In order to be able to regulate heat and humidity. Insects can also be dealt with in a more controlled fashion.
Plants grow better in a greenhouse. My grandma owns one and they grow much better in a greenhouse.

A greenhouse is made of glass and you put plants in it. The sun's energy shines through and some is released as heat and is trapped by the glass from leaving. This allows plants to live/grow when the weather outside is too cold for it.
Humorous answer: greenhouse gasses Correct Answer: Carbon dioxide, just like when outside and not in a greenhouse.
you simply use a greenhouse by putting plants in there and water them and then you simpley watch them grow
In a greenhouse the gases in a greenhouse collect the sunlight and trap the heat. This provides sunlight and a warm temperature for plants to be able to grow.
To grow exotic plants (plants not meant for your climate)
A greenhouse is a building used to grow plants, usually plants that aren't suited for the climate where the greenhouse is. Greenhouses are usually very humid and stay very warm, they're ideal for growing tropical plants and flowers, as well as vegetables. They can also be regulated during the winter to grow plants as well, that one would typically have to wait until summer or spring to grow.
People grow plants inside a plastic greenhouse the same way they do inside a glass one. Plastic ones work in the same way and allows plants to grow better than in the outdoors because of the humidity created.
A greenhouse, using the greenhouse affect, does help the plants grow faster. Let me try and put this is simplest terms. Heat, is a measurment of energy. And plants need energy to grow, which is why they need heat to grow. The sun emits radiant energy. Radiant energy is pretty much heat that is transferred through an empty gap, like space. ( this does not inclue air ). Radiant energy can transfer through the glass/plastic of the greenhouse and gets obsorbed by the plants. Then the plants emit their own radiant energy, except it is not the same as the energy it took in. The radiant energy the plants inside the greenhouse emit can not penatrate through the glass/plastic of the greenhouse, trapping all heat inside.
Because they have the same effect as a greenhouse. They trap heat inside them, just like a greenhouse does to help the plants grow.
Carbon dioxide helps the greenhouse in one way. Plants in the greenhouse needs carbon dioxide to grow.
