Does a cell membrane help substances pass from cytoplasm into the nucleus?

Answer 1

The cell membrane on an animal cell is the outermost layer and acts as a protection shield. It is selectively permeable meaning it only lets certain things into the cytoplasm of the cell. The nucleus does not have a cell membrane, it simply directs the cells activities. In a plant cell there is a cell wall on the outside of the cell membrane giving the cell support and protection, but the cell membrane still provides the same function as it does on the animal cell.

Answer 2

No, the cell membrane does not play a role in allowing substances to pass from the cytoplasm into the nucleus. Substances move between the cytoplasm and nucleus through nuclear pores in the nuclear envelope. These nuclear pores regulate the passage of molecules, including proteins and RNA, ensuring only specific molecules can enter or exit the nucleus.
