Question

Quizplus · Accepted Answer

The organelle that stains positive for hydrogen peroxide is most likely a peroxisome. Peroxisomes are known to produce and break down hydrogen peroxide during metabolic processes. This organelle is not likely to be a vacuole, nucleus, glyoxysome or amyloplast as they do not typically have a role in producing or breaking down hydrogen peroxide.
