               2.All living organisms have cells

               3.vacuoles

Explanation:

1.Cells are called the structural and functional unit of life because all the living organisms are made up of cells and also all the functions taking place inside the body of organisms are performed by cells. Cells provide specific conditions, for the occurrence of the metabolic reactions. These have specialized enzymes, which catalyze the biochemical reaction and regulates the functions of the body.

2.The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. Rudolf Virchow later made important contributions to this theory.

3.A plant cell's vacuole can make up 90% of the cell's volume. The large central vacuole essentially stores water. In animal cells, vacuoles are much smaller.
