Question

A flower represents a complex array of functionally specialised structures that differ substantially from vegetative plant body in form and cell types. Select the statement that is not true with regard to floral meristems.

• A. Floral meristems are larger in size than the vegetative meristems
• B. Increase in size of the floral meristem is due to larger size of the cells, which in turn results from rapid cell expansion only
• C. Increase in size of the floral meristem is largely a result of increased rate of cell division in central cells
• D. A floral morphogenesis is controlled by a network of genes in plants

Answer 1

Answer: (B)

During reproductive phase of a shoot apex, the floral meristem broadens, becomes less conical and increases in size. This increase in size is due to an increase in rate of cell division in the central cells. In plants, floral morphogenesis is controlled by a network of genes.
