Space exploration

[Gulalai]

So many discoveries have come out of space exploration and in today's day in age space exploration continues to expand. In this thread we can share anything (links, images, videos) that all have to do with the past, present or future of space exploration.

This does not make sense. how can the trees survive without oxygen and the boy has an oxygen mask on.

[Adam]

Trees take in Carbon Dioxide and expel Oxyen

[khushal]

how many Earths can fit in a Betelgeuse?

[DaZahroJaam.]

they are able to survive on a lower level of oxygen than human beings. besides, they produce oxygen through the process of photosynthesis while human beings waste it.

Hello Adam,

I know that, but Plants do need oxygen to live, because without oxygen they can't perform aerobic respiration which is the process of breaking down food for energy. when plants perform photosynthesis, they combine water, carbon dioxide, and the sun's energy to produce sugar and oxygen. So the cells in the green parts of the plant, where photosynthesis is taking place, get all the oxygen they need from the oxygen produced by photosynthesis. But the non green area mainly the roots still need oxygen and the plant here on earth get it from airpockets created by worms in the soil. wetlands plants have developed a tolerance for low-oxygen conditions, also they have really shallow root systems so they are as close as possible to the surface. trees that live in saltwater lagoons, have evolved special roots, that act like snorkels for the roots. But most plants don't have these special tolerances and adaptations, which is why you can drown your houseplants if you water them too much.

So in essence you need oxygen. the picture still does not make sense.

what about the fire from the planes, how can they burn fuel with large flames while the boy cant even breath.

[DaZahroJaam.]

they might be carrying oxygen with them. and the force or level is probably strong enough to keep the fire burning on what they already had it started with. and once again, there could be oxygen in there but not enough for a human being to risk brain damage over.

is that how your brain was damaged, lack of oxygen?

[Gulalai]

its true the trees would need oxygen to undergo photosynthesis. dzj is right there would be some oxygen in the atmosphere but just not enough for humans
