Pick out the wrong statement pertaining to 'green house' for the plants.

'Green house' (made of glass) allows visible sunlight (i.e., short wavelength solar radiation like ultra-violet rays) to pass through the glass and heat up the soil thereby warming up plants inside it.

The emitted longer wavelength radiation (e.g., infrared) is partly reflected and partly absorbed by the glass of the green house.

'Green house effect' in earth's atmosphere is due to increasing CO₂ level in atmosphere. where CO₂ acts like the glass of 'green house' thereby warming up the earth's surface.

'Green house' is colder than the outside atmosphere.
