here's a photosynthesis song which miss wang showed us today ^^
ENJOY!!~
Questions by Miss Wang (:
1. What would happen if there were no photosynthesis?
Own theory:
If there isnt photosynthesis, we living things would have no oxygen to breathe in and instead, at night, we had to compete with the plants for oxygen. There would be a increasing degree of global warming and The population of the living things would slowly decrease and we will all be extinct.
Better theory:
-

2. Why is photosynthesis important for plants only?
Own theory:
Photosynthesis is important to plants because plants do not feed on other foods but they make their own food through photosynthesis. Without which, plants will die and this will also affect the other living things.
Better Theory:
-
3. A plant needs its food to function. It cant really make its own food at night. Beyong a few hours of darkness, can a plant stay alive without light?
Own theory:
Yes, plants can grow in the dark but they have to be in the right spot. They grow better in the sun. Another thing they may not grow in the dark but they still survive. Plants have a thing in them to store food in case there isnt sun for a few days. Plants like cactus have a thing in them to store water and food.
Better theory:
-
WE CANT FIND A BETTER THEORY THROUGH UNCLE GOOGLE, COULD YOU HELP US? THANKS !

Wondering Why is it like this!?
Questions:
1.Why oxygen combined with oxygen?

2.Why H2O combined with CO2?

3. Why C6H12O6? Why had to be this few numbers but not the others?

4. Why only plants have chlorophyll and they photocynthesis? Why human doesnt need any of them?

5. Why some plants are not green and they still are able to photosynthesis? Isnt the chlorophyll making the plant look green?
