How does a tiny little seed grow into a massive tree or plant？
In: Biology
The same way a tiny human embryo (a seed is just a plant embryo) grows into a full adult human: They consume stuff from their environment use it as building material. When we eat food, our bodies break it down and use it to build more cells. Similary, trees take in water, carbon dioxide, and nutrients from soil, and with help of sunlight, turn it into more stuff to grow.
