during the evolution of plants, the sporophyte generation becomes dominant. why is this event an adaption to life on land?

Solution

Development of alternation of generation in which the sporophyte is dominant, is a great evolutionary step.

Land plants developed strategies for desiccation tolerance. Development of apical meristem and waxy cuticle have helped plants to survive in terrestrial environment.

Seeds germinate to give rise to the sporophytic generation. The embryo, which forms the sporopyte is contained withn the seed.

The thick protective coat around the seeds prevents desciccation. This also is a step towards freenig reproduction from requirement of a constant supply of water.

Scattering of seeds to far off places by various agentshas helped spread the plant in a vast geographical area.
