Final answer:
Osmosis is important in the structural support systems of plants as it helps in the absorption, retention, and flow of water and nutrients throughout the plant.
Step-by-step explanation:
Osmosis is essential to the structural support networks of plants, especially for turgor pressure maintenance. The pressure that the contents of the cell apply to the cell wall as a result of water entering the central vacuole through osmosis is known as turgor pressure.
Osmosis causes plant cells to absorb water, which causes the vacuole to expand and press on the cell wall. Because of the structural support provided by this pressure, the cells remain turgid and do not wilt. Turgor pressure also has a role in the stiffness of non-woody plant components like leaves and stems.
Plant cells that do not receive enough water uptake and turgor pressure might become floppy, which can cause wilting and jeopardise the plant's structural integrity. Thus, osmosis is essential to preserving the general structural integrity and shape of plants.
