∙ 13y agoThe plasma membrane is made of a phospholipid bilayer. The phospholipids kinda look like sperm, with a head and tail. The tails are hydrophobic and the heads are hydrophylic, so they arrange themselves in a circular shape with the heads on the outside and the tails on the inside. The heads touch the water on the inside and outside and the tails are in the middle.

Difference between plasma membrane and cell wall?
wikipedia " plasma membrane" the membrane is thin bi-lipid (two-fat) layer that blocks out water the cell wall is a rigid cube like structure that surrounds a plant cell and gives it rigidity jd
Compare and contrast the functions of a cell wall to the functions of a plasma membrane?
The differences between cell wall and cell membrane are:Cell wall is made of cellulose while plasma membrane is made of lipids & proteins.Cell wall is freely permeable but cell membrane is selectively permeable.Cell wall is dead but plasma membrane is living.Cell wall is rigid but plasma membrane is smooth, elastic and flexible.Cell wall is found only in plant cells but plasma membrane is found in all liviing cells.
What is selectively permeable?
The property of a membrane or other material that allows some substances to pass through it more easily than others.Selective permeability refers to the control that a cell membrane has in terms of what it allows to cross it. This gives the cell membrane the ability to choose which molecules enter or leave.
What gives water the ability to cross the hydrophobic region of a cell membrane when other small polar molecules and ions cannot?
Bc its fckn water
What gives the cell its shape and provides protection?
The cell wall or membrane is the one that shapes and protects the cell. It has the function of controlling what comes into and out of the cell.
Is the cytoskeleton in the plasma membrane?
No. It is attached to the plasma membrane though, which is important. The cytoskeleton gives cells shape and rigidity etc and so it is important for it to be attached to the plasma membrane. The cytoskeleton is composed of molecules that are located in the cytoplasm but that are attached to the plasma membrane via specific proteins. Hope that helps!
What is a fibrous protein that gives shape to an RBC plasma membrane?
spectrin

What are the functions of the plasma membrane in Eukaryotes?
Plasma membrane gives structure to the cell, serve as boundary. It allows the selective passage of molecules across the cell (semi permeable). Starts the signalling event from the receptors it posses on the membrane surface when there is a stimuli bind to it.

What molecules add support to plasma membrane?
The intrinsic properties of the hydrophilic/hydrophobic/hydrophilic double layer of the membrane gives it support, due to the hydrophobic effect.
Does the plasma membrane give strength to the cell?
It controls what enters and leaves a cell, it also gives it support and shape.
What is selectively permeable?
The property of a membrane or other material that allows some substances to pass through it more easily than others.Selective permeability refers to the control that a cell membrane has in terms of what it allows to cross it. This gives the cell membrane the ability to choose which molecules enter or leave.
What are the copmonents of the cell and what are there functions?
the main components of a cell are the nucleus the cytoplasm and the plasma membrane .the nucleus controls all life activities of the cell.the cytoplasm serves as a home for all the organelles and the plasma membrane also also called cell wall gives shape and support to the cell
What is a structure outside the plasma membrane and gives support to some cells?
This structure is called a cell wall and it is found in plant cells and bacteria cells.
Which part of the animal cell gives shape to the cell?
cell membrane The cells and organs surrounding it give the animal cell its shape. The membrane is totally flexible and confers no shape to the cell.
In science what gives a protective layer that gives the shape of a plant to the plant cells.One of your answers should be cell (plasma) membrane, nucleus, cytoplasm, vacuole, chloroplasts, cell wall, mitochondria, or ribosomes?
The cell wall.
