Holes also allow more sunlight to get through to the leaves below, which maximizes sun absorption and photosynthesis. Adaptation: During the heat of the day's sunlight, most plants open stomata (pores) in their leaves to take in carbon dioxide from the air for photosynthesis, while allowing some water to escape.
The amount of matter is conserved when a substance changes form. When matter changes drastically it is not actually destroyed. This can be tested by weighing all the materials involved in an experiment before starting it, and again after the
