* Stems: The main supporting structure of a plant, stems provide rigidity and hold up leaves, flowers, and branches. They also transport water and nutrients.
* Xylem: This is a specialized tissue within the stem that transports water and minerals from the roots to the rest of the plant. It provides structural support due to its rigid cell walls.
* Phloem: This tissue transports sugars produced by photosynthesis from leaves to other parts of the plant. While less rigid than xylem, it contributes to overall stem strength.
* Cell Walls: Plant cells have tough, rigid cell walls made of cellulose. These walls provide structural support to individual cells and help the plant maintain its shape.
* Root System: The roots anchor the plant to the ground and absorb water and nutrients. A strong root system provides stability and prevents the plant from being blown over by wind.
* Turgor Pressure: Water inside plant cells creates pressure against the cell walls, helping to keep the plant rigid and upright.
Different types of plants use these structures in different ways. For example, trees have thick woody stems and strong root systems to support their massive size. Vines rely on tendrils to climb and grow upright.
