What is the structure that surrounds every cell?
The thin structure that surrounds the cytoplasm of a cell is called as cell membrane. This is present in most plant, animal and fungi cells. It is a selectively permeable structure and allows the flow of ions and particles from the inside of the cell to the outside and vice-versa. However plant cells, in addition to the cell membrane also have the cell wall outside the cell membrane. This provides mechanical rigidity to the cell and prevents the flow of larger particles.
Compared to the inside of the resting plasma membrane the outside surface of the membrane is?
The outside is slightly positive while the inside is slightly negative.
What is the layers on the outside of a cell membrane called?
The layer outside the cell membrane is the cell wall.
What is located outside of the nucleus membrane and is the site of many chemical reactions?
Cell Membrane
This type of membrane lines a body cavity that does NOT open directly to the outside?
Serous membraneA serous membrane also called the serosa is the type of membrane that lines cavities that do not open to the outside of the body.
When a seccretory vesile fuss with the plasma membraNE expelling its contents outside the cell?
This is called exocytosis.
How does the cell engulf liquid of small particles of matter?
Phagocytosis (cell eating) - form of endocytosis(folding in of cell membrane to trap material from the outside) ; cell membrane engulfs solid particles by wrapping around itPinocytosis (cell drinking) - form of endocytosis; cell engulfs liquids by sucking it in
What is the significance of the respiratory membrane?
A Membrane is responsible for all the movements of particles inside or outside the cell.
If there is more solute inside a membrane than outside solute particles will move across the membrane to the?
Concentration Gradient
Why is plasma membrane flexible?
Because it is a semi permeable membrane IE. it only allows selective particles to go inside it and outside it.

What is the thin structure surrounding an animal cell?
The thin structure that surrounds the cytoplasm of a cheek cell is called as cell membrane. This is present in most plant, animal and fungi cells. It is a selectively permeable structure and allows the flow of ions and particles from the inside of the cell to the outside and vice-versa.
What surrounds a plant cell and protects it?

What structure in a cell membrane repels charged particles?
The structure in a cell membrane that repels charged particles is the lipid bilayer. The lipid bilayer is composed of phospholipids, which have hydrophilic (water-loving) heads and hydrophobic (water-repelling) tails. This arrangement prevents charged particles from easily crossing the membrane.

Why is energy needed to move the particles across the plasma membrane?
Energy is only necessary for diffusion if the particles are being moved across the membrane against the gradient. ATP is necessary for this active transport as particles are moved from low concentrations to higher concentrations across the membrane. This is because passive transport, which does not use energy, only works to move particles down their concentration gradient. Ex. Such active transport is used in neuron cells to have a different charge inside and outside of the cell so that it can relay electric signals.
What functions to membrane proteins have?
The plasma membrane proteins have many functions. They pass on information through the membrane, they give the cell structural support and recognize different particles within the cell, and they are also transporters.
