How do you large molecules and ions pass through the cell membrane?

Recently had a homework on the cell membrane, i do know that larger molecules that cant fit through the polar heads into the cell (like gases can...and small molecules?!) can get through only if they qualify the shape fitting of the channel protein- the one that reaches all the way from the outside to the inside of the membrane.
hope this helps

How water molucleus move through the cell membrane doing out mosis?
During osmosis, water molecules move through the cell membrane by passing through microscopic openings in the membrane. The openings are large enough for the water molecules to pass through.
How do large polar molecules enter the cell?
The polar molecules goes through facillated diffusion. The molecules goes through the channel or membrane protein which then goes inside the cell.
What structures allow large important molecules to pass through the cell membrane?
A cell membrane is in every plant and animal and it lets in water, nutrients, and food to the cell. The membrane MUST be permeable because then it wouldn't of let the in water, nutrients, and food into the cell. If the membrane was stiff, the molecules of water, nutrients, and food would not be able to fit into the cell.
Molecules can pass through the cell membrane of the human cell?
The molecules that can pass through the cell membrane of the human cell include water. Other molecules include fat soluble vitamins.
Which organelle has a semi permeable membrane and separates the cell from it's environment?
The cell membrane (or plasma membrane) shows semi-permeability. In short some substances, such as gases and small electrically-neutral molecules CAN pass, while others like glucose and other large polar molecules CANNOT pass. Although glucose and other large polar molecules cannot pass through the semi-permeable cell membrane, they may enter through the interior of transport proteins.
Why do sugar molecules not diffuse through a plant cell membrane?
The membrane is semi-permeable. Sugar molecules are too large to diffuse through.
What is the process by which large molecules enter a cell through pouches in the membrane?
Phagocytosis

How do most molecules cross the cell membrane?
Diffusion or if the molecules are too large they go through the transport proteins.
Do substances enter any plant or animal cell by passing through a cell membrane?
Molecules can not pass through the cell membrane, because endocytosis is important for those large molecules that can not pass through the cell membrane!!
Why do passenger molecules need to be helped by the carrier protein?
Some molecules can't go through the cell membrane.
Molecules can pass through the cell membrane of the human cell?
The molecules that can pass through the cell membrane of the human cell include water. Other molecules include fat soluble vitamins.
How do large molecules get into the cell if they cannot fit via diffusion?
Through specialized carrier proteins in the cell membrane.
Large molecules are surrounded by the cell membrane and enter the cell?
A large molecule that can not enter the cell through myosis enters the cell through by endocytosis. Endocytosis is an example of active transport.
