This week we finished up respiration and photosynthesis. We also started(and ended) fermentation, and started DNA.
We discovered that the products for respiration are the reactants for photosynthesis and the reactants for photosynthesis are the products for respiration. We then drew a chart that shows how plants are a recycling system.
We now know that anaerobic, or fermentation, means respiration with out oxygen. "A" means without and "aero" means air, anaerobic. We did an experiment to prove this. We put yeast in sugar water and filled the vile to the top so there is no oxygen. We left it there for a day and checked on it 24 hours later. Some of the water is gone and there is some carbon dioxide bubbles. This experiment was the result of alcohol starting.
DNA was the organelle we strated at the end of the week. It is in the nucleus and controls everything. It stannds for Deoxyribo Nucleic Acid. DNA is just a large molecule with a double helix and base pairs. The back bone is were the sugar is in the DNA.
