Question
Explain why glucose made during photosynthesis is required for the absorption of mineral ions by the roots.
Solution
Glucose made during photosynthesis is required for the absorption of mineral ions by the roots due to several reasons:
-
Energy Source: Glucose is a primary source of energy for plants. The energy stored in glucose is used to power various cellular activities, including the active transport of mineral ions from the soil into the roots.
-
Osmotic Balance: Glucose helps in maintaining the osmotic balance of the cell. It is converted into osmotically active substances, which helps in the absorption of water along with mineral ions.
-
Synthesis of Organic Compounds: Glucose is also used as a building block for the synthesis of other organic compounds required by the plant, including amino acids and nucleotides, which are essential for the growth and development of the plant.
-
Proton Pump Activation: The energy from glucose metabolism activates proton pumps in the plant cell membranes. These pumps create a proton gradient that drives the active transport of mineral ions into the plant.
In summary, glucose made during photosynthesis is crucial for the absorption of mineral ions by the roots as it provides the necessary energy and contributes to the osmotic balance required for this process.
