How many membrane layers cover the nucleus?
There isn't a specific number of membranes that a eukaryote has, mainly because it is unknown how many organelles are in a cell and how many cells are in an organism. A eukaryotic cell is surrounded by one plasma membrane, but most organelles within the membrane are also covered with membranes, sometimes two in case of mitochondria or chloroplast.
How many membranes does this organelle have?
The number of membranes an organelle has varies depending on the specific organelle. For example, mitochondria and chloroplasts each have two membranes, while the endoplasmic reticulum and Golgi apparatus have a single membrane. Nuclei also have a double membrane structure known as the nuclear envelope. If you specify a particular organelle, I can provide a more precise answer.
How many membranes enclose the contents of the chloroplast?
Two membranes enclose the contents of the chloroplast - the outer membrane and the inner membrane.
The cell membrane and the nuclear membrane are made of?
the cell membrane, also known as the plasm membrane, forms a boundary between a cell and the enviroment and is made of a double layer of phospholipids. A phospholipid is made of a charged phosphate group, a glycerol, and two fatty acid chains.
How many membranes are in the chloroplasts?
Nucleus is surrounded by a double membrane.
How many membranes are around the plasma membrane?
The plasma membrane is a bi-layer, so two.
What is the function of a nuclear membrane of a plant cell?
The nuclear envelope (NE) (also known as the perinuclear envelope, nuclear membrane, nucleolemma or karyotheca) is a double lipid bilayer that encloses the genetic material in eukaryotic cells. The nuclear envelope also serves as the physical barrier, separating the contents of the nucleus (DNA in particular) from the cytosol (cytoplasm). Many nuclear pores are inserted in the nuclear envelope, which facilitate and regulate the exchange of materials (proteins such as transcription factors, and RNA) between the nucleus and the cytoplasm.Each of the two membranes is composed of a lipid bilayer. The outer membrane is continuous with the rough endoplasmic reticulum while the inner nuclear membrane is the primary residence of several inner nuclear membrane proteins. The outer and inner nuclear membrane are fused at the site of nuclear pore complexes. The structure of the membrane also consists of ribosomes.
How many nuclear membranes must form when a single dividing cell reaches telophase?
If a cell divides into two cells, duruing telophase, then there must be one nuclear membrane per cell. Therefore the answer to your question should be 2.
How many membranes surround bacteria?
Only 1 membrane surrounds bacterias
How many layer of plasma membrane circulate the ribosomes?
They do not have membranes. They are naked organelles
How many nuclear membranes must form before telophase?
Two nuclear membranes must form before telophase, as the nuclear envelope reforms around the individual sets of chromatids within each daughter cell.
What is a double membrane which encloses the nucleus and contains many openings called pores?
nuclear membrane
