2.14 Understand the importance in plants of turgid cells as a means of support

Plants need water to perform photosynthesis. Turgid cells are cells that are full of water. Due to the cell wall, it does not burst (unlike animal cells). The cytoplasm and cell membrane is pressed against the cell wall, making the cell look "inflated" (which, it technically is but it's not great to write that in an exam)

Because the cells are turgid, they press against each other, forming a firm structure, and so are a plant's means of support.
