Question

what is the exact defination of greenhouse?

Answer 1

Greenhouse may be defined as a structure having transparent walls and roofs made up of glass which is used for cultivating and protecting the pants. The roofs and walls allows the sun rays to get inside the room but restrict its passage to go out of the room resulting in the increase of temperature inside the room. Thus, the plants can be cultivated inside a close glass room providing it with required heat, light and temperature.
