Directions: Complete the paragraph by filling in the blanks.
Gas exchange is one way living cells obtain raw materials and get rid of waste products. Each
stoma on a plant is surrounded by two 11. ____________________ cells that control the size of
the opening. When these cells absorb water, they swell and the stoma opens, letting
12. ____________________ in and 13. ____________________ out. In respiration, organisms
break down food chemically to release 14. ____________________. Respiration that uses oxygen
to break down food chemically is called 15. ____________________. This occurs in the
16. ____________________ in cells. Oxygen is used to break down food to produce
