Quite simply, No.
Not yet...
no
no
yes you can its a proven fact
No. The soil on Mars lacks the organic nutrients necessary to grow plants.
we can make an airtight city in which we can grow plants
Water
what are the possible plants that grow in lowland areas
No, because there is no oxygen in space therefore it is not possible to grow plants in the soil on the moon
1. The sunlight is not as strong there. 2. There is no water (found water) on Mars. 3. The air composition is different there. 4. The ground contains none of the nutrients that are necessary to grow plants. If you were an astronaut, and you brought oxygen, a strong flashlight, water and a seed with some soil you would be able to place it there and make it grow but your own oxygen tank would have run out by then, so technically, you cannot grow plants on Mars.
No, because there is no life on Mars, so that wouldn't be possible, all planet Mars can do is erode and grow smaller or bigger.
im not entirly sure but i think it could be possible after years of planting trees and plants, monitoring there growth and useing normal soil from earth to fix CO2 levels in the air creating oxygen and possibly a thicker atmosphere until habitable but it would need a lot of dirt, water, hard work, and determination
