In daylight calvin cycle occurs, in darkness Calvin cycle occurs along with conversion of CO2 into sugar and in extended darkness Calvin cycle stops
Explanation:
During daylight, Calvin cycle takes place within the stoma. In this process, energy obtained from sun is converted and stored into bio molecules namely ATP and NADPH.
During darkness, Calvin cycle takes place but the energy of biomolecules i.e ATP and NADPH is used to convert carbon dioxide into sugar. Prolonged exposure to darkness causes reduction in production of energy molecules. Also, the Calvin cycle stops in extreme darkness for a long period of time.
Solar waves with wavelengths between 160 and 400 nanometers are known as ultraviolet rays and carry higher levels of energy than sunlight. Solar waves with wavelengths between 780 and 1,500 nanometers are known as infrared rays and carry lower levels of energy than sunlight.
Flagella (singular = flagellum) are long, hair-like structures that extend from the plasma membrane and are used to move an entire cell, (for example, sperm, Euglena).
