A few key differences:

DNA and RNA are abbreviations for deoxyribonucleic acid and ribonucleic acid respectively. This difference has to do with the fact that DNA contains a sugar called deoxyribose while RNA's sugar is simply ribose.
DNA has a double-helical structure while RNA is a single strand (resembling a single strand off a DNA's double helix). See the attached image for an illustration of this structure.
The bases of DNA are guanine, cytosine, adenine, and thymine. In RNA, by contrast, thymine is replaced by uracil.
Functionally, DNA is a kind of storage unit for genetic information. RNA uses this information to build proteins, copying it from the master copy contained in the DNA and converting it to a form the ribosomes can use.

How does the movement of materials across the cell membrane relate to an organism’s survival?

ioda

I believe it relates because as we know the cell membrane is permeable meaning that allows oxygen, carbohydrates, food to enter the cell but it doesn't allow the entrance of large molecules that harm the cells.

After all the movement around it, matters because for example without food the mitochondria won't be able to create the energy and then with that energy, the nucleus to use it to complete the main the activities of the cell.

Hopefully this what you meant when you asked the question. Have a nice day/evening
