The process by which plants make food is called "photosynthesis". The word "photosynthesis" is made up of two words:
Plants take in carbon dioxide from the air and water from the soil; put them together (in the presence of light energy and chlorophyll) to produce sugar (glucose) and oxygen.
Chlorophyll is the green pigment found in plants. Both chlorophyll and light energy need to be present for photosynthesis to take place, but they are not used up in the process.
Thus, the process of photosynthesis can be represented as follows:
carbon dioxide + waterchlorophyll
→→→→→→→→
light energysugar (glucose) + oxygen
Some of the sugar produced during photosynthesis is used by the plant for its life processes (such as growing and reproducing); the excess is converted mainly to starch and stored in various plant parts which may be used as food by animals and humans.
Oxygen produced during photosynthesis replenishes the oxygen that was used up by living things during respiration ... mouseover the above picture for more information on respiration.

An organ system typically consists of multiple organs working together to perform specific functions. The number of organs in an organ system can vary, ranging from a few to many, depending on the complexity of the system. For example, the digestive system includes organs such as the stomach, liver, and intestines, while the respiratory system includes organs such as the lungs and trachea.
All of them.
dunno :P
veins and the heart.
organs and other stuff that i forgot about:)
The major organs that make up the reproductive system is the penis in males and the vagina in females. The other organs are the gonads, more specifically the testicles and ovaries.
A system, such as the digestive system, is composed of several organs. The digestive system includes the stomach, the small intestine, the large intestine, the liver and the pancreas, and a few other organs.
Cancerous cells can also invade other organs through the circulatory system of the lymph, causing those organs to malfunction.
The main organs of the circulatory system are the heart, blood vessels and blood. The blood vessels include arteries, veins, and capillaries.
The circulatory system transport the nutrients that help build up other organs.If for some reason the circulatory system get disordered,the nutrients wouldnt reach the other organs which will cause the other organs to malfunction and eventually stop doing their specific work. Wrote By: LB
