Are stomata normally open or closed during the night?

Open

Closed

Why does the rate of transpiration increase if the light intensity is increased?

The root hair cells become more permeable to water, letting more water into the plant.

The humidity increases, which makes the rate of transpiration increase. 

The stomata open wider to let more carbon dioxide into the leaf for photosynthesis.
