Do a nucleus have a nuclear envelope?

Answer 1

The plasma membrane, which is the membrane surrounding the cell, is a single phospholipid bilayer. Embedded in it are proteins and other compounds, such as cholesterol.

The nuclear envelope is double. This means that there are two phospholipid bilayers,with embedded proteins. In places the membranes connect, leaving a pore. This pore is important for permitting large molecules in and out of the nucleus, such as messenger RNA (mRNA) leaving the nucleus, and proteins synthesized in the cytoplasm entering for assembly into ribosomal subunits. Each pore is surrounded by proteins forming a nuclear pore complex.

The outer membrane of the nuclear envelope is continuous with the rough endoplasmic reticulum.

Answer 2

Yes, a nucleus does have a nuclear envelope. The nuclear envelope consists of two membranes and encloses the nucleus, separating its contents from the cytoplasm of the cell.

Answer 3

NUCLEOplasmis the space in the nucleus, a bit like the cytoplasm of the nucleus.

and the CYTOplasm is the space in the cell excluding the membrane.

Answer 4

The nuclear envelope is a membrane that envelops the whole nucleus, while nucleoplasm is liquid inside the nucleus. Outside of the nucleus, the liquid inside the cell is called cytoplasm.

Answer 5

The nuclear envelope is the double membrane that surrounds the nucleus. The cell membrane is the membrane that surrounds the cell itself.

Answer 6

Yes, they are the same Entity.

Answer 7

Yes. Also called the nuclear membrane.
