Hint: Life: Life is a biological concept which includes characters, state that separates a living thing from dead matter.
The word may refer to a living being.
Living beings consist of cells which are known as basic units of life.
Complete answer:
The idea of spontaneous generation is a theory that states that living organisms can originate from inanimate objects (dead matter or non living)
Examples of spontaneous generation were:
1. Dust creates fleas
2. Maggots arise from rotting meat
3. Bread or wheat left in a dark corner produces mice.
Many experiments were conducted to prove and disprove the theory.
In 1668, Redi introduced the first experiment challenging spontaneous generation theory.
In this experiment, he demonstrated that maggots arise from the eggs of flies instead of directly arising from rotting meat.
He did this experiment by taking several jars and placing raw meat inside of them.
Half of the jar is covered by gauze and half is left opened.
In 1745, Needham set out an experiment to prove this by boiling broth in a flask and then leaving it open to cool and sealing it.
In several days the broth was completely full with bacteria and mold. He declared that this proves the existence of spontaneous generation for microorganisms.
So, they concluded that the theory of spontaneous generation means origin of life from non-life.
So, the correct option is option A. Origin of life from non-life.
Note: Biogenesis means making new living things.
This theory states that living things only come from other living things or organisms through reproduction.
Abiogenesis is also called spontaneous generation which means life coming from non-living things.
