During secondary growth in the stem:-

1. The amount of secondary xylem produced is more than the secondary phloem as the
cambium is generally more active on the inner side than the outer.

2. the amount of secondary phloem produced is more than the secondary xylem as the cambium is generally more active on the inner side than the outer.

3. the amount of secondary xylem produced is more than the secondary phloem as the cambium is generally more active on the outer side than the inner.

4. the amount of secondary phloem produced is more than the secondary xylem as the cambium is generally more active on the outer side than the inner.
