Secondary growth - vascular cambium
-
The vascular cambium normally gives rise to
Vascular cambium forms secondary xylem and phloem.
During secondary growth, the vascular cambium gives rise to secondary xylem and secondary phloem. Phelloderm is formed by cork cambium.
Secondary growth – cork cambium and periderm
-
Which of the following is made up of dead cells?
Phellem (cork) cells are dead and suberised.
Cork cambium undergoes periclinal division and cuts off thick-walled, suberised, dead cork cells (phellem) towards the outside, and thin-walled living cells, i.e. phelloderm, on the inner side.
Secondary growth – heartwood and sapwood
-
Identify the wrong statement in context of heartwood.
Sapwood, not heartwood, conducts water.
Heartwood is physiologically inactive due to deposition of organic compounds and tylose formation, so it does not conduct water and minerals.
That is every question in Anatomy of Flowering Plants for this filter.
