Question

Secondary growth occurs in ___________.

• A. Riccia
• B. Funaria
• C. Selaginella
• D. None of the above.

Answer 1

The correct option is D None of the above.

When plant growth is observed in roots and stems both, then it is primary growth. In the case of dicot plants, there will be both primary and secondary growth. Therefore these plants exhibit a growth in girth which is known as secondary growth and due to the presence of vascular cambium and cork cambium. Secondary growth generally occurs in most seed plants. Riccia, Funaria, and Selaginella all do not show secondary growth.

So, the correct option is D.
