Describe how the evolution of seeds decreases a plant’s dependency upon water.
Homework Answers
The evolution of seeds decreases a plant’s dependency upon water because seeds can remain dormant during unfavorable conditions. The hard seed coat prevents the drying of seed and endosperm provides the nutrition until the seed germinates. One the seeds are exposed to favorable environmental conditions, they will germinate.
