The question is not very clear.
Each cell is surrounded by a cell membrane. This cell membrane acts as a protective cover.
The cell membrane allows only small molecules (water) to enter and exit the cell. It does not allow larger molecules to enter.

How carbon dioxide water and sodium ions are transported across the cell membrane by both passive and active transport?
Carbon dioxide cannot be transported across the membrane by passive transport. However, water and sodium ions can be transported using passive transport.
Does active transport get substances across a cell membrane?
Transport proteins
What facilities passive transport across a cell membrane?
concentration gradient.
A type of passive transport across a cell membrane that requires special carriers is?
Active transport
Which part allows or prevents substances to go into and out of the cell?
The cell membrane acts as the barrier and transport proteins present in the membrane, such as globular proteins, transport molecules across cell membranes.
What is the transport of water across the cell membrane called?
Movement of water across a membrane is called OSMOSIS.
Movement of water across a cell membrane?
they pass through channels in the cell membrane
When do cells exchange materials across the cell?
A bilayer of phospholipids regulates cell traffic. There are five methods of transport across the membrane; diffusion, facilitated diffusion, active transport, co transport and endocytosis/exocytosis.
How carbon dioxide water and sodium ions are transported across the cell membrane by both passive and active transport?
Carbon dioxide cannot be transported across the membrane by passive transport. However, water and sodium ions can be transported using passive transport.
Is enewrgy required for the movement of water molecules across the cell membrane?
No. Osmosis is a form of passive transport.
How does the cell transport materials across the cell membrane?
a cell transports things across the cell membrane from areas of high concentration to ares of low concentration
The transport of a substance across the cell membrane against its concentration gradient is called what?
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
What are the types of membrane transport across the cell membrane require a protein carrier?
The brain
Does active transport get substances across a cell membrane?
Transport proteins
The diagram represents movement of a large molecule across a membrane?
It depends on what is moving across the membrane. Some molecules use transport proteins and the cell would need those embedded in the membrane. Water doesn't need them and it freely moves in and out.
What process occurs across the cell membrane?
the electron transport chain.
How does the Transport of molecules across the cell membrane take place?
osmosis
