Question

Evolutionarily significant elements of seeds are: 1 - Protect the embryo II - Provide a source of nutrition for the embryo III - Seed numbers often times exceed the numbers of spores found in the microenvironmer IV - Seeds can stay dormant for long periods of time V - Seeds will often only germinate when conditions are favorable O I, II, IV and V II, III, IV and V I, II and III I and II

Answer 1

Following are the main purpose of seed adaptation-

1) allow embryo to survive in an environment that might kill the plants

2) maintain dormancy under unfavourable conditions and prevent the development of plants until favourable conditions are not achieved

3) helps in dispersal of embryos

4) store food

5) provide protection to young plants

So options I, II, IV, and V (option A) is correct
