Explain why cellular respiration adds carbondioxide to the atmosphere, but photosynthesis does not. |
Organisms use oxygen and give off carbon dioxide(CO2) in cellular respiration,but in photosynthesis, plants use CO2 and give off oxygen. |
|
|
How does plant nutrition differ from humannutrition? |
Plants are producers (they make their own food);humans are consumers. |
|
|
How is the equation for cellular respirationdifferent from the equation for photosynthesis? |
The equation for cellular respiration is theopposite of the equation for photosynthesis. |
|
|
Chloroplasts contain a pigment called_______,it’s responsible for absorbing light energy from the sun, and makingphotosynthesis possible. |
chlorophyll |
|
|
In fermentation, what do cells use instead ofoxygen to break down glucose? |

|
What are the chemical products of cellular respiration? |
carbon dioxide, water & ATP(energy |
|
|
Where do plants obtain the needed energy forphotosynthesis? |
the sun |
|
|
What do the respiratory system and respirationhave in common? |
They have oxygen in common. |
|
|
What happens during cellular respiration? |
Cells use O2 to break down glucose(sugar) and release CO2,water and energy in the form of ATP |
|
|
Where in the cell is ATP produced? |
in the mitochondria |
|
|
Explain how cytokinesis and mitosis aredifferent. |
Cytokinesis is the division of cytoplasm.Mitosis is the process in eukaryotic cells in which the nuclear material splitsto form 2 new nuclei. |
