Diffusion, facilitated diffusion, Osmosis and Active Transport.
Diffusion moves non-polar molecules across the cell membrane down a concentration gradient. Osmosis moves water across the cell membrane through a channel formed by aquaporins called a protein channel, down the water potential gradient. Active moves the non-polar molecules against the concentration gradient, in contrast to diffusion. Lastly, facilitated diffusion moves polar molecules across the cell membrane through creating protein channels in the cell membrane from specific proteins. ETC, glucose transporters bind to form a protein channel for glucose to diffuse through, after which the proteins disperse. That should be all, hope it was of help!

What keeps the cytoplasm inside and allows nutrients in and waste products out?
The cell membrane and cell wall keep the cytoplasm inside a cell and allows nutrients and waste products out, in fact, the cell membranes only allows what they want through, if the substance is alien to them, it will be refrained.
What in meant by the following statement about the cell membrane?
It is very selective about what it allows to pass through.
The cell uses energy to transport glucose through the cell membrane?
Glucose moves across the cell membrane through facilitated diffusion. This type of transport uses protein carriers to assist glucose molecules across the cell membrane from an area of high concentration to an area of low concentration.
What Controls what goes in and out of the cell?
The phosopholipid bilayer of the cell membrane controls what moves into and out of the cell based on receptors on the cell's surface.
What moves large amounts of material across the cell membrane?
Through fusion with the cell membrane, vesicles transport large molecules and material in a process called exocytosis.
Which material move through the cell in diffusion?
All the imports and exports of cell moves through plasma membrane by diffusion. Which includes proteins, water, nutrients and the products of the cell. The material in excess amount in or out of the call moves in or out of the by diffusion.
What is a structure that moves material through a cell?
it's the cell membrane
Why does water pass quickly through cell?
it moves through aquaporins in the membrane.
How can you use water osmosis cell and cell membrane in a sentence?
Water moves in and out of the cell through the cell membrane by the process of osmosis when there is a concentration gradient.
What is folded membrane that moves materials through the cell?
endoplasmic reticulum
Is movement of alcohol through cell membrane osmosis?
Alcohol moves across the cell membrane by means of osmosis.
Through what part of a cell do materials enter and waste products leave?
The cell membrane
How does oxygen moves into cells?
The cell membrane simply accepts it when it is delivered through the blood.
What cell controls what moves in and out of cell?
Cell membrane
What is meant by the statement the cell membrane is to be fluid?
The membrane moves sidewaysit moves sideways
Waste products in the cell accumulate and are eventually?
The eventually exit the cell through the cell membrane and come out in you r pee.
How do liquids go through cell membrane?
Fluid moves into the cell through a passive process known as diffusion. Osmosis is the special name given to the diffusion of water across the semi-permeable membrane of the cell.
