Photosynthesis: An Introduction To The Process Of Photosynthesis

Introduction: What is photosynthesis, photosynthesis is the process where light energy is converted to chemical energy and storing it in chemical bond of sugar all these reactions take place in structures called chloroplasts. During the process of photosynthesis carbon dioxide, water, and light is consumed to produce glucose and oxygen. Thus bringing us to cellular respiration this is where plants consumes glucose and oxygen and produces carbon dioxide, water, and ATP energy molecules. To capture light energy for photosynthesis, chloroplasts absorb all light in the violet/blue and orange/red wavelengths. Almost all green/yellow light is repelled, which is why plants appear to be green. There are three pigments that are used during photosynthesis to
1. First we pour 10mL of infiltration solution and 30mL of sodium bicarbonate in a small beaker.
2. We obtain 4 10mL syringes with it plungers removed.
3. During this process we also used soda straw to cut out 40 leaf disks from spinach leafs and inserted 10 disks of spinach leafs into each syringe and carefully inserted the plungers back into each syringes.
4. After that we inserted the tips of the syringes to the beaker of solution that we had and drew up 8mL into each syringes, flipping the syringes so that the tip is upward, we depressed the plungers to remove any air in the syringes without compressing the leaf disks.
5. Sealing the tip of the syringes with our finger we pulled back on the plungers that took air out the leaf disks, we repeated this processes until every leaf disks in each syringes stop floating.
6. Next we set the syringes, tip up, in front of the lamp that was assign to us, which was a white light bulb. At 1 minute interval we would flip the syringes to see how many leaf disks were floating and record it. We repeated this processes until all leaf disks were floating
