It's when the seed grows up that it is known as a tree. Nobody calls the "seedlings" as "trees" and no seedling is ever useful because it doesn't produce fruits! You got to grow up!

The size and height of the tree determines how heavily the ground will shake when it falls. The cassava tree falls and not even the pests in the forest are aware. The baobab tree falls and the whole forest looks empty! Such is human life!
