What is Passive Transport?

• Movement of molecules from no concentration to high concentration. Requires no energy

• Movement of molecules from low to high concentration. Requires Energy

• Movement of molecules from high to low concentration. Requires no Energy

• Movement of proteins within the cell.

How long does diffusion last?

• Until the concentration of particles in the system is equal

• Until a region in the system has a smaller concentration of particles than the other

• Until a region in the system has a greater concentration of particles than the other

• Until the particles disappear from the system

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

Tags

NGSS.MS-ESS2-4

During osmosis

• water moves from high to low concentration
• water moves from high to low concentration across a cell membrane

• water moves when energy is used
• proteins are built

Permeable means

• things can pass through
• the concentration levels are different
• it is permanent
• things are stuck
