What is the function of stems?

Stems serve multiple critical functions for plants, primarily focusing on support and transport.

Key Functions of Stems

Here's a breakdown of the main roles stems play:

Transportation

• Water and Nutrients: Stems act as the main transportation routes, carrying water and essential nutrients absorbed by the roots upwards to the leaves.
• Sugar Transport: They also transport sugars produced during photosynthesis in the leaves to other parts of the plant for energy and growth. The reference material states: "The stem transports water and nutrients up from the roots all the way to the leaves, and the stem transports sugars from the leaves to the rest of the plant."

Support

• Structural Support: Stems provide the necessary support for the plant, holding up leaves, flowers, and fruits. This ensures that leaves receive adequate sunlight for photosynthesis.

Overall Role

Stems, therefore, are crucial for a plant's survival. They ensure that all parts of the plant receive the resources they need to function correctly, from water and nutrients to sugars, while also supporting the plant's structure. As the reference states, "Stems support leaves, flowers, and fruits."
