What is one way osmosis and diffusion are similar?
The similarity is that they both involve the movement of molecules between a membrane. In osmosis, water diffuses through a semi-permeable membrane without energy due to a difference in solute concentration between sides. In active transport, energy is used by the organism to "push" molecules through ports in the membrane, regardless of solute concentration.
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)
How is active transportation different from passive transportation?
The movement of materials across the cell membrane without using cellular energy is called passive transport. The movement of materials against a concentration difference is known as active transport. Active transport requires energy.
How does nutrients cross plasma membrane?
Things like oxygen, CO2 and lipids cross the membrane with simple diffusion. Water can cross the membrane with osmosis when the water moves through a channel protein in the plasma membrane. Glucose, potassium, sodium etc. moves through a carrier protein in the membrane with the process of active movement. In the process of active movement energy is needed and it is given by the glucose or ATP from the cell.
What is net movement of substances across plasma membrane without additional energy?
Diffusion. With the need of energy, it would be called active 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.
Which term refers to the movement of materials through cell membrane without using the cells energy?
active transport

Which activity can occur without use of energy?
Movement of water across the cell membrane
Which activity can occur without the use of energy?
Movement of water across the cell membrane
Assisted transport of a molecule across the cell membrane without an expenditure of energy is known as?
Any movement of molecules into or out of a cell without the expenditure of energy is called diffusion. If the molecule uses special channels to diffuse through the membrane (again, not expending energy), it is called facilitated diffusion.
What is the movement of material through a membrane?
This movement occurs through several mechanisms.
