What makes the seed a successful means of reproduction?

Answer 1

The evolution of the seed enabled plants to resist harsh environments and disperse offspring more widely.For bryophytes and seedless vascular plants, single-celled spores are the only protective stage in the life cycle.

Answer 2

Seeds allow plants to be dispersed over a wider area. Seeds may lie dormant until the right conditions allow them to germinate. Seeds have food reserves (endosperm or cotyledons), which enable a plant to grow strong enough while developing a root system to gain access to deeper nutrients.

Flowers provide a target for pollinators (birds, bees, butterflies etc), and pollinators are a more efficient at fertilising than relying on water ( as the non-vascular, and seedless vascular plants do) to enable fertilisation.

Answer 3

Seeds contain a fertilized egg and some nutrient, wrapped in a protective coating. Seeds can remain dormant until conditions are right for germination. Seeds can be carried to other areas by many different mechanisms.

Answer 4

There are a number of reasons why seed plants are successful. Seed plants are protected by hard shells that allow them to travel.
