water對animal cell 同 plant cells 有咩錦重要?!

Both animal cells and plant cell contain cytoplasm(細胞質).
The cytoplasm is a very important for a cell.
It contains organelles(細胞器) such as mitochondria and vacuoles.
Many cellulas chemical reactions take place here.

AND IT IS MAINLY MADE UP OF WATER.

If water is not present in the cell, the condition of the cytoplasm become unsteadable and thus doesn't function well.
As a result, the cell may die.
