Transcript of Photosynthesis and Laws of conservation of matter and energy

Photosynthesis and Laws of conservation of matter and energy
Terms to know
Photosynthesis
- The process in which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
Law of Conservation of Matter
- The principle of physics that matter cannot be created or destroyed.
Law of Conservation of Energy
- The principle stating that energy cannot be created or destroyed, but can be changed from one form to another.
Law of Conservation of Energy
Photosynthesis
Photosynthesis is when sunlight energy goes into the plant. When the energy is combined with CO and H O the matter is changed when it is turned into glucose and oxygen.
Law of Conservation of Matter
The law of conservation of matter is connected to photosynthesis because matter like carbon dioxide and water go into the plant and, with the help of energy, the plant creates a new form of matter -- sugar, or glucose, and releases the oxygen into the atmosphere that is formed from the carbon dioxide.
Example
One example is the water cycle. Water cannot be created or destroyed. It just keeps going around in a cycle and the water stays the same.
Example
The law of conservation of energy is connected to photosynthesis because in order for the carbon dioxide and water to be turned into glucose and oxygen there must be sunlight energy going into the plant. It takes energy for the oxygen to be released but the energy never goes away. It just changes.
Potential and kinetic energy are both examples of the law of conservation of energy because the energy never goes away, instead it is changed from potential to kinetic and then back into potential.
