The Vacuole helps plants stay up right because since the vacuole absorbs water, waste, and nutrients the pressure builds inside of it so then it propels the plant to stay upright. When the vacuole lacks water the plant wilts and becomes limp. [The Vacuole occupies 30-90% of the cell's volume]
The stem holds the plant upright and contains specialized cells that can elongate or shrink to adjust the plant's position towards the sun, a process known as phototropism.
The cell wall is the structure in a plant cell that gives it stiffness and support. Made of cellulose, the cell wall helps maintain the plant's shape and structure, allowing it to stand upright. It is an important feature that distinguishes plant cells from animal cells.
A meat used to hold a plant upright is a "steak." This term can refer to either a cut of meat or a wooden or metal rod used for support in gardening.
Plant supports are items that are used to help the plant or flower stay upright and not break under its own weight or from heavy winds. There are metal, plastic and wooden supports.
The leaves are full of oxygen that makes the kelp plant want to float to the top nod the water
For structure (to keep the plant upright), and it contains the phloem and xylem, which transports all the essential things like water, glucose and nutrients around the plant.
Vacuoles maintain the cell turgidity to keep the plants upright.
Roots
You can use a small thin wooden stick like the ones we use at barbeciou.Gently tie the plant on the stick(you will have afcourse to place a part of the stick inside the deart)

A great white dorsal fin does always stay upright in the water. The fin is what helps the shark swim.
The plant is referred to as "persistent."
