Answer:
The correct options are:
There are million of spores that are made by a single plant to help keep its population.
Spores can live for a long time without maturing into an adult plant.
Step-by-step explanation:
Spores can be described as a means of reproduction in plants like the gymnosperms.
There are millions of spores produced by a single plant so that the chances of their dispersal and maturing into new plants is maximum.
Spores also have the capability to stay dormant until the conditions become favorable for the growth of a plant from the spore.
Another adaptation of spores is that they are light weight so that they can easily be carried away by the wind.
