Sexual reproduction has played the most crucial role in evolution of plants. The primitive plants
were cryptogames in nature which did not produce flowers, fruits or seeds.These primitive plants
were completely devoid of sexual reproduction and dependent upon reproduction by generation
and dispersal of spores. These were later evolved into phanerogames which produced seeds but
these were still devoid of sexual reproduction. With advent of evolution, the plants developed
more advanced features such as flowers which promoted formation of fruits and seeds. This
simultaneously gave rise to angiosperms and gymnosperms. These evolutionary forms of plants
were capable of performing sexual reproduction primarily by cross-pollination. These plants
slowly increased variation and speciatin in the ecosystem which lead to establishement of many
new species. Infact, with these evolutionary successions, the plants have evolved into their
present form where sexual reproduction plays a most crucial role by establishing multiple types
of species in the history of plant evolution.
Thus, sexual reproduction has evolved many different times and in many differenty types in the
evolutionary history of plants with generating more than 20 plants alone. This states that the
statement is true.
