    Photosynthesis: Plant cells vs. Solar Cells Chevon Allen 01/23/2010 SCI-115 Professor Garcia Photosynthesis and the semiconductor-based solar cell are very similar process with different ways of reaching the same goal. In photosynthesis‚ plant cells harness the solar energy of the sun with carbon dioxide to transform water molecules into hydrogen‚ oxygen‚ and electrons. Just like photosynthesis‚ Semi conductor based solar cells harness the solar energy of the sun for the same purposes

Lettuce and spinach become firm and crisp when placed in water because the cells absorb the water‚ and in turn makes the lettuce/spinach bloated with water. 5. If you were to continue this experiment by removing the egg from the water and covering it in syrup‚ what do you think would happen. Explain your prediction
