Advantages of seed formation in plants:

• Seeds provide a protective coat so that the embryo plant can develop when it finds a nice piece of soil.       
• Seeds are a protective structure that lets a plant embryo survive for long periods of time before it germinates. The seed can remain dormant until conditions are suitable for the embryo to begin growing.
• Seeds have food sources pre-packaged for plant embryos to provide for an embryo's needs in early growth.
• Seeds are easily dispersed by animals, wind, birds etc, so the plant can colonize a large area. Some are even so lightweight that they are carried across the planet by strong winds.
• Seeds can survive without water, so if there is a drought the plant can survive. 
• Seeds are produced in large numbers so plants can multiply.
