When the temperature of the leaf (or any other surface, for that matter) drops below the dewpoint of the surrounding air, water will condense on it. If the dewpoint is below freezing, the water will condense directly into a solid, otherwise known as frost. Something interesting is that the a surface can be colder than the surrounding air, because under the right circumstances it can be cooled by radiation to the sky. Dew formation causes release of significant amounts of latent heat, warming the surface and the surrounding air. As the night begins the temperature can drop rapidly through radiative cooling of the ground, but once dew starts to form the rate of temperature decrease drops dramatically. Therefore, on a fairly clear night with no frontal passage, the dewpoint the evening before is a pretty good prediction of the low temperature the next morning.
Answer In addition to the above, plants also exude moisture which will form droplets on the leaves in the morning, especially when humidity is high. This is called guttation and can be confused with dew (and both phenomena can occur at the same time).
When precipitation falls from the sky, it evaporates from the ground and becomes water vapor (a gas). The water vapor in the air then cools over-night and condenses. The condensation creates small water droplets, a.k.a. dew.
At night, the lack of solar radiation causes surfaces on the Earth to cool. If the surface is significantly cooler than the ambient air temperature, dew will form.
Specifically, a parcel of warm and moist air in contact with the cooler ground will have its temperature reduced to the "dew point temperature". Once air reaches the dew point temperature, saturation is reached and the gaseous water in the air is able to condense back to its liquid form. If the surfaces are below freezing, the water vapor will change phase directly to the solid form (ice). This is called frost.
Dew is formed when moisture in the atmosphere condenses on cool surfaces at night.

You Figure it out wicked good yaself bub!
Indigo plant leaves are used for dying cotton.
Leaves
no leaves do
Smoke, which is a combination or mixture of gases, organic compounds and particulate matter, causes plants to drop leaves and causes epinasty, which is a downward curvature of leaves, due to its ethylene content. Ethylene causes lateral swelling, reduces the elongation rate and, as opposed to normal vertical growth, causes horizontal growth in seedlings. Smoke often contains air pollutants like sulphur dioxide and nitrogen oxides that are also injurious to plants. Carbon dioxide in smoke is beneficial to plants, since it is used in photosynthesis, but the particulates present could coat the leaves and hinder the absorption of light.
A plant lacking phosphorus would show delay in seed germination, purple or red spots on leaves, dark green leaves, and premature fall of leaves and flower buds.
Answer
Pretty sure its night. During the day plants need more water because the sun is out.
Yes, the sensitive plant (Mimosa pudica) closes its leaves at night. This behavior is known as "nyctinasty" and is a response to changes in light and temperature. The leaves reopen in the morning when exposed to daylight.

Bougainvillea plant fall their leaves during a hot day.
Large Leaves will produce more food for the plant because it can absorb more sunlight which during photosynthesis the plant creates food
