Cell Transport & Energy

cell membrane

thin, flexible barrier around a cell; regulates what enters and leaves the cell

3 multiple choice options

Semipermeable

Only certain substances can pass through

3 multiple choice options

diffusion

the process by which molecules move from an area of higher concentration to an area of lower concentration

3 multiple choice options

osmosis

diffusion of water across a selectively permeable membrane

3 multiple choice options

passive transport

Requires NO energy, Movement of molecules from high to low concentration, Moves with the concentration gradient

3 multiple choice options

active transport

Uses energy (ATP); moves material across a cell membrane against a concentration difference

3 multiple choice options

ATP

Energy molecule (adenosine triphosphate) - used for active transport, and any other cell work requiring energy

3 multiple choice options

photosynthesis

Plants use water and carbon dioxide, in the presence of sunlight, to create glucose and oxygen

3 multiple choice options

Photosynthesis equation

6CO2 + 6H2O --> light energy --> C6H12O6 + 6O2

3 multiple choice options
