In sexual reproduction, new plants are produced from seeds.
Two plants are not always necessary for sexual reproduction. In bisexual flowers, there are cases where pollen lands on the stigma of the same flower (self-pollination), and then fertilization takes place.
Pollination is the process of transfer of pollen grains (which contains male gametes) to the stigma of a flower (the female reproductive part consists of stigma, style, and ovary which contains the female gametes). This process allows the contact between male and female gametes, leading to fertilization. Hence fertilization can only take place after pollination.
Pollination can be caused by different agents such as wind, water, insects etc.
