What part of the plant is responsible for anchoring it in the soil and absorbing water and nutrients?

The roots of a plant play a crucial role in anchoring it securely in the soil, which provides stability and support, allowing the plant to grow upright. Additionally, roots are essential for water and nutrient uptake from the soil, which are vital for the plant's survival and overall health. They possess specialized structures that enhance their ability to absorb these resources effectively.

Leaves primarily focus on photosynthesis, stems provide support and transport nutrients and water between roots and leaves, while flowers are involved in reproduction. Thus, roots are distinctly responsible for anchoring the plant and facilitating the absorption of water and nutrients, making them the correct answer in this context.
