The mitochondrion would be affected the most, this scenario is actually called cellular fatige. hope this helps :)
I don’t know this question sorry lil bro :(
Do you want an organ? Large intestine and small intestine seem like they'd be correct.
The original roots of dodder usually die. As a parasitic plant that cannot produce its own chlorophyll, it breaks away from its root system as the roots has no apparent root cap nor apical meristems. Hence the "root" is not performing its very function of water and nutrient uptake. It then produces haustoria, a root-shaped fungi which penetrates host plant which makes the dodder parasitic.
