Prokaryotes and Eukaryotes Prokaryotic cells, which are primarily bacteria, consist of a single compartment containing DNA, RNA, proteins, and small molecules encapsulated by a plasma membrane, which is enclosed by a cell wall Eukaryotic cells, including fungus, plant cells, and animal cells, have a nucleus containing DNA and enclosed by a plasma membrane. Additionally, the cytoplasm contains many organelles also enclosed by a plasma membrane YOU CARRY OATS

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
