Question

Vascular tissues of flowering plant develop from

• A. Dermatogen
• B. Periblem
• C. Plerome
• D. Phellogen

Answer 1

The correct option is C Plerome

A. Dermatogen is the primary meristem that forms the outer most layer of a plant or a plant part and forms the epidermis.

B. Periblem is a primary meristem which is located between the plerome and the dermatogen and it forms the cortex.

C. Plerome is the primary meristem that forms the central core of a plant or plant part which gives rise to the stele (includes the vascular tissue, pith and pericycle). The part of plerome from which vascular tissues are formed is called procambium.

D. Phellogen is also known as the cork cambium that forms a layer of cells which produces a secondary protective layer of the stem called the periderm. So, the correct answer is 'Plerome'
