Answer:
Explanation:
A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.[1] These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external temperature, protecting its contents in cold weather.[2]
Many commercial glass greenhouses or hothouses are high tech production facilities for vegetables, flowers or fruits. The glass greenhouses are filled with equipment including screening installations, heating, cooling, lighting, and may be controlled by a computer to optimize conditions for plant growth. Different techniques are then used to evaluate optimality degrees and comfort ratio of greenhouses, such as air temperature, relative humidity and vapour-pressure deficit, in order to reduce production risk prior to cultivation of a specific crop.
Because it has the ability to get light, photosynthesis would happen. Since it is in an airtight jar, it will use all the CO2 in the jar until all the CO2 is gone and there is only Oxygen left. Photosynthesis's rate will decrease rapidly. After that, the plant will have no more energy since there is no CO2 to allow it to keep with photosynthesis, so it would die off.
I would say the first one a comet. :)
