Soil solution is very dilute $10^{-3}M$. It is in equilibrium with minerals adsorbed over colloidal particle.

Plants absorb water and mineral salts simultaneously through root hairs, not sequentially. The statement that plants absorb one thing at a time is incorrect because absorption of water and minerals occurs concurrently through the same root tissues. Mineral absorption does primarily occur through active transport methods.

Heavy metals like mercury (Hg2+) act as non-competitive or irreversible inhibitors by binding to the sulfhydryl groups of enzymes, thereby denaturing them or blocking their active sites.

Plants obtain minerals from the soil, which are derived from the weathering and breakdown of rocks. Therefore, all these sources contribute to the mineral content available to plants.

Mushrooms are often called 'vegetable meat' because they contain a significant amount of protein, making them a good plant-based protein source.

Phytochelatins are cysteine-rich peptides that bind to heavy metals, allowing plants to sequester and detoxify them within vacuoles.

A dirt's fruitfulness, which is a substantial property, is simpler to change than the dirt's physical properties. A natural issue, the dirt minerals present, and the seepage conditions all impact soil shading. 

Etiolation is a process in plants grown in partial or complete absence of light, characterized by long, weak stems and pale yellow leaves. It is a developmental response to light deprivation, not a symptom of mineral deficiency.
