Question

The nucleus is separated from surrounding cytoplasm by a nuclear membrane, which is:

• A. Single layered with pores
• B. Single layered without pores
• C. Double layered with pores
• D. Double layered without pores

Answer 1

Answer: (C)

Double layered with pores

Surrounding every nucleus is a double-layered membrane called the nuclear membrane or nuclear envelope. This membrane separates the nucleoplasm from the cytoplasm.

The nuclear membrane consists of two lipid bilayers - the inner nuclear membrane, and the outer nuclear membrane. It also has many small holes called nuclear pores that allow materials to move in and out of the nucleus.

So, the answer is 'C'.
