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 meristem.
Floral meristems are wider than vegetative meristems.
Increase in size of floral meristem is due to larger size of cells as a result of rapid expansion.
Increase in size of floral meristem is due to increased rate of cell division in central cells.
Floral meristems show definite or determinate growth.
Solution
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.
