What is the seed a crucial development in plant evolution?
a. the seed ended the plants dependency on water
b. the seed protects the embryonic plant until conditions
c. the seed allowed plants to grow thicker and taller
d. the seed protects the male and female gametophytes so fertilization can occur

a. the seed ended the plants dependency on water

Explanation:

Seeds are the structures with a protective seed coat and carry the embryo along with stored nutrients in it. The evolution of seed habit in plants allows them not to depend on water for reproduction.

The seedless plants require water as a medium to bring their gametes in the vicinity for fertilization. On the other hand, seed plants such as gymnosperms and angiosperms produce pollen that carry the male gametes to a great distance with the help of natural pollinating agents.
