Can anyone explain? i just got to thinking about how earth is extremely over populated and will be even more soon so like we really need to start thinking about other planets. i know you need water for the plants so ya...that could be a problem

I remember reading a story about this back around 5th grade (I'm 52, so that was a long time ago). People were trying to make Mars habitable, so they planted trees. In the story, the trees grew VERY fast, and provided oxygen.
One thing that could be a problem (besides lack of available water) has to be the temperatures on the surface of the planet. Mars has a much thinner atmosphere than earth, and that means great extremes of heat and cold. But who knows? Some day a genetically engineered plant just might do the job!

Plants need oxygen, liquid water and nitrogen. The lack of oxygen will kill a plant just as much as it kills you. The plants need water to live, and there isn't any liquid water that is accessible. The lack of nutrients in the soil will starve the plant. But the atmosphere on Mars is too thin anyway. It may be mostly carbon dioxide, but a large portion of a small value is still a small value.

Plants don't only need water, CO2, and sunlight to survive...they also need nutrients...something in which the Martian soil lacks. It would also take a stable climate, but the Martian climate has too many extremes in temperature for plants to adapt...genetic engineering may be the best approach to overcome that problem, but it will not solve a plant's need for water and nutrients. I'm sure when we find a way to efficiently solve those problems we'll turn Mars into an oasis for life, but the cost of doing it now would be too great on society to make it feasible.

no longer each and every of the time. At evening flora relatively take in oxygen and supply off CO2. it truly is via the fact they're breaking down that sugar to get skill for advance and mixing different factors, minerals, and chemical ingredients for making flora, fruit, seeds etc. they're doing an identical situation in sunlight hours too, yet photosynthesis is so effectual that the plant makes use of up the carbon dioxide because it makes greater sugar than it relatively desires so there is an much better than oxygen, it is released.

The problem comes in getting the plants there, and then getting them to survive. And that making Mars livable for humans (terraforming is the scientific term for it) will take years. It's something that people are working on the idea for, but not the execution.

It's a bit chilly for most plants. The absence of surface water might also be a problem.

VERY low atmospheric air pressure. there isn't anywhere near enough CO2 to allow a plant to live.
the coldness plays a part, but plants grow on earth in places where it is colder than parts of mars

no water and a big temp difference between night and day and the soil is not good to be planted,,,
y dont we plant the earth, it's easier and it's helpful for the environment, right???

The water hose would cost to much.

seeds need oxygen to germinate
