Lignin, a major component of the vascular plant cell wall, provides mechanical support for plants to stand upright and enables xylems to withstand the negative pressure generated during water transport.

The two structures that provide strength and support for plants to stand upright are the cell wall and the vascular tissue, specifically xylem. The cell wall, composed mainly of cellulose, offers rigidity and structural integrity. Meanwhile, xylem transports water and minerals, creating internal pressure through turgor that helps maintain the plant's upright position. Together, these structures enable plants to support their weight and resist bending or collapsing.
A test tube can be held upright using a test tube rack, a test tube holder, or a clamp attached to a stand. These tools provide stability and prevent the test tube from tipping over during experiments.
Turgidity. The ability of plants, with their cell walls, to take in a abundance of water which makes the cell rigid from the water pressure. Thus, with all cells turgid, the plant is able to stand.
The leaves of a plant are upright in the morning due to a process called nyctinasty, which is a circadian rhythm response to light. During the night, the leaves droop to conserve water and reduce surface area exposed to potential frost. As the sun rises, the plant's cells actively pump water into the leaves, causing them to become turgid and stand upright, maximizing exposure to sunlight for photosynthesis. This movement is controlled by changes in turgor pressure within the plant cells, regulated by the plant hormone auxin.
to allow the plant to stand upright
Lignin, a major component of the vascular plant cell wall, provides mechanical support for plants to stand upright and enables xylems to withstand the negative pressure generated during water transport.
Those are likely cattails (Typha). Cattails are aquatic plants that are commonly found in wetlands and ponds. They have long, slender leaves and produce cylindrical brown seed heads that stand upright.
Creeper are those plants which can not stand upright they need support example watermelon plant,money plant etc \
Fluid pressure from freshwater helps plants stand upright through a process called turgor pressure. When plant cells absorb water, they become turgid and press against the cell wall, providing support and rigidity to the plant structure. This pressure helps plants maintain their shape and stand upright.

No. Trout do not stand upright.
cell wall and turgor pressure
One simple example is a tree, which can stand upright alone. Some plants, especially some garden plants, may need help to keep upright by using bamboo canes, etc.
