24. The life function of transport in an organism directly involves those activities used to: • absorb and distribute materials • obtain and break down materials • release energy from food • produce cellular waste products

25. What type of transport does this picture represent? Explain your answer. Active transport Substances are moving from a LOW to HIGH concentration.

26. The diagram above shows the same type of molecule in area A and area B. With the  passage of time, some molecules move from area A to area B. This movement is the result of the process of  __________. passive transport

27. The movement of materials from lower to higher concentration requiring energy is called  (1.) movement (2.) diffusion  (3.) active transport (4.) cell division
