How would a plant respond to an environmental stress such as flooding?

It would use negative feedback to close its stomata and reduce water loss.

It would use positive feedback to increase root growth when more water is available.

It would form air tubes to provide oxygen to the roots through negative feedback.

It would undergo ethanol fermentation to use excess water through positive feedback.

No Problem.

What do you think the answer is?

anonymous · Answer

A . I posted that already the negative feedback seems to be the more plausible choice

anonymous · Answer

Hmm. And what makes it more plausible to you?

anonymous · Answer

To conserve water plants often regulate their guard cells.but when you have flooding you have the destruction of the nutrients in the soil and damage to the gaurd cells which would lead to the influx of water seeping from the plant. So if you use a negative feedback it closes the stomato in order to retain water i think

OK. So what would that make the answer?
