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.
How do you use passive transport in a sentence?
Passive transport is a process in cells where substances move across the cell membrane without requiring energy input. An example of passive transport is the movement of oxygen and carbon dioxide across the cell membrane through simple diffusion.
What is the name of the process of how things get in and out of the cell?
The process by which substances enter and exit the cell is called cellular transport. It primarily occurs through two main mechanisms: passive transport, which does not require energy, and active transport, which requires energy expenditure by the cell. Examples of passive transport include diffusion and osmosis, while examples of active transport include endocytosis and exocytosis.
Why does active transport allow cells to accumulate substances in high concentrations where as passive means of transport do not?
Active transport uses energy from ATP to carry substances such as glucose to areas where it is required through the use of transport proteins. Whereas, facilitated diffusion is a passive process by which molecules move from an area of high concentration to an area of low concentration and it also depends on kinetic energy. Meaning that the distribution of molecules by facilitated diffusion will be random, whereas, active transport will have control over the direction of the concentration gradient.
What are some non examples of passive transport?
Non-examples of passive transport include active transport mechanisms, where substances move against their concentration gradient using energy (ATP), such as the sodium-potassium pump. Other examples include endocytosis and exocytosis, which involve the engulfing or expelling of materials through vesicle formation, requiring energy. Additionally, filtration, which relies on pressure differences, is not considered passive transport.
What occurs if substances are too large to pass through the cell membrane by active or passive transport?
passive transport
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 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 cell membrane, also known as the plasma membrane, is responsible for regulating the movement of water and substances through processes like active transport and passive transport. It acts as a selectively permeable barrier, allowing certain molecules to pass through while blocking others.
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 are active transport and passive transport different from each other?
Active transport requires energy input to move substances across a membrane against their concentration gradient, while passive transport does not require energy as it moves substances along their concentration gradient. Active transport is selective and requires specific transport proteins, while passive transport occurs through simple diffusion or facilitated diffusion.
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.
What is the name of the process of how things get in and out of the cell?

Examples of passive transport include diffusion and osmosis, while examples of active transport include endocytosis and exocytosis.
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).
Move needed substances or waste materials through the plasma membrane?
transport proteins
