Cell Membrane and Transport

When the concentration of particles inside of a cell is the same as the concentration of particles outside of the cell. 

• active transport

• concentration

• diffusion

• equilibrium

The process where only water is allowed to pass through the cell membrane from a high to low concentration.

• meiosis

• respiration

• diffusion

• osmosis

Large amounts of particles are removed from a cell (pushed out).

• Endocytosis

• Exocytosis

• Permeable

• In high concentration

___________ transport requires energy.

• Passive

• Active

• Osmosis

• Diffusion

transport does not require energy because it moves down a concentration gradient.

• Active

• Passive

A difference in concentration across a given space is:

• Concentration gradient

• Isotonic

• Solutes

• Lipid bilayer

What type of transport is occurring in part A of the diagram?

• Facilitated Diffusion

• Osmosis

• Active Transport

• Diffusion

Molecules naturally move from areas of _______ to ______ concentration.

• lower to higher

• higher to lower

The amount of particles in a given space.

• diffusion

• concentration

• permeable

• active transport
