• C. Water's ability to transport nutrients and waste in plants through capillary action
• D. Water's ability to dissolve a wide range of substances

Answer: (C)

Verified step by step guidance

1. Understand the properties of water: Water has cohesive properties, meaning water molecules are attracted to each other, and adhesive properties, meaning water molecules are attracted to other substances.
2. Recognize the role of cohesion and adhesion in biological systems: These properties are crucial for processes like capillary action, which is the movement of water within narrow spaces against gravity.
3. Identify capillary action in plants: In plants, capillary action allows water to move from the roots to the leaves through tiny tubes called xylem. This process is essential for transporting nutrients and waste.
4. Connect the properties to the function: The cohesive property of water helps maintain a continuous column of water molecules, while the adhesive property allows water to stick to the walls of the xylem, facilitating upward movement.
5. Conclude the importance: The cohesive and adhesive properties of water enable the transport of nutrients and waste in plants, which is vital for plant survival and, consequently, for life on Earth.
