Answer:
Biogenesis = <u>Life from life</u> : Spontaneous Generation = <u>Life from non-living things</u>
Explanation:
As an accurate statement of the difference between spontaneous generation and biogenesis:
Spontaneous generation that sometimes refers to "abiogenesis" is an idea that life comes from non-living things/components. Whereas biogenesis is a contemporary concept that life can only arise from another living thing. 
Cell division, a baby of mice born from adult males and females, etc. are some examples of biogenesis. In contrast, there is no example of spontaneous generation. It remains a theoretical concept.
