How did that that fir tree seed sprout inside a mans lung?
That seed was in an ideal place to grow. It has water, as the lung tissue is slightly wet, and had plenty of oxygen. So the biggest issues that you should worry about is soil and light. Well, why does a plant need soil (or fertilizers)? Soil is the nutrient source for the plant. Well our bodies have to feed the lung cells as well, so nutrients are flowing throughout our body, this little tree would just have to take them from its host. Now for the big question, what about light? Plants need light to live, right? They live by photosynthesis? Think about most seeds you have seen, did they have leaves? No. So the first stages of growth for a plant does not require photosynthesis. In fact, the seed has all the nutrients and sugars need for a sprout to form. But what about after sprouting, the plant has to have light then, right? No. Just like mammalian cells, plants also have mitochondria, and they can convert fats and sugar gotten from elsewhere and use them as a fuel source. Photosynthes
