Theodor Schwann
Theodor Schwann (German pronunciation: [ˈteːodoːɐ̯ ˈʃvan]; 7 December 1810 – 11 January 1882) was a German physician and physiologist. His most significant contribution to biology is considered to be the extension of cell theory to animals.

Why cell is called structural and functional unit?

The cell is known as the structural and functional unit of life because all living beings are formed of cells. Cells are very important for performing various life processes which are required for sustaining life on earth. Moreover, cells give form and structure, process nutrients and make it into usable energy.

Why are lysosomes known as?

Answer: Lysosomes are sphere-shaped sacs filled with hydrolytic enzymes that have the capability to break down many types of biomolecules. Lysosomes are known as suicide bags of the cell because they contain lytic enzymes capable of digesting cells and unwanted materials.
