During the daytime. There are many factors that contribute to this, but four main ones are humidity, wind, temperature, and sunlight. When plants make their food through photosynthesis, they end up producing CO2. They release this by opening the stomata in the leaves. This forces the plant to transpire as the sun evaporates the water. Also, the temperature plays a major role. The warmer the temp. is, the faster the water will evaporate out of the pores. As for humidity, something in a drier area will be able to release its moisture than it would be in a damper area. This is diffusion- think of it as a sponge on a paper vs. a bowl of water. The wind simply helps with this because once the plant releases its moisture into the air, the wind brings drier, less damp air around the leaf.
Green plants give out oxygen in the day time and take carbon dioxide and during the night the green plants give out carbon dioxide and take oxygen.
Above plants can uptake CO{-2} during the night as well because of their ability to perform a type of photosynthesis called Crassulacean Acid Metabolism (CAM).
In most green plants the stomata are only open during the day. They allow carbon dioxide to reach the cells where the majority of photosynthesis takes place. As they also allow transpiration (water loss) the stomata of most plants close during the night when photosynthesis is not possible. There is a group of mainly desert plants known as CAM plants. These carry out a process called Crassulacean acid metabolism, which effectively allows them to store carbon dioxide in their leaves. In these plants the stomata are normally closed during the day to prevent water loss when temperatures are high, and open during the night when temperatures are lower.

In general, green plants photosynthesize during the day or when light is on the leaves, and respire at night, or in the dark. As its name implies, photosynthesis is a light dependent process.

No.
Pretty sure its night. During the day plants need more water because the sun is out.
Cam plants close during the night and open during the day because they are photosensitive and respond to light. To do it experimentally, try with a torch for some time.
