What else can I help you with?
What structure in a cell is composed mostly of a Phospholipid bilayer?
Most structures consist of a phospholipid bi-layer although that term is mostly associated with the cell wall in my experience. other structures such as the rough and smooth Endoplasmic Reticulum also use phospholipid bi-layers to partian themselves from the rest of the cell.
Is a cell membrane permeable impermeable or partially permeable?
Plasma membranes are selectively permeable.
Plasma membranes are a feature of?
Like all other cellular membranes, the plasma membrane consists of both lipids and proteins
What is selective ability?
Having selective ability means a person is very good at something and not that good at other things. Plasma membrane in our cells have selective ability.Synthetic membranes with selective ability have also been engineered.
What is the outer layer of a cell?
The outer layer of a cell is the cell membrane or plasma membrane
What is the system of membranes and tubes connecting nuclear membrane and plasma membrane?
Endoplasmic Reticulum
What are the differences between the plasma membrane and other membranes?
plasma membrane and other membranes are the same
Do prokaryotes have a nuclear membrane?
No. Prokaryotic cells do not have nuclear membrane, nor any membrane-bound organelle.
How many membranes are around the plasma membrane?
The plasma membrane is a bi-layer, so two.
Why is the nuclear membrane twice as thick as the plasma membrane?
The nuclear membrane is double-layered to provide additional protection and support for the delicate genetic material within the nucleus. This extra thickness helps to regulate the movement of molecules in and out of the nucleus, ensuring proper functioning of the cell.
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.
Plasma membranes consist of what kind of membrane?
A phospholipid bilayer.
What is the membrane that separates the content of the cell from the surrounding environment?
The membrane that separates the content of the cell from the surrounding environment is called the cell membrane or plasma membrane. It is a selectively permeable barrier that regulates the passage of substances in and out of the cell.
What is the difference between cell surface membrane and plasma membrane?
The diffrence is that the cell membrane is just a barrier between the exterior enviroment and the interior of the cell, while the cell surface membrane exerts control over what enters/leaves the cell! :)
When vesicles from the Golgi apparatus deliver their contents to the exterior of the cell they add their membranes to the plasma membrane. The plasma membrane does not increase in size because?
The membrane is continually being lost from the plasma membrane by endocytosis

What does the plasma membrane separate?
The nuclear membrane separates the content of the cytoplasm from those of the nucleoplasm. It also regulates the exchange of materials between the cytoplasm and nucleoplasm. The inner membrane of the nuclear membranes is involved in protein synthesis.
