Botany and Space: When plants are grown without gravity, how is tropism effected?

Question

If plants are grown in space such as on the ISS, are tropism movements different? Do their roots form differently? Do their blossoms unfurl differently? I would love links to images and any articles about gravity and plant growth if possible.

Answer 1

"Plants do grow in space, but some have shown unusual responses to zero-gravity. The root cells of some plants were observed to have changes in their chromosomes. Interestingly, the measured root production in these plants was markedly faster in space than in the same plants on Earth."

Answer 2

I only have opinions, not facts, but I believe it would nurture randomness... I'm very intrigued by the effects on something such as some philodendrons, pathos, vines/ivies, bromeliads whose orientation to gravity and varying hanging/climbing growth habit already seem adapted to growing on branches that often fall to moist, nutrient-rich forest floor.

Answer 3

you're suggestions-blowing, flowers enhance far off from gravity and in the direction of mild. devoid of gravity, the seeds won't incredibly be responsive to which thank you to start starting to be, and maximum probably die. i think seeds could desire to get fortunate and enhance the miraculous way. in case you have already got a plant, the gravity won't count number as much as mild does,so it will enhance in the direction of mild.
