What are mordern and old cell theory?

Answer 1

The generally accepted parts of modern cell theory include: All known living things are made up of one or more cells. All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms.
All living things or organisms are made of cells. New cells are created by old cells dividing into two. ... In 1839, Schwann and Schleiden suggested that cells were the basic unit of life. Their theory accepted the first two tenets of modern cell theory (see next section, below).

Answer 2

Heya dear......

The old cell theory states that:-

• All cells arise from pre-existing cells.
• Cells are the structural and functional unit of life.
• All organisms are made up of one or more than one cell.

The modern cell theory states that:-

• The cell contains hereditary information DNA which is passed on from cell to cell during cell division.
• All cells are basically the same in chemical composition and metabolic activities.
• All basic chemical and physiological functions are carried out inside the cells (digestion, movement etc).
• A cells activity depends on the activities of sub cellular structures within the cell (organelles, plasma membrane etc).
