Since both the pollen and the ovule come from the same plant, the offspring are genetically identical to the parent, leading to limited genetic diversity.
Self-pollination ensures reproductive success, especially in environments with limited pollinators, but it can also reduce genetic variability in plant populations and risk to the plant-pollinator interaction system.
