Since plants thrive on Co2 could they survive in temperate areas of Mars?

There have been highs in the 80's fahrenheit recorded on Mars, but those are unusually hot temperatures, and at night it's very cold. In addition to CO2, plants also need water (which would freeze at night), and a minimum air pressure, to allow the plant to draw water up through it's leaves... Unfortunately, Mars has such low air pressure (less than 1% as Earth's on the surface) that this wouldn't be possible.
In addition, the soil on Mars is believed to have several kinds of salts at the surface - which is also bad for plants; so, you couldn't really pull dirt into a habitat and grow anything - at least, not without treating the soil first.

See a 2010 paper in the journal Astrobiology, entitled "Survival potential and photosynthetic activity of lichens under Mars-like conditions: a laboratory study," by J.P. de Vera and several other scientists working in Germany. You may be able to get this through interlibrary loan at a university library.

They would also need WATER. None on Mars.

There is still not enough of it
Of course, if it were Colonised, Humans are good at producing CO2

Plants only inhale CO2 during the day and exhale Oxygen but at night they inhale Oxygen and exhale CO2.

No - plants need oxygen as well as CO2 and there isn't enough. Even at the equator, the night time temperature is cold enough to damage plants.
