Explanation:

First Question: How does water facilitate nutrient transport in plants?

• Option a: Water doesn't break down ionic compounds for nutrient transport in plants. Ionic compounds dissolve in water.
• Option b: Water enables capillary action (adhesion and cohesion), not block it. Capillary action helps in nutrient transport.
• Option c: Water is polar and dissolves polar substances, not nonpolar.
• Option d: Water's cohesion (attraction between water molecules) and adhesion (attraction to plant cell walls) allow capillary action, which helps in pulling water (and dissolved nutrients) up the plant. So this is correct.

• Option a: Nonpolar bonding is not a metabolic process that breaks down glucose.
• Option b: Photosynthesis produces glucose, it doesn't break it down for energy.
• Option c: Cellular respiration is the process where glucose is broken down (in the presence of water in some steps like glycolysis) to release energy (ATP).
• Option d: Surface tension is a property of water, not a metabolic process.

• Option a: Nonpolar substances don't act as catalysts for biochemical reactions.
• Option b: Polarity is a property of molecules (like water), not a catalyst.
• Option c: Enzymes are biological catalysts (proteins, sometimes RNA) that speed up biochemical reactions, and most biochemical reactions in cells (water - based environments) are facilitated by enzymes.
• Option d: Ionic compounds are substances that can dissolve in water, but they don't act as biological catalysts.

Answer:

d. Through cohesion and adhesion properties
