Rohan Mallya P8 1/18/11

Today was a half-day, so we couldn't do as much as we should have, for we had a 26 min. period. We went over the homework and an experiment for tomorrow. Here are the answers to the homework:

1. According to your notes, what is the equation for photosynthesis?

6CO2 + 6H2O yields C6H12O6 + 6O2

2. Where do plants get the CO2 for this process (what organisms release this gas) ?

They get carbon dioxide from all living things (Pants also breath oxygen and release carbon dioxide. They only need carbon dioxide for photosynthesis, but they still need to breath.)

3. What organelle in plants is responsible for photosynthesis (producing food) ?

The chloroplasts are responsible for photosynthesis in cells.

4. What is the pigment found in this organelle that absorbs light to power photosynthesis?

It's the chlorophyll.

5. If a plant were under water and was photosynthesizing, what gas would be visibly bubbling from the plant?

Oxygen would.

6. The 2 experiments can vary as long as it tests the two things efficiently. Look online to see what you have to test.

We also went over the experiment. It is in the packet that contains all the questions that were just answered in this blog. We just revised it a little. First off, we have to find the mass of the sodium bicarbonate. Also, we have to add 20 ml. of water to keep the experiment controlled. For today's homework, you have to read the experiment until you can do it without looking at the sheet. You also have to write a prediction on it (Remember: A prediction is not a hypothesis! Look at the syllabus for help.)

Here is a video for photosynthesis (has some things that are hard to understand, but won't disrupt main point of video and won't have to be learned for class): http://www.youtube.com/watch?v=mYbMPwmwx88
