  • hold plants securely in soil
  • store surplus food
53
Q

What are the functions of stems?

A
  • support the plant body

be as specific as possible

A

in the grana of the chloroplasts, which are found in the palisade layer

Where does cellular respiration occur?

A

in the cristae of the mitochondria

58
Q

What is the formula for cellular respiration

A

C6H12O6 + O2 —> CO2 + H2O + ENERGY (ATP)

Every time cellular respiration occurs, 38 units of ATP are created.
