particles that are small and hydrophobic and semipermeable.
hydrophobic ions those that are soluble in lipids-- can easily pass through the membrane. In addition, small molecules like O2can sneak between the phospholipids of the membrane. On the other hand, hydrophilic molecules (like water and glucose) and ions (such as sodium ions and hydrogen ions) cannot pass directly through the phospholipids of the plasma membrane.
What else can I help you with?
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
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".
How do small particle cross a cell membrane?
Its either roadways and other stuff....
When a cell uses energy to transport a particle through the cell membrane to an of higher concentration the cell is using?
Active transport
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
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.

The process is called phagocytosis, which means "cell eating".
What kind of molecules can easily pass through a cell membrane?
Small, Non-polar molecules. If the molecule is polar, it sticks to both sides of the membrane, and has to go through selective routes. The easiest to get through is the Non-polar (oxygen and carbon).
What type of molecules can easily go through your cell membrane or are permeable to the cell membrane?
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
What is the process obtain by wrapping the cell membrane around the food particle?
Phagocytosis
How do small particle cross a cell membrane?
Its either roadways and other stuff....
What are two way in which a particle that is too large to fit through the cell membrane can enter the cell?
Particles to large to pass through the cell membrane can ebter by pinocytosis (cell membrane extends to surround a liquid and forms a new vacuole) or phagocytosis (the cytoplasm extends and surrounds the particle to be ingested)
