Cell membranes acts as a barrier for the large,charged and polar molecules due to their hydrophobic nature.

These molecules are transported with the help of membrane proteins such as carrier proteins across the plasma membrane by a process known as facilitated diffusion. These membrane proteins diffuse larger molecules across the cell membrane that cannot be transported by simple diffusion.

In this activity, you will distinguish the theories of spontaneous generation and biogenesis.
zhannawk [14.2K]

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.
