Man Takes Up Internal Farming
RockDoctor writes "'A Massachusetts man who was rushed to hospital with a collapsed lung came home with an unusual diagnosis: a pea plant was growing in his lung.' Just that summary should tell you enough to work out most of the rest of the details, but it does raise a number of questions unaddressed by the article: How did the pea roots deal with the patient's immune system? What would have happened if the situation had continued un-treated? I bet the guy has a career awaiting him in PR for a pea-growing company."
There is a similar case of a pine tree in a lung.
Ceci n'est pas une signature.
...not to inhale my food. Guess she was right.
a 'Lung'gume.
Hmmm Hmmm. see what I did there.
Seeds don't need light when they're just sprouting. That's why you can plant them buried under soil, then they start to sprout.
Think of it as them subsisting on their "egg yolk" (the twin "bean" parts) while they're still in the process of sprouting. As the plant use them up in sprouting and forming leaves, the "bean" parts shrivel up and then the plant starts to rely on its roots and leaves for food and water.
What the article describes most likely looks more like a bean sprout than a full-blown pea plant.
visit my pal the xkcd explainer!
A seedling is capable of germinating without sunlight, because the fruit (the pea) has within it all the necessary nutrients to sprout.
Photosynthesis serves the function of producing sugar from sunlight, water, and carbon dioxide by transfering an electron through several enzymatic structures. It is conceivable that (in order of likelihood), a) the half-inch long seedling was still being fully fed from the fruit, b) simple diffusion of sugar from the blood stream was able to supply the plant with enough sugar to sustain itself, c) free radicals were able to diffuse into the seedling's tissue, donating an electron to the photosynthetic chain.

...he's achieved inner peas?
Modding "-1, Troll" is not a proper response if you disagree with me. Try reason.
