In adaptation of plants to life on land did spores or gamete

In adaptation of plants to life on land, did spores or gametes evolve as the reproductive products for long-distance dispersal, and why? Gametes: Gametes are motile and can swim long distances. Spores: Spores are smaller and lighter than gametes. Gametes: A gamete can grow into a new gametophyte, establishing a new individual. Spores: A single spore, but not a single gamete, can establish a new individual.

Solution

Answer:

Spores: A single spore, but not a single gamete, can establish a new individual.

A spore can germinates and develop into an individual whereas a gamete can not develop into an individual without the union of egg.
