To pass through the cell membrance, a material must be dissolved in a)carbon dioxide b)water c)salt
a cell's permeability to a substance a)never changes b)can change c) is constant
water, oxygen, and carbon dioxide a)pass freely through a cell membrance b)cannot pass through a cell membrane c)pass slowly through the cell
true or false..
different materials can diffuse into and out of the cell at the same time
diffusion continues until the materials are evenly spread out
molecules continue to move even though diffusion may stop
most large molecules can easily pass throguh the cell by diffusion
carrier molecules help bring molecules into a cell during passive transport
osmosis is a kind of passive transport
when a solution outside the cell becomes salty, the cell loses water by osmosis and shrinks
diffusion is sometimes referred to as passive transport since the cell is not required to use energy
a tea bag works, in part, by osmosis
