Which of the following materials are recycled in Photosynthesis and Cell Respiration?
H₂O, O₂, Glucose, and Sunlight
H₂O, O₂, Glucose, and ATP
CO₂, H₂O, O₂, and Glucose
CO₂, H₂O, O₂, and ATP
Which of the following are products of Light Dependent Reaction?
ATP and NADPH
ADP and NADP
Glucose and Carbon Dioxide
Oxygen and Carbon dioxide
Why does the Light dependent reaction happens before the Calvin cycle?
Because plants are more active during the day than at night.
Photosynthesis happens faster when there is sunlight.
The products of the light reaction are important to the fixation of Carbon dioxide
More products are formed during the day.
Which of the following statements show the importance of Photosynthesis in the environment?
Plants produce oxygen during day time and perform transpiration.
Plants help stop climate change by trapping heat from the environment.
Plants reduce ozone layer depletion by preventing the negative impacts caused by CFCs.
Plants absorb carbon dioxide that contributes to the rising of the earth’s temperature.
