1. what do you mean by "omnis cellulae a cellula"?

2. give me cell theory in detail?

"omnis cellula-e cellula" means that new cells arise from pre-existing cells.

Key points of the modern cell theory are:

All known living things are made up of one or more cells.

All cells arise from pre-existing cells by division.

The cell is the fundamental unit of structure and function in all living organisms.

The activity of an organism depends on the total activity of independent cells.

Energy flow occurs within cells.
