What is necleur membrane?
The nuclear membrane is a double-layered membrane that surrounds the nucleus of a eukaryotic cell. It acts as a barrier to regulate the passage of molecules in and out of the nucleus, allowing for communication between the nucleus and the rest of the cell. The nuclear membrane also plays a role in protecting the DNA within the nucleus.
Cell membrane is to a cell as nuclear membrane is to?
Nucleus. Both cell membrane and nuclear membrane are protective barriers that separate and regulate the contents of the cell and nucleus, respectively. They control the movement of substances in and out of their respective compartments.
What are folded layers of the inner membrane in mitochondria called?
I think you are referring to the cristae. These are the folded parts of the inner membrane. The purpose is to increase surface area of the inner membrane against the matrix. The membrane is the site of the energy transfer in the mitochondria, so having more surface area is a plus.
What part of the cell is enclosed by it own membrane?
The nucleus is the part of the cell that is enclosed by its own membrane, known as the nuclear membrane or nuclear envelope. This membrane separates the nucleus from the cytoplasm of the cell and helps regulate the movement of molecules in and out of the nucleus.
What is the double bilayer membrane that contains the nucleus?
The nucleus is found inside a lipid bilayer membrane that is very similar to the membrane around the entire cell. It is called the nuclear membrane.
How is the innermost of these layers different from that of the nucleus?
The inner mitochondrial membrane is highly folded
What are the functions of the endoplasm?
The endoplasmic reticulum is a folded membrane what moves about the cell. It extends from the nucleus to the cell membrane. It is responsible for the production of the protein and lipid. Ribosomes also make proteins.
Are the nucleus and the mitochondrion surrounded by two layers of unit membrane?
Yes, both the nucleus and mitochondria are surrounded by two layers of unit membrane. The nucleus is surrounded by the nuclear envelope, made up of two lipid bilayers, while the mitochondria have an outer and inner mitochondrial membrane.
Why is the inner membrane folded?
Mitochondria
What does a nucleus membrane do?
a nucleus membrane protect any materials from it
Do archaebacteria have a cell membrane or a nucleus?
They have a cell membrane but no nucleus.
Where is the DNA stored in a cell?
In the Membrane bound nucleus
Do bacteria have a membrane-bound nucleus?
No, bacteria do not have a membrane-bound nucleus.
What organelle controls what enters and leaves the nucleus?
nuclear ,membrane
What organelles has single membrane?
Most of them. Lysosomes, endoplasmic reticulum, golgi apparatus, peroxisome, vacuoles all have single membranes. Nucleus has double membrane to make it less permeable, chloroplasts have membrane bound structures (thylakoid) inside its two membranes, and mitochondria have larger membrane that is folded within the outer membrane for added surface area.
Is the nucleus part of the nuclear membrane?
Yes. The nuclear membrane includes the nucleus. It allows movement into and out of the nucleus.
What sourronds the nucleus?
The nucleus membrane.
