Question 1 Report
In demonstrating the importance of mineral elements in plants, the culture bottle must be darkened to?
Answer Details
The culture bottle must be darkened to prevent photosynthesis in the root. This is because photosynthesis in the root can lead to the production of oxygen, which can cause oxidation and breakdown of the mineral elements. By darkening the culture bottle, the root is deprived of light, which in turn prevents photosynthesis and ensures the mineral elements remain intact. Additionally, preventing algal growth in the culture solution may also be a reason to darken the bottle, but the primary reason is to prevent photosynthesis in the root.
