NEET BIOLOGY

Detailed explanation-1: -All living 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 (metabolism and biochemistry) occurs within cells.

Detailed explanation-2: -The third part of the cell theory definition states that all cells come from preexisting cells. This means that cells don’t just appear out of thin air (known as “spontaneous generation”). New cells are always made from current cells.

Detailed explanation-3: -Cells arise from the pre-existing cells is the second postulate of cell theory. Rudolf Virchow proposed this.

Detailed explanation-4: -All living things are made up of cells. Cells are the smallest units (or most basic building blocks) of life, and all cells come from preexisting cells through the process of cell division. Life cannot be created in a laboratory.

Detailed explanation-5: -Concept 7 All cells arise from pre-existing cells. For centuries people accepted the “spontaneous generation” of life from inanimate matter. When this long-standing myth was finally dispelled in the mid-1800s, it became clear that all life must arise from pre-existing life-via a process of reproduction.
