If the CO2 of a respiring plant was removed, then would the plant die because there would be no photosynthesis and no production of starch, or would the plant attempt a recovery and ferment to produce the missing CO2 ?

"During their lifetimes, plants generally give off about half of the carbon dioxide (CO2), that they absorb."... But this topic is about removing all the CO2 including the environment's CO2....(perhaps the chemical sodium hydroxide could be placed in an airtight bag with the plant to absorb the carbon dioxide)…...Would the plant attempt to ferment in the presence of oxygen to try to increase the CO2 in this particular environment?

Quote from: OP
ferment
Plants produce their food by photosynthesis.
Fungi & bacteria don't use photosynthesis, but can break down plant matter in the absence of oxygen by fermentation.
Energy conservation is fundamental to plants and animals, and so cells have various ways of temporarily recovering a small amount of energy, even in the absence of oxygen.

At night plants use something other than photosynthesis.
Whether or not you call it "fermentation" is a better of definition.

Your response above is indicative that energy conservation would enable a second path as depicted in the attachment.
Although the above is for plants, animal cells in this situation should be completely identical. "The Warburg hypothesis sometimes known as the Warburg theory of cancer, postulates that the driver of tumorigenesis is an insufficient cellular respiration caused by insult to mitochondria."
This attachment would support the most recent concept that malignant oxygenated cells have aerobic respiration in parallel with aerobic glycolysis/fermentation, although not in the same proportion.
Thus, "insult to the mitochondria" could have priority over genetics if genetics was not involved with the insult.

Long story short; without CO2, the plant dies.

Yes, but according to Evan_au above, the conservation of energy enters the picture before it dies...…In addition, it dies because of being a plant manufacturing it's own food via photosynthesis....But for an animal cell, the food is provided.... In the case of an animal cell, fermentation (aerobic in this situation) along with aerobic respiration may persist together successfully.
