Biology Bee 8.3 & 8.4

Movement of molecules from an area of higher concentration to an area of lower concentration.

• Active transport

• diffusion

• fusion

• selective permeability

The movement of substances across a cell membrane without the use of energy by the cell

• active transport

• osmosis

• passive transport

• inactive transport

Movement of specific molecules across cell membranes through protein channels from high to low concentration

• active transport

• endocytosis

• exocytosis

• facilitated diffusion

Diffusion of water through a selectively permeable membrane.

• active transport

• osmosis

• endocytosis

• pinocytosis

A solution whose solute concentration is equal to the solute concentration inside a cell(cell size stays the same)

• isotonic

• hypertonic

• hypotonic

• equatonic

A solution in which the concentration of solutes is greater than that of the cell that resides in the solution(cells shrink)

• isotonic

• hypotonic

• hypertonic

• tonic

NGSS.HS-LS1-3

A solution in which the concentration of solutes is less than that of the cell that resides in the solution(cell swells)

• isotonic

• hypotonic

• hypertonic

• endocytonic

The net movement of water out of or into a cell produces a force called

• selection pressure

• osmotic pressure

• blood pressure

• constant pressure

The movement of materials against a concentration difference; requires energy.

• active transport

• passive transport

• facilitated diffusion

• osmosis

Process by which a cell takes material into the cell by infolding of the cell membrane.

• passive transport

• facilitated diffusion

• exocytosis

• endocytosis
