The vacuole is a plant’s treasure chest. This cell, or vacuole, is at-
tached to the cell by a thin membrane and filled with a watery mixture.
This fluid is generally mildly acidic and consists of dissolved atmospher-
ic gasses; organic acids, sugars; pigments; oils that constitute the source of
perfumes and aromatic fragrances, glycosides that are used in medicines;
alkaloids known for their toxic properties; crystals; mineral acid salts; tan-
nins (mainly seen in the tea leaf)’ flavones which give flowers and fruits
their blue, purple, yellow and violet hues; and much else besides. All
these substances wait inside a vacuole too small to be seen with the naked
eye, which can be seen only under an electron microscope, for when they
can be of service to come. When the vacuole is full, it puts pressure on the
cell wall, and enables the plant as a whole to stand upright by pushing the
cytoplasm towards the cell walls.
Grass-like plants, which lack thick cell walls and any mechanical
support such as a woody stem, use this internal pressure in order to re-
main upright; and the plants wilt if they are unable to do this. At the same
time, the vacuole regulates the cell’s angle of incline towards the light and
the degree of moisture necessary for various reactions. 38
