What else can I help you with?
These form the cell membrane by lining up tails-to-tails in a double row?
Phospholipids form the cell membrane by aligning their hydrophobic tails in a double layer known as the lipid bilayer. The hydrophilic phosphate heads face outward towards the aqueous environment inside and outside the cell. This structure provides a selectively permeable barrier that regulates the movement of substances in and out of the cell.
Which organelle makes the phospholipids that compose the cells plasma membrane?
The cellular membrane is the organelle that makes the phospholipids that compose the cells plasma membrane. This is made as a collection of proteins and lipids.
Which organelle is covered by a double layer of plasma membranes?
The organelle covered by a double layer of plasma membranes is the mitochondria.
The cell membrane is made of a double layer of?
The cell membrane is semi-permeable controlling the movement of substances in and out of the cell. It contains a phospholipid bilayer consisting of hydrophobic tails and hydrophilic heads. Also contained in the cell membrane are transport proteins.
What organelle involved the processes of osmosis an diffusion?
Osmosis and diffusion take place across the plasma membrane, the outer "wall" of the cell. It is considered to be an organelle because it carries out a variety of functions. The cell membrane or plasma membrane is made up of a double layes of phosphorous and lipid molecules, known as the 'phospholipid bilayer'.

The cellular membrane is the organelle that makes the phospholipids that compose the cells plasma membrane. This is made as a collection of proteins and lipids.
The lipid bilayer is made up of a triple layer of phospholipids?
The lipid bilayer is actually composed of two layers of phospholipid molecules arranged in a double layer, not a triple layer. This structure provides the foundation for cell membranes, with the hydrophobic tails of the phospholipids facing inward and the hydrophilic heads facing outward.
What type of cells have membrane?
The cell's membrane is "selectively permeable" because the cell allows some materials to enter or leave.I'm in grade eight. This is what my Science textbook says:"Because the cell membrane allows certain substances to enter or leave, but not others, it is said to be selectively permeable."
Cell Membranes are contructed mainly of?
Cell membranes are primarily composed of lipids (such as phospholipids and cholesterol) and proteins. These components work together to form a flexible yet selectively permeable barrier that surrounds the cell and regulates the movement of substances in and out of the cell.
What statement best describes the role of the cell membrane?
The cell membrane controls what goes in an out of the cell.
A double layer of these molecules makes up the plasma membrane?
A double layer of phospholipids makes up the plasma membrane.
Through what parts of the nucleus do materials enter and leave?
Nucleus is enclosed in double walled nuclear membrane. Nuclear membrane at certain distance have pores in them which are called nuclear pores. Nuclear pores are very selectively permeable.
How is the structure of cell membranes influenced by the reaction of phospholipids to water?
A phospholipid is placed in water, it spontaneously folds upon itself to create a double layer. This reaction is also the foundation for fluid mosaic model of membrane structure. The internal membranes compartmentalize reactions to stop interference.
What is the plasma membrane made up of?
A double layer of phospholipids
Which organelle is covered by a double layer of plasma membranes?
The organelle covered by a double layer of plasma membranes is the mitochondria.
The cell membrane is made of a double layer of?
The cell membrane is semi-permeable controlling the movement of substances in and out of the cell. It contains a phospholipid bilayer consisting of hydrophobic tails and hydrophilic heads. Also contained in the cell membrane are transport proteins.
