What else can I help you with?
What protects the nucleus by allowing only certain materials to pass in or out?
The nucleus has a membrane much like the membrane around the entire cell.
What organelle surrounds every cell?
The nucleus of a cell is surrounded by the nuclear envelope, which is the semipermeable membrane around the nucleus. The organelle that surrounds the nucleus is the cytoplasm.
What is the organism that has membrane around nucleus?
Eukaryotes are the organisms that have a membrane bound nucleus.
What is in the nucleus?
The nucleus contains the cell's genetic material, organized as chromosomes, which carry the instructions for cell growth, development, and reproduction. It also contains the nucleolus, responsible for producing ribosomes, and is surrounded by a nuclear membrane that controls the movement of materials in and out of the nucleus.
Does a cell have a brain?
Yes and no. Cells have something which is called a nucleus. The nucleus is kind of like the brain. It tells the cell what to do and when to divide or split. The nucleus is usually in the middle of a cell. It is surrounded by the nuclear membrane. Around the nuclear membrane is cytoplasm. Cytoplasm has smaller microbes inside which carry out the duties the nucleus(brain) has given them. The protecting the cytoplasm is the cell membrane which is the outer shell of the cell or the skin.
difference between nucleoid and nucleus?
A nucleoid is a region within a prokaryotic cell that contains the genetic material (DNA), which is not surrounded by a membrane. The nucleus, found in eukaryotic cells, is a membrane-bound organelle that houses the cell's genetic material and controls cellular activities. The main difference is that the nucleoid is not surrounded by a membrane, while the nucleus is enclosed by a double membrane.
Surrounded the nucleus of an atom?
Ok, I think you mean electons. The nucleus is made up of protons and neutrons, surrounded by electrons. An electron has a negative charge. It is so light, it has negligible mass. The atom Hydrogen has only one proton as its nucleus, surrounded by its one electron. Oxygen has, of the top of my head, 8? electrons. These electrons move in orbitals around the proton. Without going into complicated detail, that's all I can tell you I'm afraid.
What organelle controls what enters and leaves the nucleus?
nuclear ,membrane
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.
What is is the nucleus surrounded by?
The nucleus is surrounded by two types of cell membranes, the inner and outer nuclear membranes. The nucleus can also float around in the cytoplasm.
Where is the nuclear membrane found in a cell?
Around the nucleus
What type of cell doesn't have a membrane around their nucleus?
Prokaryotic cells do not have a nuclear membrane.
