EVERYDAY SCIENCE

Detailed explanation-1: -Seeds are made at the base of the pistil, in the ovule. To be pollinated, pollen must be moved from a stamen to the stigma. When pollen from a plant’s stamen is transferred to that same plant’s stigma, it is called self-pollination.

Detailed explanation-2: -A pollen grain on the stigma grows a tiny tube, all the way down the style to the ovary. This pollen tube carries a male gamete to meet a female gamete in an ovule.

Detailed explanation-3: -Pollination : The mechanism of transferring pollen grains from the anther of one flower to the stigma of another flower of the same or different plant is called pollination. The pollen grains can be transferred to the stigma of the flower through wind, water and insects called pollinating agents.

Detailed explanation-4: -Pollen from a flower’s anthers (the male part of the plant) rubs or drops onto a pollinator. The pollinator then take this pollen to another flower, where the pollen sticks to the stigma (the female part). The fertilized flower later yields fruit and seeds.

Detailed explanation-5: -Pollination occurs when pollen grains move from anthers to a reproductively mature stigma. After pollen lands on the stigma, it initiates pollen tube formation. Pollen tubes are channels which grow down the length of the style to the ovules.
