What is this method of molecular transport is called?
Molecular Transport (in cells) is the movement of materials across a cell membrane. The two kinds of Molecular Transport used in organisms are Active Transport and Passive Transport. Active Transport- materials move across the plasma membrane with the use of energy (like Adenosine Triphosphate) Passive Transport- materials move accross the plasma membrane without the use of energy
The movement of materials through a cell membrane without using the cells energy?
It's called passive transport for a cell's membrane. (I checked with my science teacher)
What is vesicular transport out of the cell?
Vesicular transport is an active process in which materials move into or out of the cell enclosed as vesicles. Vesicles are bubble-like structures surrounded by a membrane. They can form at the cell membrane or can fuse with the membrane. Solid particles, droplets of fluid or many molecules at a time can be moved across the membrane in vesicles. Vesicular transport is also known as bulk transport because large quantities of materials can be transported in this way. Th ere are two basic types of vesicular transport-endocytosis and exocytosis.
What controls the materials going in and out of a cell?
The Cell Membrane Makes Sure that the materials going in and out of the cell are not harmful, such as a virus.
When materials enter the cell by passive or active transport these materials literally cross through the cell membrane can the same be said of materials that enter the cell by phagocytosis?
Yes, materials that enter the cell by phagocytosis also cross through the cell membrane, but in a different manner compared to passive or active transport. In phagocytosis, the cell membrane engulfs large particles or microorganisms, forming a vesicle that brings these materials into the cell. This process involves the membrane folding around the substance rather than allowing it to pass through like smaller molecules do in passive or active transport.
A twisted membrane with portions that breakoff to form vesicles that transport materials?
This process is called endocytosis, where the cell membrane invaginates to form vesicles that transport materials into the cell. These vesicles can then fuse with other organelles or transport materials to other parts of the cell.
What types of materials does osmosis transport?
Osmosis transports water molecules across a partially permeable membrane, such as a cell membrane. It does not transport other types of materials, like ions or larger molecules.
What is the process of moving materials across membrane with energy?
active transport
What controls movement of materials in and out of the cell?
The cell membrane regulates the movement of materials in and out of the cell through processes such as diffusion, osmosis, and active transport. Additionally, specific transport proteins embedded in the membrane facilitate the passage of certain molecules and ions.

Which transport mechanisms moves materials across a plasma membrane against an apparent concentration gradient?
active transport
What process require ATP energy to transport materials across a selectively premeable membrane into the cell?
active transport
Distinguish between active and passive transport?
Active Transport is the passage of materials across the membrane through the expenditure of energy. Passive Transport is the passage of materials across the membrane without the expenditure of energy. Bulk Transport is the type of active transport. Diffusion and Osmosis are type of passive transport.
What is the pumping of materials across a membrane against their concentration gradients?
Active Transport
What type of active transport brings materials into the cell?
Cell membrane pump
How does the cell membrane know when to transport water and materials into and out of the cell?
It doesn't! it just lets some materials that are useful for the cells into the membrane and others out, through diffusion.
Which type of transport is the coupled passage of two materials across a membrane?
Symport is the type of transport that involves the coupled passage of two materials across a membrane in the same direction. It relies on a concentration gradient to move both substances across the membrane simultaneously.
