Nutritients and water is the correct answer because roots and stems can absorve nutrients and water

Roots and stems carry:

Introduction:
Roots and stems are important parts of a plant that have specific functions. They play a crucial role in the transportation of essential substances within a plant. While both roots and stems serve different purposes, they work together to ensure the survival and growth of the plant.

1. Nutrients:
One of the main functions of roots and stems is to carry nutrients throughout the plant. Roots absorb nutrients from the soil, such as minerals and ions, and transport them to other parts of the plant. These nutrients are essential for various metabolic processes and growth. The stem acts as a conduit, providing a pathway for the transportation of these nutrients to the different parts of the plant, including the leaves, flowers, and fruits.

2. Water:
Roots are responsible for absorbing water from the soil through their root hairs. They have a specialized structure that allows them to take in water and minerals efficiently. Once the roots absorb water, it travels up through the stem to the rest of the plant. The stem acts as a pipeline, carrying the water to the leaves, where it is used for photosynthesis and other vital processes.

3. Translocation of sugars:
Another important function of roots and stems is the translocation of sugars. During photosynthesis, plants produce glucose, which is converted into sucrose for transport. The sugars are transported from the leaves, where they are synthesized, to other parts of the plant for energy storage or growth. The stem plays a vital role in this process by acting as a transportation system, allowing the sugars to move from the leaves to areas such as roots, fruits, or flowers.

Conclusion:
Roots and stems carry essential substances such as nutrients and water throughout the plant. They ensure that the plant receives the necessary resources for its growth and survival. While roots are responsible for absorbing nutrients and water from the soil, stems act as conduits, providing pathways for the transportation of these substances to different parts of the plant. Together, they play a crucial role in maintaining the overall health and functioning of a plant.
