Given below is a set of six experimental set-ups (A-F), kept in this state for about 24 hours.
In which tube/tubes the limewater will turn milky?

उत्तर
All the five flasks (A-E) containing plant parts will show respiration and thus, the tubes containing limewater will turn milky. The flask F does not contain any plant part. So, there is no respiration and hence, there is no change.
