The nuclear envelope is a solid barrier that prevents the movement of molecules between the nucleus and the cytoplasm. A) True B) False

Understand the Problem

The question is asking whether the statement regarding the nuclear envelope being a solid barrier is true or false. It requires knowledge about the structure and functionality of the nuclear envelope in a cell.

More Information

The nuclear envelope is not a solid barrier; it contains nuclear pores that regulate the movement of molecules between the nucleus and the cytoplasm, thereby allowing specific molecules to pass through.

Tips

A common mistake is assuming the nuclear envelope completely blocks movement, but it's the nuclear pores that selectively allow materials to move between the nucleus and the cytoplasm.
