No, Mars, gets half the amount of sunlight Earth does. Which you might not think is a big deal, after all means the equator is similar to a high latitude on Earth. But it does make a difference because it changes the heat flow balance.

Earth's atmosphere is warm enough, through the greenhouse effect, to keep Earth warm, water liquid, trees to grow etc.

Our atmosphere on Mars, if you could magically transport it there, would not be able to keep Mars warm in the same way. Indeed it's a mystery to try to figure out how Mars could have had liquid water oceans in the past. Maybe it had greenhouse gases such as methane to help keep it warm.

If you could give Mars the same atmosphere as Earth somehow - it would not be warm enough for trees to grow even at the equator, except of course inside greenhouses.

It would also need to have three times the mass of atmosphere for the same atmospheric pressure because of its lower gravity.

Terraforming plans for Mars usually involve the likes of large planetary scale thin film mirrors to double the amount of light reaching Mars, or else, greenhouse gases produced on Mars - large scale industrial production of greenhouse gases using materials sourced on Mars itself. The most efficient greenhouse gases are based on fluorine, and would involve mining cubic kilometers of fluorite ore a century on Mars to keep it warm, and hundreds of nuclear power stations to supply the energy to create the gases.

I think myself that terraforming of Mars is mainly an intellectual exercise at present - of value for understanding exoplanets, how our planet works, maybe some time in the future could be used for Mars but can't see it happening in the near future.

The Mars Society of course think it is practical. But their aims are more modest as well as more long term than most suppose. It's not like the Mars trilogy, which fudges the numbers for dramatic effect. It would take a thousand years to get to the point where you have a CO2 atmosphere which trees could grow in, but poisonous to humans (we can't survive when CO2 levels in  the air we breathe go above 1%). So humans would need closed system air breathers.  They think it is possible to then go on and develop an atmosphere with oxygen in it, but at that point the plans get increasingly sketchy.

And there is much that could go wrong. See my
