Would plants grow taller on the moon? Yes, I know there is no air on the moon. It would be in a greenhouse or something. Would they grow a little taller, six times as tall, or about the same?

It is more probably that plants would grow wider in lower gravity, assuming they were lit from above (such as by the Sun), because the wider a plant is, the more sunlight it can absorb.

The limiting factor on horizontal growth is the strength of the plant stems. The further from the center the leaves are, the greater the stress on the stems. In a reduced-gravity environment, the stems would have a smaller load and could therefore grow longer.

Growing plants on the moon is very complicated. A simple green house would be impossible because the CO2 would soon be exhausted unless you had a human their or constantly replenished it. However, if the conditions were right, it is very probable that plants would grow taller on the moon, because they have less gravity pulling them down. Their height however, would also depend on many other factors, such as the amount of lighting they were receiving in the greenhouse, and the thickness of the air in the green house.

Seems have a big turn in a person's life. The external form of a person is ideal in the eyes of the planet when every feature is assembled in flawlessness or very nearly there. Of all of them, height represents an important role.
Height is not just lots is one of the critical standards in plenty of areas: sports, being a part of the security force, wooing someone, obtaining a work or just bolstering one's assurance therefore, if you want to be slightly taller you just have to use this program https://bitly.im/aL8Dl , grow taller 4 Idiots.
The combination of proteins with growth hormones, could certainly lead to a taller stature and this really is what you would study on this book, how you can set this mixture used because this system really work for nearly all people.

Very good question. Unfortunately the answer is a bit complicated. Essentially, the growth of any multicellular organism, such as a plant, depends on several things, notably:
- how large the cell will be before they divide
- how many divisions will cells go through before the organism stops growing, and just maintains its maximum size
- how much does gravity affect the size and shape of the plant
- will the plant have optimum water, sunshine and nutrients
- what environmental threats will the plant face (pests, freezing, etc.)
- how much competition will the plant face for resources?

I believe that most plants have their sizes limited by their genetic potential, and the requirements for growth such as sun, water and nutrients. However, over time, plants can evolve to reach different heights, but only if doing so offers it a competitive advantage or otherwise improves its chances of survival.

Well if the plant is in a green house then it is growing in the same atmosphere as if it were here on earth. The result would be the same.

I think its a good question.

So lets think about it a little bit.

What makes a plant grow.

Water and Heat or light.

I dont think it would matter where you put it. If the green house is in the bottom of the ocean the plants would be in the same environment inside the green house.

Plants would not be bigger but be the same.

..."When the Apollo astronauts explored the Moon, scientists attempted to grow seeds in the lunar soil that was returned to Earth"...."The lack of gravity -- essential for plants to develop strong rooting, sunlight, available nutrients, insects (for cross pollination), controlled climate and clean water are all challenges for astroculture."..."Fans are necessary to provide air movement in space, since there are no natural wind currents like on Earth. Without air movement, space plants can suffocate on the oxygen they exhale! "...

Assuming all environmental circumstances for enhance have been met on the moon (tremendously enormous assumption!), then i think of it would advance with reference to the comparable because it does in the international. relies upon extra on the genetics of the seed than on gravity.

It's not that there's no air -- there's no CO2, which is what plants breathe.

Therefore, they'd suffocate before they could get started.

No they would not.. even in a green house!! dont you think they would have done it already!?!?!

Why the hell would they, even if there was air?
