Science Class 2-9-11

Today in class, we talked about how if there's a sub, we shouldn't listen to them, we should listen to what's on Mr.Finley's plans. After that, we went over the homework.

1. Which form of energy is especially important for living things? Why?
Chemical engery because the ATP gives the energy to your cells so you can do activities.

2. How is photosynthesis important to life on Earth?
Photosynthesis is important because it provides food for us.

3.What starting materials do cells need for cellular respiration?
Cells need glucose and oxygen for cellular respiration.

4. How are photosynthesis and cellular respiration similar? How are they different?
They are similar because they both help plants and other living things live. They are different because photosynthesis makes the glucose and cellular respiration breaks the glucose. Also, cellular respiration happens in the mitochondria and photosynthesis happens in the chloroplasts. And all living things respirate but only plants photosynthesize.

5. Suppose that in a lab you could remove all the oxygen from a terrarium. What would happen to the plants.
If we removed all the oxygen from a terrarium, the plants would die because as it grows, it needs more oxygen and we don't have that much.

6. In everyday language, the word respiration refers to breathing. How is breathing related to cellular respiration?
Breathing is related to cellular respiration because the carbon dioxide we breath out comes from cellular respiration.

After that, we talked about how the result of anaerobic respiration is lactic acid. If the anaerobic respiration keeps up, so would the lactic acid, and as a result you would get muscle cramps. The glucose from cellular respiration is used for energy, storing for later, and it could be used for the plant's structure.
