What is the chemical equation for photosynthesis? | 6CO2+ 6H2O + light energy ---> C6 H12 O6 + 6O2 |
What is the equation for photosynthesis in words? | carbon dioxide + water + light energy ---> oxygen + glucose |
What is the chemical equation for respiration? | C6 H12 O6 + 6O2 ---> 6CO2 + 6H2O + energy |
What is the chemical equation for respiration in words? | glucose + oxygen ---> carbon dioxide + water + energy |
What are 3 reasons we depend on photosynthesis (3 we discussed in class)? | 1- To make food for plants to survive 2- Uses CO2 we exhale 3- Releases oxygen into the air |
What is respiration? | A process that breaks down food & releases energy. |
What causes the stomata on leaves to open? | Water fills it forcing the guard cells to bend & break open. |
When are stomata usually open? | During the daytime. |
