Step 1
D) Water and mineral ions
Answer
Root hair cells are specialized for the absorption of water and essential mineral ions from the soil. These cells increase the surface area for absorption and are primarily responsible for taking in nutrients necessary for plant growth. Without water and mineral ions, plants would struggle to survive as these substances are crucial for various physiological processes, including photosynthesis and nutrient transport.
