Detailed explanation-1: -The cell theory states that all living organisms are made up of structural and functional units called cells and new cells can arise only from preexisting cells. The spontaneous generation theory on the other hand, states that living organisms arise from nonliving matter.

Detailed explanation-2: -The theory of Biogenesis is based on the idea that life can only come from life, and it refers to any process by which a lifeform can give rise to another lifeform. It is an important theory of biology and molecular genetics, which postulates the production of new living organisms from preexisting life.

Detailed explanation-3: -Biogenesis means making new living things. More specifically, it is the theory that living things only come from other living things through reproduction. Abiogenesis, sometimes called spontaneous generation, means life coming from non-living things.

Detailed explanation-4: -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.

Detailed explanation-5: -Biogenesis means life comes from pre existing life, as in modern earth. Now life comes from pre-existing life only but life actually evolved from non living components abiogenetically.
