On this basis plants are classified as 1. long day plants, 2. short day plants and 3. day -neutral plants.

On the first day God created Light. Light is divided from darkness, creating Day & Night. Genesis 1:3 The confusion usually lies in the fact that on day four, He then created the sun. "...Then God made two great lights: the greater light to rule the day, the lesser light to rule the night." Genesis 1:16 It sounds confusing, but it's not. God needed to create light first, otherwise the sun and all the stars would have nothing to give off, because the substance of light would have not yet been created.
