Answer:
The correct answer would be d chloroplasts, which can be found in leaf cells of trees.
Chloroplasts are double-membrane cell organelle usually present in leaf cells of a plant.
They are the site of photosynthesis in plants by which plants convert solar energy into sugars. Oxygen is released as the byproduct of the process.
Light reaction of the photosynthesis takes place in the thylakoid membrane. It produces ATP and NADPH and releases oxygen.
Dark reaction takes place in the stroma of the chloroplast in which ATP and NADPH are used to fix carbon (obtained from carbon dioxide) into sugars (glucose).
The overall reaction is:
6CO₂ + 6H₂O + solar energy → C₆H₁₂O₆ + 6O₂
It depends on what kind of solution is referred as 0.65 M. If the solution where the red blood cell is present is hypertonic, the red blood cell will shrink. If the solution is hypotonic, the red blood cell will expand. If the solution is isotonic, the red blood cell will not expand or shrink.
