Is more oxygen consumed and/or more carbon dioxide produced under aerobic respiration in germinating peas and dry peas? If so, why is that?

  1. do you mean in germinating peas OR dry peas?

    dry peas aren't actively growing.  They are dormant.

    "Wet" germinating peas are actively growing.... however they aren't doing photosynthesis.  They are producing a root and a shoot (both are white-- not green-- therefore no chlorophyll,  no chloroplasts -- no photosynthesis--- YET.  They must produce leaves and a green stem for that to happen)

    They are surviving on the endosperm (nutritious starchy stuff from the seed)

    SO.... they are consuming oxygen (cellular respiration) and thus,  producing carbon dioxide as waste.  This is aerobic since it is using oxygen.

    So germinating peas are producing more CO2 and using more O2.

    They are actively metabolizing.  And that is about as simple as it gets without having to get into a bunch of biochemistry.
