||||
| ... is an organism that cannot make its own food. | a heterotroph
🗑
|
||||
| what is the first step of photosynthesis? | capturing the sun's energy.
🗑
|
||||
| what are pigments? | colored chemical compounds that absorb light.
🗑
|
||||
| What is chlorophyll? | it is the main pigment in chloroplasts.
🗑
|
||||
| what is step 2 in photosynthesis? | step two is to use light energy to make food for the cell.
🗑
|
||||
| what are the stomata? | tiny openings on the undersides of the leaf from which carbon dioxide enters the plant.
🗑
|
||||
| what is the photosynthesis equation? | 6CO2 + 6H2O →C6H12O6+602
🗑

🗑
|
||||
| what is the process of obtaining energy from cells? | respiration
🗑
|
||||
| what happens during the first stage of respiration, and where? | the molecules of glucose are broken down into smaller molecules int he cytoplasm
🗑
|
||||
| what happens during the second stage of respiration, and where? | the molecules are broken down further in the mitochondria, using oxygen, which provides a lot of energy.
🗑
|
||||
