Not too sure if its correct but I think its because plants are unable to move on their own in order to get the pollen grains from their anthers to the stigma of another flower for pollination, therefore the rely on external factors.
Pollination can occur through wind, animals (such as bees, butterflies, and birds), and self-pollination (where pollen is transferred from the anther to the stigma of the same flower or a different flower on the same plant).
Pollination is the transfer of pollen from the male reproductive organ (anther) to the female reproductive organ (stigma) of a flower, typically facilitated by animals, wind, or water. Fertilization occurs when a pollen grain germinates on the stigma and the pollen tube grows down to the ovary, where it fuses with the egg cell to form a seed. This process is essential for sexual reproduction in flowering plants.
Plants encourage cross-pollination by producing attractive flowers that entice pollinators like bees, butterflies, and birds to visit and transfer pollen between plants. Some plants also have structures that make it difficult for the same plant to pollinate itself, further promoting cross-pollination. Additionally, plants may release scents or nectar to attract pollinators, increasing the chance of pollen transfer between different plants.
Bees help flowers make babies by transferring pollen between them.
No, fertilization in plants typically occurs after pollination. Pollination is the transfer of pollen from the male reproductive organ to the female reproductive organ of the same or a different plant, leading to the eventual fertilization of the ovule. Therefore, pollination is a necessary step for fertilization to occur in most plants.
Plants reproduce by pollen grains. There are 2 types of pollination: Cross pollination and Self pollination. They are primarily pollinated by means of wind pollination or insect pollination.
Pollination means transfer of pollen grains from anther to stigma in plants.
Male and female parents. The pollen is transferred from male to the female parent.
No, pollination occurs in plant cells of the flower, particularly in the male reproductive parts such as the stamen. Root hair cells are involved in the uptake of water and nutrients from the soil and do not play a role in pollination.

Self-pollination occurs in a variety of plant species, particularly those with perfect flowers that possess both male and female reproductive organs. It is most common in plants such as peas, beans, and many types of orchids. While exact numbers can vary, it is estimated that around 20-30% of flowering plants are capable of self-pollination. This strategy can be advantageous in stable environments where pollinators are scarce.
Pollination. Pollinating with two plants is Cross Pollination. Pollinating with one plant is called Self Pollination.
