Question

Which of the following is a function of the cell membrane of a cell? A. The production of energy from food molecules using cellular respiration. B. The production of genetic material through DNA transcription. C. The transport of molecules into and out of the cell through osmosis and diffusion. D. The transport of genetic material within the cytoplasm of the cell.

Answer 1

The answer is C. If you want a good experiment on this place an egg in a glass of vinegar for 6 hours, remove and place into corn syrup for 6 hours, and finally remove and place into water for 6 hours. you’ll get a really good example of osmosis in different stages.

Answer 2

C. The transport of molecules into and out of the cell through osmosis and diffusion.

Step-by-step explanation:

All cells have a structure called a plasma membrane or plasmalema, which acts as a barrier to prevent both the exit of cell content into the medium and the flow of any particle into the cell. The plasma membrane's main function is to transport molecules into and out of the cell through osmosis and diffusion in relation to the concentrations of salts and water inside and outside the cells. This characteristic therefore shows an important ability to select the structure, which can vary from 7 to 10 nm in thickness.
