A greenhouse (also called a glasshouse or hothouse) is a building where plants such as flowers and vegetables are grown. It usually has a glass or clear (transparent) plastic roof. Many greenhouses also have glass or plastic walls. Greenhouses get hot during the day. It is because the sun's heat warms the plants and soil (dirt) inside the greenhouse and they stay warm through the night, because the heat cannot escape.

Types of greenhouses.

Greenhouses come in many different sizes. Some people have small greenhouses in their backyard, outside their home. Plant companies have large greenhouses. Their structures range in size from small sheds to very large buildings.

Role of green houses.

Many vegetables and flowers are grown in greenhouses in late winter and early spring, when it is still too cold to grow plants outside. Then these plants are moved to the soil outside as the weather warms up. Greenhouses are used to grow crops in cold countries such as Canada. The largest group of greenhouses in the world is in Leamington, Ontario (in Canada), where about 200 acres (0.8 km²) of tomatoes are grown in glass greenhouses.
