Mass Decrease Mechanism
Explain the decrease in mass of the dark-grown plants. Identify the overall chemical reaction that is taking place in these plant cells and connect it to the cellular process underlying the decrease in their mass.
Dark-grown plants, often referred to as etiolated plants, typically exhibit a decrease in mass compared to their light-grown counterparts. This decrease in mass can be attributed to the lack of photosynthesis, which is the primary process by which plants synthesize their food and increase their biomass.
Overall Chemical Reaction
In the absence of light, dark-grown plants undergo cellular respiration instead of photosynthesis. The overall chemical reaction for cellular respiration can be summarized as follows:
C6H12O6+6O2→6CO2+6H2O+energy (ATP)\text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \rightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} + \text{energy (ATP)}
In this reaction, glucose (C₆H₁₂O₆), which can be stored from previous photosynthetic activity, is broken down in the presence of oxygen (O₂) to produce carbon dioxide (CO₂), water (H₂O), and energy in the form of adenosine triphosphate (ATP)…
