Pioneer plants

When we were walking along the volcano, I saw a lava bomb[wiki] that had a tiny green plant growing in it. This may not be very strange to you, but a plant in a large rock is very unusual, don't you think? Anyway, that plant will make a crack, allowing more plants to get in, they break down rocks to make fertile soil (volcanic soil is the most fertile) which will allow even more plants to get in, and then, well, you get the idea.
