Some of these are stupid. number 5. for example it depends on the type of plant. Some can live in complete darkness. some of the plants on the rain forest floor don't get any. I would put True though because I assume she is talking about every day plants.
1. false. they use it to make their food. you can look this up online.
2. Umm I'm not sure about this one. The heart doesn't exactly squeeze blood. It has many functions that allow you to keep your blood flowing. I'd say True because it does make your blood move through the blood vessels. You should get a better teacher he/she sucks.
3. Yes. look here http://www.nelsonthornes.com/secondary/science/sci...
4. False. they are separate organs. if you have a collapsed lung you can still live and same with a heart attack.
5. like I explained above true.
6. False. some cells have more mitochondria because they need more energy for growth
