Question 47

Roots are specialized for the absorption of water and nutrients from the environment.

Roots serve as the primary structure in plants for absorbing water and essential minerals from the soil, facilitating growth and development.

A) Roots

Roots are specifically adapted to maximize water and nutrient uptake. They have a large surface area due to root hairs and can penetrate the soil to access moisture and nutrients, making them the most important structure for this function.

B) Leaves

While leaves play a crucial role in photosynthesis and gas exchange, they are not specialized for the absorption of water and nutrients. Instead, they primarily capture sunlight and facilitate the process of transpiration, which indirectly supports nutrient transport.

C) Flowers

Flowers are reproductive structures in plants and are not involved in the absorption of water and nutrients. Their main function is to facilitate reproduction through the production of seeds and fruits, making them unrelated to nutrient uptake.

D) Stems

Stems provide structural support and transport water and nutrients between the roots and leaves but do not specialize in the absorption of these resources. Their role is more about distribution rather than absorption.

Conclusion

Roots are definitively the structures specialized for the absorption of water and nutrients, as they are designed to interface directly with the soil environment. In contrast, leaves, flowers, and stems serve different functions within the plant, highlighting the unique role of roots in nutrient acquisition.
