When a cell takes in larger particles through a cell membrane?

When a cell needs to take in a particle larger than the membrane channels can passage, it will invaginate the cell membrane around the particle(s) and pinch off part of the membrane containing the particles inside the cell membrane. This is called phagocytosis (when the particles are primarily solid) or pinocytosis (when the particles are primarily liquid).


What is the difference between endocytosis and exocytosis?

Endocytosis takes material into the cell by infolding of the cell membrane. Exocytosis releases large amounts of material. Endocytosis: the process in which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell Excocytosis: the process in which a cell releases a particle by enclosing the particle in a vesicle that then moves to the cell surface and fuses with the cell membrane Endocytis is a process in the cell that happens when a cell is taking in a substance(Nutrients, Medicine, etc.) for uses inside the cell, Exocytosis is when the cell is getting rid of the waste


What is a small sac that forms part of a cell membrane?

A vesicle forms as a small sac from the cell's membrane.


When a cell membrane surrounds a particle encloses it into a vesicle and brings the particle into the cell this is called?

The process is called phagocytosis, which means "cell eating".


What is cell membrane permeability?

It is the ability of the membrane to allow ions and/or particles to cross.

Can small hydrophobic molecules cross the cell membrane?

Yes, small hydrophobic molecules can cross the cell membrane.


Can small polar molecules cross the cell membrane?

Yes, small polar molecules can cross the cell membrane through a process called passive diffusion.


What structure allow small particles to cross cell membrane?

Osmosis.


What kind of particle would move through a cell membrane the easiest- small or large-polar or nonpolar?

Small and nonpolar.


Which substances are able to cross the membrane, and what determines their ability to do so?

Certain substances, such as small molecules and ions, are able to cross the cell membrane. The ability of a substance to cross the membrane is determined by its size, charge, and solubility in the lipid bilayer of the membrane.


When a vesicle fuses with the cell membrane to get rid of a particle what happens?

a vesicle does not fuse with the cell membrane. The cell membrane goes through endo- or exocytosis to absorb or eject a substance. In this case, exocytosis occurs, so the cell membrane engulfs the particle, pumps it through the membrane with the help of transport proteins, and then the vesicle breaks off and is gone.


What is the protein binds to Particle and uses energy to move through the cell membrane?

protein binds to a particle and uses energy to move through the cell membrane


Define the step of endocytosis?

the process by which a cell uses energy to surround a particle and enclose the particle in a vesicle to bring the particle into the cell is called endocytosis: the cell comes into contact with particle the cell membrane begins to wrap around the particle then the particle is bought into the cell


Why can small hydrophobic molecules cross the membrane?

Small hydrophobic molecules can cross the cell membrane easily because the membrane is made up of a lipid bilayer that repels water but allows non-polar molecules, like hydrophobic ones, to pass through.


How does a cell perform?

A cell performs pinocytosis when it needs a fluid that's outside of the cell. It does this by taking in the fluid particle in through the cell membrane. It wraps the particle in a layer of the membrane. See the related link for an example.


Can nonpolar molecules cross the cell membrane?

Yes, nonpolar molecules can cross the cell membrane through simple diffusion.
