What is the name of the membrane that allows the movement of water and substances to move through the process of active transport and passive transport?
The name of the membrane that allows movement of water and substances through the process of active and passive transport is semipermeable membrane.
What is the movement of substances through a cell membrane without the use of cell energy?
passive transport
What is it called when the movement of materials through a cell membrane without using the cells energy?
Passive transport does not use energy to pass through a cell membrane. active transport uses energy to pass through a cell membrane.
What separates active transport from passive transport?
Active transport is when a cell needs to use energy in or to let substances pass in through or out or its cell membrane or cell wall. Passive transport requires to energy at all making substances like water easy to let pass through.
The movement of substances through a cell membrane without the use of cell energy?
Passive transport using osmosis and diffusion. Osmosis only applies to the movement of water down a concentration gradient across a selectively permeable membrane. DOH!!!
How does a cell membrane allow nutrients to get in?
The cell membrane is semi-permeable, which means that it allows certain substances to go through.For substances that are too large, there are vacuoles and transport proteins that assist the large substances.There is also facilitated transport, passive transport, and active transport. Passive transport is the only one where substances can go through the membrane without the cell expending energy.
The passive transport of water through a membrane is?
Osmosis
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)
The movement of substances across the cell membrane that requires the cell to use energy?
It's called active transport. When talking about the cell, it is usually bigger substances that use passages in the cell membrane to access the inner part of the cell, and they need energy to get there. The opposite; passive transport or diffusion, is the movement of dissolved materials through a cell membrane without the use of cellular energy. THis happens with smaller substances.
How do substances get in and out of a cell if they are to big to pass through the cell membrane?
Do you mean how do substances move through a cell membrane if they are too big to transport by passive transport?If so, a cell uses active transport to move large particles in and out of a cell. Active transport includes endocytosis, pinocytosis, and phagocytosis.
Is diffusion an example of active transport or passive transport?
Diffusion is an example of passive transport, like osmosis(the diffusion of water through a membrane).
What is selective transport?
The transport of substances through membrane protein channels
