A flower's anthers are removed before it matures. Later, pollen from another plant of the same species is dusted onto its stigma and seeds are produced. Which process has been ensured here?
(a) Self-pollination
(b) Cross-pollination
(c) Fertilisation
(d) Tissue culture
(b) Cross-pollination
Explanation: The anthers are removed from the flower before it matures to prevent self-pollination. Pollen is then manually transferred from a flower of another plant of the same species to the stigma of this flower. Since the pollen is transferred from one plant to a flower on a different plant of the same species, the process is called cross-pollination.
